Member of Technical Staff, AI Research

The role

AI researchers will build agents and training systems that learn to do physics. This involves conducting original research and building training runs, evaluations, and harnesses that ship as working systems.

What you will do

• Do original research on agents and training systems that learn to do physics and publish it.
• Build training runs, evaluations and harnesses that ship as working systems.
• Work in one lane: reinforcement learning and post-training, agents, evaluation and verification, model architectures and training dynamics, or scientific and generative modeling.
• Work with physicists who design verification harnesses and engineers who build training infrastructure.

Required qualifications

• Three or more years of research experience, with recent publications at top venues (NeurIPS, ICML, ICLR, or comparable physics-ML venues).
• Three or more years of hands-on research engineering with the modern ML stack: PyTorch or JAX, training and post-training frameworks, inference engines for rollouts, experiments run on multi-GPU clust
• Depth in at least one of the following: reinforcement learning and post-training, agents, evaluation and verification, model architectures and training methods, or scientific and generative modeling.

Nice to have

• A physics or mathematics background
• Distributed training at cluster scale
• Experience applying agents to simulators, scientific tools, games, or rigorous benchmark suites
• Open-source contributions or research artifacts the community has adopted

Benefits

• Salary
• Benefits
• Meaningful early-stage equity

Before you apply

• Candidates must be authorized to work in the United States.
• PSI is not able to sponsor or take over sponsorship of employment visas for this role, now or in the future.
• PSI may require that the person in this role be a U.S. person (U.S. citizen or national, lawful permanent resident, or individual granted refugee or asylum status) or be eligible to receive required U
