About the role
Key Skills: Node.js, LLM, SQL
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.
