Job description

Lead Full Stack Engineer for Platform Quality and Reliability

Location: Boston, MA (Hybrid; occasional on-site time required)

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
• 5+ years of experience designing, developing, and testing of software applications and/or infrastructure
• 4+ years of full stack software engineering experience with at least 1‑2 years focused on platform reliability, software quality, or site reliability engineering
• 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
• Comfort 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

• 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

Work Style

• Remote/work at home nationwide – USA. While this is a remote position, occasional travel to Humana's offices for training or meetings may be required.
• Hybrid – Boston, MA; very minimal travel might be required for training, meetings, and/or conferences

Work Hours

Typical business hours are Monday‑Friday, 8 hours/day, 5 days/week – some flexibility might be possible, depending on business needs.

Pay Range

$128,300 – $176,400 per year
