Senior Flutter Developer builds and maintains cross-platform mobile apps that communicate with hardware peripherals over BLE, working with firmware teams on connected device projects.
If you’re a Senior Flutter Developer who knows what flutter_blue_plus does in production, and you’ve shipped apps that talk to physical devices over BLE, we want to talk. You’d join us on a freelance, time & material basis: you’re paid for the hours you actually work on real client projects. The first three months are about figuring out if we’re a good match. When things work out, and that depends on the work itself, the project pipeline, and business timing, there’s a real path to our core team with a permanent contract and full benefits.
We’ve been designing and co-creating connected devices since 2008. Wearables, smart audio, health-tech hardware for clients like Oura and BOSE, backed by investors like a16z and Founders Fund. We’re 60+ people, fully remote, and AI-native since before LinkedIn influencers discovered the term. Our Flutter work isn’t another generic app: it’s cross-platform code talking to firmware, sensors, and real hardware behavior on both iOS and Android. If your Dart has ever made a physical device do something it couldn’t do before, you already get why we love what we do.
If you like being told exactly what to build every morning, opening Jira, closing Jira, and logging off at 17:01, we’re probably not your people. We look for engineers who ask “why” before “how”, challenge assumptions, and occasionally break things because they were trying something new. We’re AI-native and we expect you to treat AI as a daily multiplier, not a gimmick. What we expect: ownership of what you touch, straight talk when things get complicated, and the kind of curiosity that makes you actually care about the device on the other end of your Bluetooth connection.
Build and maintain Flutter apps that communicate with hardware peripherals over BLE
Make cross-platform code that behaves well on both iOS and Android, not just “compiles on both”
Take part in specifying, planning, and estimating new modules and features
Improve reliability by chasing down the issues QA finds, including the weird ones
Review pull requests and give your teammates feedback that actually helps
Share what you learn: tech talks, internal docs, pair sessions, whatever fits
Work side by side with firmware engineers, designers, QA, and PMs
Use AI tools as part of your daily workflow, not as a party trick
Fully remote. We have a pet-friendly office in Warsaw and a coworking space in Gdansk if walls and coffee machines motivate you, but nobody will ask why you’re not there. Working hours are flexible: most of the team operates between 10:00 and 18:00 CET, and that’s when most meetings happen. Evening calls with US-based clients (up to ~20:00) are part of the rhythm, sometimes a couple of times a week, always planned ahead. You’ll be part of the Mobile chapter for knowledge-sharing, and at the same time on a project squad led by a PM for day-to-day delivery.

Truly flexible hours: you organize your day
Fully remote, with pet-friendly Warsaw office + Gdansk cowork if you want them
Access to our internal knowledge-sharing: tech talks, experiments, side projects
When the first 3 months work out, and that depends on the work, the project pipeline, and business timing, there’s a real path to a permanent contract with a fixed monthly salary, 26 days paid leave, 10 sick days, Saltus medical care, and a training budget
No sugarcoating: during the freelance period there’s no paid leave or medical benefits. Those come with the permanent contract, and we’re transparent about that upfront.
We aim to give you space to ramp up before jumping into live project work, but this is a real company with real deadlines: if the project needs you sooner, we’ll make sure you have the support to hit the ground running. You’ll get paired with a technical buddy and tackle progressively bigger tasks, so both sides can see how the collaboration feels. Feedback comes early and often, no one waits three months to tell you something isn’t working. If it’s great, you’ll know. If something needs adjusting, you’ll hear about it while there’s still time to adjust.
The entire process is in English. All interviews are recorded for internal evaluation purposes.
Application with a few screening questions
HR call, ~45 min, casual
Technical meeting, ~90 min, with the technical team (may include live coding)
Final feedback within a few days
Once we’re in touch, you’ll hear from us fast. We don’t ghost and we don’t drag.
intent is an equal opportunity employer. We care about what you can do, not where you come from. Send us your CV and a few words about why this caught your eye. Bonus points if you share something you’ve built that made you proud.

