Job description

Applied Physics (AI Training)

About The Role

What if your deep expertise in physics could directly shape how AI reasons about the physical world? We're looking for PhD-level Applied Physicists to stress-test cutting-edge Large Language Models — probing their understanding of quantum mechanics, electromagnetism, thermodynamics, and more — and help ensure that AI reasoning never violates the fundamental laws of the universe.

This is a fully remote, flexible contract role. No prior AI experience required — just mastery of physics and a rigorous analytical mind.

• Organization: Alignerr
• Type: Hourly Contract
• Location: Remote
• Commitment: 10–40 hours/week

What You'll Do

• Design Advanced Physics Problems — Craft complex, open-ended problems equivalent to PhD qualifying exam level, requiring multi-step reasoning and mathematical derivation across core physics domains
• Author Ground-Truth Solutions — Develop rigorous, step-by-step "golden responses" with flawless physical constants, unit conversions, and logical flow
• Audit AI Reasoning — Evaluate AI-generated simulations, proofs, and derivations for physical consistency, identifying where models "hallucinate" physics that violates first principles
• Refine Model Thinking — Provide structured, expert feedback to improve AI performance on physics-informed reasoning, including boundary conditions, conservation laws, and symmetry constraints
• Work Independently — Complete task-based assignments asynchronously, fully on your own schedule

Who You Are

• PhD completed or in final stages in Applied Physics, Physics, Engineering Physics, or a closely related field
• Deep mastery of core physics pillars: Classical Mechanics, Electrodynamics, Statistical Mechanics, and Quantum Mechanics
• Exceptional ability to communicate complex physical phenomena and mathematical derivations in clear, structured English
• Uncompromising attention to detail — you catch unit errors, sign mistakes, and flawed assumptions instinctively
• Self-motivated and reliable when working independently
• No prior AI or machine learning experience required

Nice to Have

• Experience with data annotation, dataset quality evaluation, or scientific benchmarking
• Proficiency with computational tools such as Python (NumPy/SciPy), MATLAB, or COMSOL
• Background in research publication, technical writing, or academic instruction
• Familiarity with AI tools or language model evaluation as an end user

Why Join Us

• Work on high-impact AI projects alongside world-leading research labs
• Fully remote and flexible — work when and where it suits you
• Freelance autonomy with the structure of meaningful, intellectually stimulating work
• Apply your PhD-level expertise in a novel, high-demand field at the frontier of AI development
• Potential for ongoing work and contract extension as new projects launch
