• Maintain high automated test coverage and engineering quality standards

• Conduct peer code reviews and enforce clean coding practices

• Troubleshoot production issues and performance bottlenecks efficiently

Monitoring, Reliability & Security

• Monitor systems using Datadog, New Relic, Grafana, Prometheus, or similar tools

• Implement logging, alerting, and observability best practices

• Apply secure coding principles aligned with OWASP Top 10 standards

• Ensure systems comply with GDPR, SOC 2, HIPAA, or other relevant compliance requirements

• Support uptime, resiliency, and disaster recovery initiatives

Collaboration & Technical Leadership

• Collaborate with product managers and designers to turn requirements into scalable technical solutions

• Lead technical discussions and contribute to architecture planning

• Mentor junior and mid-level engineers through reviews, guidance, and pairing

• Contribute to long-term technical roadmaps and engineering standards

• Participate actively in sprint ceremonies, planning, and technical estimation

What Makes You a Perfect Fit

• Strong full-stack engineer capable of owning features end-to-end

• Experienced in scaling systems and improving infrastructure reliability

• Hands-on problem solver who thrives in technical environments

• Strong communicator who collaborates effectively across teams

• Balances rapid execution with maintainable architecture and code quality

• Passionate about mentoring and improving engineering culture

Required Experience & Skills

• 5+ years of professional full stack software engineering experience

• Strong proficiency in JavaScript/TypeScript with React and Node.js

• Experience with relational and NoSQL databases (Postgres, MySQL, MongoDB)

• Hands-on cloud deployment experience using AWS, GCP, or Azure

• Strong understanding of Git workflows and CI/CD pipelines

• Experience building APIs, scalable applications, and production systems

• Strong debugging, optimization, and troubleshooting skills

Ideal Experience & Skills

• Experience leading architecture reviews and technical design sessions

• Familiarity with Infrastructure-as-Code tools (Terraform, Pulumi, CloudFormation)

• Background building SaaS or high-traffic applications

• Experience with microservices, event-driven systems, or serverless architectures

• Familiarity with Kubernetes orchestration and distributed systems

• Exposure to observability, performance engineering, and cloud cost optimization

What Does a Typical Day Look Like?

A Senior Full Stack Software Engineer’s day revolves around building features, improving infrastructure, and ensuring system reliability. You will:

• Join standups and align with engineering and product teams on sprint priorities

• Build full-stack features across APIs, databases, and front-end interfaces

• Review pull requests and mentor engineers through technical feedback

• Investigate and resolve bugs, outages, and performance bottlenecks

• Collaborate with product managers and designers on implementation strategies and UX flows

• Deploy updates through CI/CD pipelines and monitor infrastructure health

• Contribute to technical planning, architecture decisions, and platform improvements

In essence: you are both a hands-on builder and technical leader, ensuring systems remain scalable, reliable, secure, and continuously improving.
