SEKAI revolutionize how digital twins are being built, used and scaled! Backed by a16z speedrun.
About the role
We're doubling down on creation quality and reliability. This is a key role with real ownership: you'll run the lane end-to-end and set the technical bar for agent-driven app generation. We want people who think in systems, not solutions. How do we generate fully autonomous software for recreational use? How do we generate it fast? And how do we do it tastefully? This role lives at the bleeding edge of what current AI can do — if those questions excite you, it's for you.
What they're looking for
- You've built agentic systems — tool use, orchestration, retry/repair loops, context management — whether on raw provider APIs or frameworks like LangGraph, PydanticAI, Google ADK, Pi-mono, or Vercel AI SDK
- You understand the tradeoffs well enough to know when the framework gets in your way. Experience with distributed / real-time systems
- A research-and-ship mindset: you treat open-ended problems as experiments, and you care as much about getting the result into production as discovering it Strong software engineering fundamentals, with depth in Python and/or TypeScript
- A track record of shipping and operating production systems A history of owning hard problems end to end — you can point to systems you built and the outcomes they drove, not just the tech you touched
- Strong product instincts: you can translate user-experience goals into system-design decisions