Senior firmware engineer designs and ships embedded software for connected devices (wearables, audio, health-tech), working with hardware teams and clients to deliver production-quality firmware on microcontrollers like ESP32/STM32.
If you’re a firmware engineer who’s just as comfortable reading a schematic as writing C, and you’ve spent serious time inside ESP32 or STM32 projects, we want to talk. You’d join us on a freelance, time & material basis: you’re paid for the hours you actually work on real client projects. The first three months are about figuring out if we’re a good match. When things work out, and that depends on the work itself, the project pipeline, and business timing, there’s a real path to our core team with a permanent contract and full benefits.
We’ve been designing and co-creating connected devices since 2008. Wearables, smart audio, health-tech hardware for clients like Oura and BOSE, backed by investors like a16z and Founders Fund. We’re 60+ people, fully remote, and AI-native since before LinkedIn influencers discovered the term. Firmware is where most of our products actually live or die: BLE stacks, power budgets, sensor pipelines, OTA. If you like the kind of bug that only shows up at -10°C with a flat battery, you’ll feel at home.
If you like being told exactly what to flash every morning and logging off the second the linker finishes, we’re probably not your people. We look for engineers who ask “why” before “how”, challenge assumptions, and dig into the hardware when the symptoms don’t add up.

What we expect: ownership of what you touch, straight talk when something on the board doesn’t behave, and the kind of curiosity that makes you actually care about the device, not just the code that ships to it.
Plan, develop, and ship firmware for connected devices: wearables, audio, health-tech hardware
Gather and analyze requirements from clients, then turn them into something that actually works on real silicon
Consult clients and internal teams on stacks, tools, and trade-offs

Genuine curiosity about the devices you build, not just the bits flying around them
Senior backend engineer owns technical architecture and infrastructure decisions for IoT/connected device projects, designing data pipelines and cloud systems while mentoring team members.
If you’re a backend engineer who doesn’t just build what’s asked, but shapes how it’s built, we want to talk. We’re looking for someone who can own the technical direction of a project end to end: architecture, infrastructure, trade-offs, and the conversations that come with them. You’d join us on a freelance, time & material basis: you’re paid for the hours you actually work on real client projects. Full capacity from the start. The first three months are about figuring out if we’re a good match. When things work out, and that depends on the work itself, the project pipeline, and business timing, there’s a real path to our core team with a permanent contract and full benefits.
We’ve been designing and co-creating connected devices since 2008. Wearables, smart audio, health-tech hardware for clients like Oura and BOSE, backed by investors like a16z and Founders Fund. We’re 60+ people, fully remote, and AI-native since before LinkedIn influencers discovered the term. We use AI every day, in actual work, not just in company decks. Our backend isn’t generic CRUD: it’s the cloud spine of physical devices, the layer where firmware meets data pipelines, and where one bad architectural call shows up in a sensor reading six months later.
If your comfort zone is a well-defined Jira board, clear specs, and someone else making the architectural calls, this isn’t going to work. We’re not hiring a senior developer who executes well. We’re hiring someone who decides what gets built, how it gets built, and why. Someone who walks into a room full of ambiguity and starts creating structure, not waiting for it. If you need a ticket to start moving, if “that’s not in the requirements” is a sentence you use often, or if you’d rather not be the one explaining a technical trade-off to a client, we’re probably not your people. We’re AI-native and we expect you to treat AI tools as a daily multiplier, not a gimmick.
Own and evolve the backend architecture for IoT projects: data ingestion pipelines, API design, infrastructure decisions
Make technical trade-off calls and defend them clearly to the team and to clients
Design and maintain cloud infrastructure on AWS (EKS, Aurora, DynamoDB, Timestream, S3) with production-grade reliability
Lead technical discussions: RFCs, architecture reviews, post-mortems, because you see the need, not because someone asked
Mentor other backend engineers, raise the bar on code quality, and set patterns others can follow
Work side by side with firmware engineers, mobile developers, QA, PMs, and clients
Use AI tools as part of your daily workflow, not as a party trick
Challenge product and technical assumptions when something doesn’t add up, even when it means a harder conversation

