Freelance Full Stack Developer Jobs in Windsor, CT

Become a part of our caring community

The Lead UI/UX Full Stack Engineer for Platform Quality and Reliability owns the operational health of the NBA platform after it is built. This is a hands-on engineering role first - you are expected to be a significant individual contributor every sprint. You take handoff from the delivery pods and are accountable for ensuring the platform scales, stays up, fails gracefully, and is covered by rigorous testing and observability. You are not building new features - you are making sure what gets built is production-ready and stays that way.

What You'll Own

• Platform reliability - own uptime, performance, and resilience across NBA platform services; identify and resolve bottlenecks, failure points, and scaling constraints before they become incidents
• Hands-on development - actively write and ship production code alongside your team; this is not a supervisory role
• Testing frameworks - build and maintain automated testing infrastructure across unit, integration, and end-to-end layers; establish testing standards and ensure pods are handing off code that meets the bar
• Observability and logging - own the platform's logging, alerting, and monitoring stack; ensure the team has visibility into what the system is doing in production at all times
• Error management - design and enforce error handling patterns across platform services; ensure failures are caught, logged, surfaced, and resolved systematically
• Scalability engineering - evaluate platform components under load and lead efforts to ensure the system scales reliably as member volume and data throughput grow
• Handoff and quality gates - define and enforce the criteria pods must meet before handing off new services or features; own the process that gets code from delivery to production safely
• Contractor management - manage quality and reliability engineers within your pod; set expectations, review work, and hold the team to standards
• Cross-pod coordination - work closely with all delivery pod leads to catch quality and reliability concerns early; be the voice that asks how something breaks before it ships

What You'll Need

• Bachelor's degree in computer science or related field
• 2+ years of project leadership experience
• 5+ years of full stack software engineering experience with at least 1-2 years focused on platform reliability, software quality, or site reliability engineering
• 5+ years of progressive tech experience as a senior developer in large tech projects
• Hands-on experience building and owning testing infrastructure - automated test suites, integration testing, load testing, and end-to-end coverage
• Strong understanding of observability practices: structured logging, distributed tracing, metrics, and alerting
• Experience designing and enforcing error handling and failure management patterns across distributed systems
• Proven ability to lead a small team or pod through delivery and manage contractor resources
• Comfortable reading and working across a polyglot stack - the NBA platform spans Java, Python, Node.js, and TypeScript
• Strong communication skills - you can clearly articulate quality risk to engineering leads and to senior leadership
• Must be passionate about contributing to an organization focused on continuously improving consumer experiences
• Comfort using AI productivity tools (Claude, Copilot, or similar) to accelerate testing, debugging, and analysis

Strong plus

• Resides in Boston, MA
• Master's degree
• Experience with Kubernetes-based platforms and container-level reliability and scaling
• Familiarity with Kafka and event-driven architectures - understanding how failures propagate across async systems
• Background in healthcare, insurance, or other regulated industries where audit trails and compliance are non-negotiable
• Experience with chaos engineering or fault injection testing
• Familiarity with Azure DevOps pipelines and CI/CD quality gates
