Physics Expert (PhD or Master's)

Physics Experts (PhD or Master's), Are You There?

Athyna is building Latin America's largest network of Physics PhDs and Master's researchers to work directly on frontier AI post-training with leading AI labs and Fortune 500 companies.

You'll design evaluation frameworks, stress-test model performance, conduct red-teaming exercises, and help refine AI systems for real-world deployment. Projects range from targeted evaluations to ongoing model improvement work, with flexible engagement options: full-time, part-time, or project-based—depending on client needs and your availability.

This is hands-on research work that directly shapes how advanced AI systems perform in production.

In Your Day-To-Day, You Will

• Create and review advanced physics problems that test AI reasoning depth.
• Evaluate AI-generated solutions for correctness, rigor, and clarity.
• Identify logical gaps, incorrect assumptions, or incomplete derivations.
• Produce clear, well-reasoned reference solutions when needed.
• Maintain high standards of scientific accuracy and problem difficulty.

Skills You Have

• PhD or Master's degree in Physics or a closely related field.
• Deep understanding of theoretical and/or experimental physics.
• Strong ability to reason quantitatively and analytically.
• Experience explaining complex physical concepts in writing.

Skills That Will Make You Stand Out

• Experience with Olympiad-style or research-level problem solving.
• Familiarity with AI evaluation or scientific benchmarking.
• Proficiency with LaTeX or structured mathematical writing.
• Experience applying physics expertise to AI or computational systems.

We're currently accepting applications, so if this role sounds like you, let us know. People often hesitate to apply unless they feel fully confident—don't let that hold you back. If this work excites you, we'd love to hear from you.
