RL Research Engineer — Own GPU Cluster & Unlimited Compute

Frontier Arc in San Francisco seeks a Research Engineer to push the core RL research agenda. You’ll own the end-to-end loop—from designing policies to training, evaluation, and interpretation—working on a proprietary simulator that aims to replace costly real-world data collection.

You’ll join a small, technically serious team with high agency, building models that transfer from sim to real hardware. Expect on-site work, a fast-paced lab environment, and the opportunity to tackle difficult
