Research Engineer, RL Frontiers for Frontier AI

Etched.ai is building frontier AI systems in San Jose, aimed at advancing RL-centric development for kernel, ASIC, and production pipelines. You will train frontier models to automate complex hardware and software tasks using proprietary simulators and environments.

You will own the post-training stack end to end, build RL environments with hardware engineers, and craft data mixes and benchmarks to push state-of-the-art performance while ensuring ROI.
