FullStack Software Engineer
We are looking for a Generalist Software Engineer with experience to join our lean, highly technical team at the frontier of AI. We need a smart, capable engineer with strong first-principles thinking to help us solve novel problems that break traditional engineering best practices. You will be instrumental in building our 'world engine,' a complex, interconnected environment that enables AI models to learn and interact with a simulated digital world, directly impacting the next generation of agentic AI.
What will you be doing?
- Own and build software 'replicas' from the ground up, integrating them into our core 'world engine' to create a vast, interactive environment for AI agents.
- Develop services that ensure data coherence across the simulated digital world, tackling unique challenges like making a virtual baseball game get canceled during a simulated hurricane.
- Solve novel, first-principles engineering problems that don't have existing patterns or solutions, breaking conventional best practices to build for the future of AI.
- Go beyond typical full-stack tasks to reason about and build the fundamental infrastructure needed for our complex simulation environment.
- Collaborate directly with researchers at leading Frontier AI labs, translating their needs into new capabilities and preempting future research directions.
Seniority
2+ years of experience as a software engineer.
Work experience
Has shipped user-facing features end-to-end (bonus for AI-LLM-powered features).
Experience at an AI-forward VC-backed startup or top tech company (e.g., FAANG).
