Job summary

Prime Intellect, Inc. is building the open frontier AI stack and seeking researchers to create post-training and agent systems for regulated environments. You will work across data, privacy, and infrastructure constraints while collaborating with customers and researchers.

Qualifications

• Relevant experience: RL/post-training, private ML systems, high-assurance evaluation, agent safety, regulated-domain ML, or deployment under strict data and infrastructure constraints.
• Hands-on experience building and debugging model-training, post-training, agent, evaluation, or closely adjacent experimental loops.
• Strong experimental judgment: meaningful baselines, careful trace inspection, clear failure attribution, and a willingness to change direction when the evidence changes.
• Evidence of exceptional work: publications, open-source systems, benchmarks, and shipped products as evidence of exceptional work.
• Comfort owning ambiguous problems and keeping partners and teammates current as you resolve them.

Responsibilities

• Improvement loops that run end to end inside the operator's boundary, from trace selection to deployed update.
• Agents with explicit permissions, evidence trails, bounded tools, and human checkpoints.
• Evaluations that test reliability, calibration, recovery, and compliance with real procedures.
• Experiments on how privacy, access, and infrastructure constraints change learning, with methods that transfer across high-assurance settings.
