About the Opportunity

We're partnering with a stealth AI company building infrastructure that powers reinforcement learning (RL) environments for some of the world's leading AI labs. Their systems operate directly within the AI training loop, helping evaluate, improve, and deploy next‑generation AI models. This is highly applied, production‑focused engineering work with real‑world impact.

What You'll Do

• Build full‑stack applications end‑to‑end (frontend, backend, and infrastructure)
• Transform loosely defined concepts into production‑ready products
• Design and implement systems supporting AI agents and RL workflows
• Deliver high‑quality software rapidly without sacrificing maintainability
• Collaborate directly with founders, researchers, and engineering leadership
• Own projects from specification to deployment with minimal oversight

How You'll Work

• Operate with a high degree of auton...
