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.

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:
Solid 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.
