Job Level
About the role
- You'll own features end-to-end: from database schemas to React components to the AI agents that make our platform intelligent.
- Some weeks you're building robust backend systems.
- Other weeks you're experimenting with the latest models to create features that feel like magic.
- Most weeks, it's both.
Requirements
- TypeScript across the stack: Strong proficiency in TypeScript, Node.js, React, and Next.js—you'll move fluidly between backend and frontend
- Production AI experience: You've shipped LLM-powered features to real users—whether that's agentic systems, conversational AI, intelligent automation, or integrating models into applications. We care that you've done it, not how deep you went.
- Product engineering mindset: You care about user experience, not just technical implementation. You'll help define the "what" not just build the "how."
- Database fluency: PostgreSQL experience—efficient queries, sensible schemas, understanding of how data flows through a system
- Startup velocity: 5+ years of experience with meaningful time in fast-paced environments where you owned problems end-to-end
- Ship-first mentality: You default to shipping and iterating. You're deliberate about trade-offs but allergic to over-engineering.
- AI coding tool mastery: You're fluent with tools like Claude Code, Cursor, Copilot, or similar. You don't just use them—you've developed workflows that make you dramatically faster. You understand when to lean on AI assistance and when to think for yourself.
Benefits
- AI playground: We're testing every model available. Constant experimentation. Freedom to build and break things.
- Real users, real feedback: Thousands of engineers on the platform. Your code ships and you see impact immediately.
- Ground floor timing: Early enough to shape architecture and culture. Established enough to have traction and resources.
- No red tape: Flat structure, minimal documentation overhead, streamlined decisions. We optimize for speed.
- Repeat founders: Leadership that's done this before. Sustainable pace. No theater.