Graduate software engineer contributes to open source projects across Linux, cloud infrastructure, containers, and security in various programming languages.
Canonical is a leading provider of open source software and operating systems to the global enterprise and technology markets. Our platform, Ubuntu, is very widely used in breakthrough enterprise initiatives such as public cloud, data science, AI, engineering innovation, and IoT. Our customers include the world’s leading public cloud and silicon providers, and industry leaders in many sectors. The company is a pioneer of global distributed collaboration, with 1200+ colleagues in 75+ countries and very few office-based roles. Teams meet two to four times yearly in person, in interesting locations around the world, to align on strategy and execution.
The company is founder led, profitable and growing.
We are hiring 2025 and 2026 Graduate Software Engineers into engineering teams around the world. As a global platform company we offer a wide range of software engineering challenges, in both open source products and commercial business systems. We have teams that work in a variety of languages, typically Python, Golang, Rust, C/C++, JavaScript and of course… Bash. We work from the very lowest levels of the Linux system - BIOS and boot loaders, firmware, kernel and drivers, all the way up to desktop applications and containers. We work on tiny devices like the Raspberry Pi and new RISC-V boards, all the way up to supercomputers, clouds and Kubernetes clusters. We work on compilers and toolchains, and we work on security, cryptography, performance and documentation. Some of our teams focus on packaging thousands of pieces of software, others focus on deep contributions to a single body of code.
If you are excited about the potential that open source has for humanity and the enterprise, you have outstanding results in your academic career, and you are excited to contribute to the open source stack, this is the best way to apply to Canonical. We will work with you to identify teams and projects that would be interesting and a good fit for your skills and motivations. The process is highly competitive, it will require effort and excellence to succeed if you apply here.
Most of our engineering teams work from home. We try to align a single team in a single time zone - EMEA (Europe, Middle East and Africa), APAC (Asia Pacific and Indian Ocean), and AMER (North, South and Central Americas). Even though you work from home, we try to ensure you always have colleagues alongside to coach and mentor you, and for the companionship of shared problem solving and pair programming. Larger projects have multiple teams and might span the globe. We work with the open source community and specialize in building teams that work well in the ‘fishbowl’ of open source engineering. This is full time work, five days a week, often solving hard problems with significant responsibility. We don’t generally work weekends and nights and we do enjoy good holidays but we also expect productive and intense engagement Monday to Friday.
We bring all our engineering teams together in person twice a year for a deep ‘sprint’ with other teams to stimulate discussion and enable a wide range of career development paths. This is a fantastic way to demonstrate and develop your skill in software, learn about a wide range of technologies, make a meaningful impact to open source, and see some very interesting new cities that you might never otherwise get to visit.
If you find the open source stack amazing, and you have been a consistent high-performing student in your school and university, then this will be a challenging and exciting start to your career.
Location: This is a Globally remote role.
We consider geographical location, experience, and performance in shaping compensation worldwide. We revisit compensation annually (and more often for graduates and associates) to ensure we recognize outstanding performance. In addition to base pay, we offer a performance-driven annual bonus or commission. We provide all team members with additional benefits which reflect our values and ideals. We balance our programs to meet local needs and ensure fairness globally.
Canonical is a pioneering tech firm at the forefront of the global move to open source. As the company that publishes Ubuntu, one of the most important open source projects and the platform for AI, IoT and the cloud, we are changing the world of software. We recruit on a global basis and set a very high standard for people joining the company. We expect excellence - in order to succeed, we need to be the best at what we do. Most colleagues at Canonical have worked from home since its inception in 2004. Working here is a step into the future, and will challenge you to think differently, work smarter, learn new skills, and raise your game.
We are proud to foster a workplace free from discrimination. Diversity of experience, perspectives, and background create a better work environment and better products. Whatever your identity, we will give your application fair consideration.

Senior firmware engineer designs and develops embedded software for connected devices like wearables and health-tech hardware, working with ESP32/STM32 platforms and managing full lifecycle from requirements to testing.
If you’re a firmware engineer who’s just as comfortable reading a schematic as writing C, and you’ve spent serious time inside ESP32 or STM32 projects, we want to talk. You’d join us on a freelance, time & material basis: you’re paid for the hours you actually work on real client projects. The first three months are about figuring out if we’re a good match. When things work out, and that depends on the work itself, the project pipeline, and business timing, there’s a real path to our core team with a permanent contract and full benefits.
We’ve been designing and co-creating connected devices since 2008. Wearables, smart audio, health-tech hardware for clients like Oura and BOSE, backed by investors like a16z and Founders Fund. We’re 60+ people, fully remote, and AI-native since before LinkedIn influencers discovered the term. Firmware is where most of our products actually live or die: BLE stacks, power budgets, sensor pipelines, OTA. If you like the kind of bug that only shows up at -10°C with a flat battery, you’ll feel at home.
If you like being told exactly what to flash every morning and logging off the second the linker finishes, we’re probably not your people. We look for engineers who ask “why” before “how”, challenge assumptions, and dig into the hardware when the symptoms don’t add up. We’re AI-native and we expect you to treat AI as a daily multiplier, not a gimmick. What we expect: ownership of what you touch, straight talk when something on the board doesn’t behave, and the kind of curiosity that makes you actually care about the device, not just the code that ships to it.
Plan, develop, and ship firmware for connected devices: wearables, audio, health-tech hardware
Gather and analyze requirements from clients, then turn them into something that actually works on real silicon
Consult clients and internal teams on stacks, tools, and trade-offs
Work side by side with mobile, backend, and QA to make sure the device and its companion app actually understand each other over BLE
Test firmware releases and write the documentation that future-you will thank present-you for
Estimate your own work and flag risks before they become blockers
Push for better practices: code reviews, patterns, knowledge-sharing inside and outside the chapter
Use AI tools as part of your daily workflow, not as a party trick
Fully remote. We have a pet-friendly office in Warsaw and a coworking space in Gdansk if walls and coffee machines motivate you, but nobody will ask why you’re not there. Working hours are flexible: most of the team operates between 10:00 and 18:00 CET, and that’s when most meetings happen. Evening calls with US-based clients (up to ~20:00) are part of the rhythm, sometimes a couple of times a week, always planned ahead. You’ll be part of the Firmware & Hardware chapter for knowledge-sharing, and at the same time on a project squad led by a PM for day-to-day delivery.

