Senior Full-Stack Product Engineer | Node.js, AI-Native (Boosters R&D)

Help Boosters build an early-stage personal digital-security product within Genesis. Own features from idea through release and measurement, develop backend and occasional frontend functionality, shape architecture and AWS infrastructure, and establish reliable agentic engineering workflows. Bring four or more years in backend or backend-focused full-stack engineering and product-company experience. Required skills include Node.js/TypeScript, React or Next.js, PostgreSQL, Redis, REST API design, architecture and system design, AWS, Docker, CI/CD and unit/integration/end-to-end testing. Active use of Cursor, Claude Code, Codex or similar coding agents is expected. Early-stage architecture and engineering-process experience is a strong advantage.
