Senior Backend Engineer-Node.js, AI-Native

Responsibilities

• 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.