Hands-on ESP32 experience, including ESP-IDF and ESP-ADF
STM32 experience in production projects

Toolchain fluency: CMake, GCC, Python-based tooling
Familiarity with IoT protocols like MQTT and WebSockets
A feel for the connected device landscape: IoT, home automation, wearables, automotive
English at B2+, written and spoken, because our clients are mostly US-based
Self-reliance, ownership, and the kind of communication where people don’t have to guess what you meant
Rapid hardware prototyping on Arduino, Raspberry Pi, BeagleBone, Nucleo

Fleet deployment and management with AWS IoT Core, GCP Cloud IoT, Azure IoT, or similar
Cryptography in embedded contexts
Audio paths: encoding, decoding, mixers
Machine learning on embedded targets
Rust in firmware
FreeRTOS, Zephyr, or other embedded operating systems
Genuine curiosity about the devices you build, not just the bits flying around them
Senior backend engineer owns IoT cloud architecture, infrastructure decisions, and technical strategy across data pipelines and AWS infrastructure.
If you’re a backend engineer who doesn’t just build what’s asked, but shapes how it’s built, we want to talk. We’re looking for someone who can own the technical direction of a project end to end: architecture, infrastructure, trade-offs, and the conversations that come with them. You’d join us on a freelance, time & material basis: you’re paid for the hours you actually work on real client projects. Full capacity from the start. The first three months are about figuring out if we’re a good match. When things work out, and that depends on the work itself, the project pipeline, and business timing, there’s a real path to our core team with a permanent contract and full benefits.
We’ve been designing and co-creating connected devices since 2008. Wearables, smart audio, health-tech hardware for clients like Oura and BOSE, backed by investors like a16z and Founders Fund. We’re 60+ people, fully remote, and AI-native since before LinkedIn influencers discovered the term. We use AI every day, in actual work, not just in company decks. Our backend isn’t generic CRUD: it’s the cloud spine of physical devices, the layer where firmware meets data pipelines, and where one bad architectural call shows up in a sensor reading six months later.
If your comfort zone is a well-defined Jira board, clear specs, and someone else making the architectural calls, this isn’t going to work. We’re not hiring a senior developer who executes well. We’re hiring someone who decides what gets built, how it gets built, and why. Someone who walks into a room full of ambiguity and starts creating structure, not waiting for it. If you need a ticket to start moving, if “that’s not in the requirements” is a sentence you use often, or if you’d rather not be the one explaining a technical trade-off to a client, we’re probably not your people. We’re AI-native and we expect you to treat AI tools as a daily multiplier, not a gimmick.
Own and evolve the backend architecture for IoT projects: data ingestion pipelines, API design, infrastructure decisions
Make technical trade-off calls and defend them clearly to the team and to clients
Design and maintain cloud infrastructure on AWS (EKS, Aurora, DynamoDB, Timestream, S3) with production-grade reliability
Lead technical discussions: RFCs, architecture reviews, post-mortems, because you see the need, not because someone asked
Mentor other backend engineers, raise the bar on code quality, and set patterns others can follow
Work side by side with firmware engineers, mobile developers, QA, PMs, and clients
Use AI tools as part of your daily workflow, not as a party trick
Challenge product and technical assumptions when something doesn’t add up, even when it means a harder conversation

