Post-Training ML Research Engineer RL & Production
WARP CORP
Warp in California’s South San Francisco area is seeking a post-training research engineer/scientist to turn advanced models into practical production capabilities. You will own the post-training loop, from identifying capability gaps through evaluation, data development, training, deployment, and feedback, with a focus on fast, reproducible experimentation.
You will develop RL training methods, design reward signals, curate training data from model failures and product feedback, and collaborate
