San Jose, California · Full-time · Posted Oct 28, 2026
- Education
- Completing or recently completed a BS degree in a specified or related discipline; an MS is preferred.
About the job
Conduct research and build training, evaluation, and oversight methods to make frontier models and agents safer, especially in tool use, code execution, and long-horizon tasks.
What you'll do
- Train agents for safe and controllable behavior using RL, SFT, and preference optimization; design environments, rewards, and data to reduce unsafe actions.
- Assess frontier risks and build safeguards, automated red teaming, monitoring, and oversight methods.
- Analyze failures, run controlled experiments, and collaborate with research, engineering, infrastructure, and product teams to deploy effective methods.
What they ask for
- Completing or recently completed a BS in Computer Science, Electrical Engineering, Electrical and Computer Engineering, Physics, Mathematics, or a related discipline.
- Strong foundations in ML, deep learning, and statistics, plus research or engineering experience in LLMs, RL, or related fields.
- Proficiency in Python and PyTorch (or similar), including implementing algorithms, building experiment pipelines, and debugging.
- Deep hands-on experience in at least one of agent RL, model training, dataset development, agent systems, evaluation, or ML infrastructure.
Nice to have
- Completing or recently completed an MS in a listed or related discipline.
- Experience with SFT, RLHF/RLAIF/RLVR, distributed training, automated red teaming, or related safety research and risk evaluation.
