Lead RL Infra Engineer: Scale Training & Environments

Luma is building unified general intelligence capable of operating in the physical world. We seek an experienced RL at scale engineer to design, build, and scale distributed RL post‑training systems that coordinate trainer, rollout, environment, and reward workloads across thousands of GPUs.

You will own high‑throughput rollout generation, integrate inference engines like vLLM, implement weight synchronization, and support asynchronous/off‑policy schemes while developing agentic environments for
