FirstPrinciples Research Fellow

As a Research Fellow, you will own a well-scoped research direction that contributes directly to the AI Physicist's ability to reason about physics.

• Improve Theo's ability to produce scientifically sound, high-quality outputs in 2026
• Introduce new ideas, methods, and approaches that meaningfully shift system performance
• Bring deep domain expertise (PhD+ level) in one or more targeted research areas

This role contributes to building an autonomous AI Physicist that can explore theoretical frameworks, reason across disciplines, and generate novel insights to tackle the deepest unsolved problems in physics, accelerating progress on fundamental questions about the nature of reality.

• PhD or postdoctoral researchers in Computer Science, Machine Learning, Theoretical Physics, or a closely related field
• Track record of research in model architectures, representation learning, or reasoning systems (CS/ML path) OR mathematical, physical, or formal reasoning applied to fundamental problems (physics path)
• Demonstrated ability to translate abstract theory into testable computational systems
• Comfortable working across disciplinary boundaries and operating independently

12 month engagement with full-time or equivalent commitment, fully remote, fixed stipend for the full term (no specific salary mentioned).
