Backend Developer

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.
