Senior Full Stack Engineer - NBA

About this role

Become a part of our caring community   The Senior Full Stack Engineer builds and evolves the NBA platform's Action Library and Command Center experience, the operational system used by business and program teams to create, configure, govern, and publish member actions across the enterprise. Built on React, Node.js, PostgreSQL, and Kafka-based integration patterns, the platform serves as the primary control plane for authoring and managing actions throughout the member journey. This is a hands-on engineering role with a strong front-end focus: you design and build modern user experiences, develop the APIs and services that support them, and partner closely with product, design, and platform teams to deliver scalable, production-ready solutions.

Key Responsibilities • Front-end engineering — Design and build responsive, accessible, and performant user interfaces using React and TypeScript. • Full stack development — Deliver features across the stack, including React applications, Node.js/Fastify services, PostgreSQL data models, and platform integrations. • Action Library development — Build capabilities that allow business users to create, configure, version, preview, govern, and publish member actions. • API engineering — Develop and maintain REST APIs using contract-first principles, shared TypeScript models, and schema validation patterns. • Data modeling — Design and implement PostgreSQL schemas, queries, and data access patterns that support reliable and performant user experiences. • Workflow integration — Develop integrations with orchestration, decisioning, and Kafka-based publishing services to ensure actions flow reliably through the NBA ecosystem. • User experience design — Translate complex business workflows into intuitive experiences that improve efficiency, usability, and adoption. • Quality engineering — Build automated tests, participate in code reviews, and deliver secure, maintainable, production-quality software. • Cross-team collaboration — Work closely with engineering, product, and platform teams to align requirements, integrations, and technical solutions.

Use your skills to make an impact   Required Qualifications • 5+ years of full stack software engineering experience with strong React and TypeScript expertise. • Experience building production-grade web applications using modern React architecture and component-based design patterns. • Strong Node.js/TypeScript backend development experience building REST APIs and service-oriented applications. • Experience working with PostgreSQL or other relational databases, including schema design, query optimization, and data modeling. • Understanding of modern front-end architecture including state management, routing, accessibility, performance optimization, and responsive design. • Experience with API contracts, schema validation, and strongly typed development practices. • Familiarity with containerized application deployment, CI/CD pipelines, and cloud-native application development. • Strong testing discipline, including unit, integration, and end-to-end testing approaches. • Strong communication skills and the ability to collaborate effectively across engineering and product teams.

Preferred Qualifications • Experience with React 19, TanStack Router, Query, Form, and Table. • Experience with Fastify, Prisma, Drizzle ORM, Redis, and PostgreSQL performance tuning. • Familiarity with OpenAPI specifications, code generation, and contract-first API development. • Experience with Kafka and event-driven architectures. • Experience building workflow-driven applications, operational consoles, or enterprise business tooling. • Familiarity with Kubernetes, Azure DevOps, ArgoCD, and modern deployment pipelines. • Experience with OpenTelemetry, distributed tracing, and observability platforms. • Experience implementing OAuth 2.0, Azure AD, SSO, RBAC, or enterprise identity solutions. • Background in healthcare, insurance, or another regulated industry with compliance and PHI handling requirements.

Success Indicators • State transitions are precise, deterministic, and resilient to retries

• Side effects reliably occur exactly once, even during failures or replays

• Systems recover gracefully from crashes and redeployments

• AI-driven tooling decreases defect rates and expedites debugging

• The state layer is trusted as the definitive source of truth across engineering teams

Why This Role is Critical In contemporary automated platforms, correctness and reliability hinge on the integrity of state, not just requests. This role ensures that every state transition and side effect is executed once—and only once—providing a solid foundation for trust, reliability, compliance, and scalability throughout the system.