When things work out, and that depends on the work itself, the project pipeline, and business timing, there’s a real path to our core team with a permanent contract and full benefits.
We’ve been designing and co-creating connected devices since 2008. Wearables, smart audio, health-tech hardware for clients like Oura and BOSE, backed by investors like a16z and Founders Fund. We’re 60+ people, fully remote, and AI-native since before LinkedIn influencers discovered the term. We use AI every day, in actual work, not just in company decks. If your Swift has ever made a physical device do something it couldn’t do before, you already get why we love what we do.
If you like being told exactly what to build every morning, opening Jira, closing Jira, and logging off at 17:01, we’re probably not your people. We look for engineers who ask “why” before “how”, challenge assumptions, and occasionally break things because they were trying something new. We’re AI-native and we expect you to treat AI as a daily multiplier, not a gimmick. What we expect: ownership of what you touch, straight talk when things get complicated, and the kind of curiosity that makes you actually care about the device on the other end of your Bluetooth connection.
Build and maintain iOS apps that communicate with hardware peripherals over BLE
Take part in specifying, planning, and estimating new modules and features
Write and maintain unit tests (XCTest, Quick/Nimble) with a TDD mindset
Keep CI/CD pipelines in shape (GitHub Actions, Bitrise, Travis)
Review pull requests and give your teammates feedback that actually helps
Share what you learn: tech talks, internal docs, pair sessions, whatever fits
Work side by side with firmware engineers, designers, QA, and PMs
Use AI tools as part of your daily workflow, not as a party trick
Fully remote. We have a pet-friendly office in Warsaw and a coworking space in Gdansk if walls and coffee machines motivate you, but nobody will ask why you’re not there. Working hours are flexible: most of the team operates between 10:00 and 18:00 CET, and that’s when most meetings happen. Evening calls with US-based clients (up to ~20:00) are part of the rhythm, sometimes a couple of times a week, always planned ahead. You’ll be part of the Mobile chapter for knowledge-sharing, and at the same time on a project squad led by a PM for day-to-day delivery.
90-180 PLN/h net B2B, depending on your experience
Truly flexible hours: you organize your day
Fully remote, with pet-friendly Warsaw office + Gdansk cowork if you want them
Access to our internal knowledge-sharing: tech talks, experiments, side projects
When the first 3 months work out, and that depends on the work, the project pipeline, and business timing, there’s a real path to a permanent contract with a fixed monthly salary, 26 days paid leave, 10 sick days, Saltus medical care, and a training budget
No sugarcoating: during the freelance period there’s no paid leave or medical benefits. Those come with the permanent contract, and we’re transparent about that upfront.
We aim to give you space to ramp up before jumping into live project work, but this is a real company with real deadlines: if the project needs you sooner, we’ll make sure you have the support to hit the ground running. You’ll get paired with a technical buddy and tackle progressively bigger tasks, so both sides can see how the collaboration feels. Feedback comes early and often, no one waits three months to tell you something isn’t working. If it’s great, you’ll know. If something needs adjusting, you’ll hear about it while there’s still time to adjust.
The entire process is in English. All interviews are recorded for internal evaluation purposes.
Application with a few screening questions
HR call, ~45 min, casual
Technical meeting, ~90 min, with the technical team (may include live coding)
Final feedback within a few days
Once we’re in touch, you’ll hear from us fast. We don’t ghost and we don’t drag.
intent is an equal opportunity employer. We care about what you can do, not where you come from. Send us your CV and a few words about why this caught your eye. Bonus points if you share something you’ve built that made you proud.
3+ years writing production Swift
Strong, hands-on BLE integration experience (not “I read about it once”)
Structured concurrency in Swift: you know it, you use it
CI/CD experience: GitHub Actions, Bitrise, or Travis
Unit testing discipline: XCTest, Quick/Nimble, or similar, with a TDD mindset
English at B2+, written and spoken, because our clients are mostly US-based
Problem-solving over line-counting: we’ll take a creative thinker over a fast typist any day
High coding standards and an eye on what’s new in the iOS world
Initiative, ownership, and the kind of communication where people don’t have to guess what you meant
Experience with other mobile platforms (Android, Flutter, KMM)
Previous IoT or connected device projects
Functional reactive programming (Combine, RxSwift)
Agile/Scrum experience
Genuine curiosity about the things you build, not just the code behind them
