Idler builds reinforcement learning environments that teach AI models to code like 0.01% engineers. Our training environments are based on real-world coding scenarios that frontier models will actually encounter. We've closed a multimillion-dollar contract with a leading foundation lab (the largest they've issued to date). Demand is outpacing our capacity to deliver, so we're scaling the team fast.
Job Responsibility:
Build agentic systems that create and QA coding environments at scale
Design and build scaleable systems that generate RL environments
Create automated QA systems to validate environment quality and fairness
Work directly with AI researchers at leading labs to understand what makes training data effective
Support new product lines as we expand beyond coding environments
Requirements:
8+ years of professional software engineering experience
Lead and mentor more junior members of the team
Lead the process of identifying, specifying, and implementing core technology primitives that maximize the leverage of the rest of the team
Understand and own the technology stack end-to-end
US citizen/visa only
What we offer:
