Senior Backend Engineer-Node.js, AI-Native

Roles & Responsibilities What You'll Do Design and build the core Node.js services and REST APIs from scratch, built to scale as we grow. Own system design end to end: service boundaries, data flow, caching, queueing, failure modes, and scale. Ship AI/ML-powered features, including LLM and agentic capabilities. Use LLMs and agentic tooling across the SDLC, from design and code generation to testing and debugging. Model data and optimize SQL/NoSQL queries for performance; integrate with third-party platforms. Debug production issues, own reliability, and set the engineering standards the rest of the team will grow into. Ideal Candidate What You'll Bring Experience: 6+ years building production backend systems in Node.js for B2C products at meaningful scale. System Design: This one matters a lot to us. You can reason clearly about scalability, reliability, and trade-offs under real constraints. Fundamentals: Strong grasp of API design, service-oriented architecture, data structures, algorithms, and clean code. Databases: Depth in SQL and/or NoSQL, data modeling, query optimization, and performance tuning. AI-Native: You already use LLMs and agentic approaches to maximize your own efficiency as an engineer. Mindset: You enjoy the pace and breadth of a small team, and you are happy picking up whatever moves the product forward. Skills: api,rest,system design,sql,ai-native,nosql,node,code,node.js
