About the role
- Our mission is to discover and commercialize transformative physics breakthroughs at scale with artificial superintelligence, safely, verifiably, and for broad public benefit.
- The last century's golden age of physics gave us transistors, lasers, and nuclear energy.
- We believe artificial superintelligence will unlock the next one.
Responsibilities
- Core AI is the organization responsible for the models, agents, and training systems that do physics: the AI research and infrastructure that Applied AI and Physics build on.
- Partner with Applied AI, which turns Core AI's work into products and customer engagements, and with Engineering, which owns the platform infrastructure your systems train, evaluate, and run on.
- Core AI is only as valuable as what these teams can build on top of it.
- Hire and develop world-class talent, keeping the bar high while Core AI grows.
- Set the Core AI roadmap and own the resulting AI research portfolio in service of one goal: making PSI's AI systems better at doing real physics.
- Own the people and the delivery, set direction, kill weak lines of work, and double down on what works.
Requirements
- You have personally built and trained systems that beat non-trivial baselines, and you can still do so.
- You know when a research direction is dead, when a benchmark is being gamed, and when to trade elegance for something that ships this quarter.
Nice to have
- Enough physics or mathematics background to hold a substantive conversation with domain scientists and to understand whether the science is real.
- Hands-on experience applying agents or RL to science, mathematics, code, or other complex-reasoning domains.
- Experience scaling an AI research organization through rapid company growth, including hiring, leveling, and performance management.
- Experience with AI-for-science specifically: simulators, verification, scientific tool use.
- We hold a high technical bar and give people full ownership of their work, from spec to ship to on-call.
- This is an in-person role based in Boston.
- We evaluate on AI research judgment, technical depth, leadership track record, and shipping velocity.
Compensation
- We offer competitive compensation including salary, benefits, and meaningful early-stage equity.
