About the Role

What if your PhD-level expertise in physics could directly shape how AI understands the physical world? We're looking for Applied Physics Specialists to rigorously challenge large language models — exposing gaps in their reasoning, catching violations of fundamental physical laws, and helping build AI that truly understands how the universe works.

This is a fully remote, flexible contract role designed for practicing physicists and advanced PhD candidates who want to apply their expertise to one of the most consequential problems in modern AI.

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

What You'll Do

  • Design PhD-Level Problems: Craft advanced, open-ended physics problems — equivalent in depth and rigor to qualifying exam questions — that require multi-step logical reasoning and complex mathematical derivation
  • Author Gold-Standard Solutions: Write meticulous, step-by-step solutions that serve as ground-truth references, with flawless handling of physical constants, units, and derivation logic
  • Audit AI Reasoning: Evaluate AI-generated proofs, simulations, and explanations for physical consistency — identifying where models "hallucinate" physics that violates first principles
  • Refine Model Behavior: Provide structured, expert feedback that improves how AI models handle physics-informed reasoning, including boundary conditions, conservation laws, and dimensional analysis
  • Work Across Core Domains: Apply your knowledge across quantum mechanics, electrodynamics, classical mechanics, thermodynamics, and statistical mechanics

Who You Are

  • Holds a PhD (completed or near completion) in Applied Physics, Physics, Engineering Physics, or a closely related field
  • Deep, working mastery of the four pillars of physics: Classical Mechanics, Electrodynamics, Statistical Mechanics, and Quantum Mechanics
  • Exceptional analytical writing skills — able to explain complex phenomena and derivations in clear, structured English
  • Uncompromising attention to detail when it comes to units, notation, dimensional consistency, and logical flow
  • Self-directed and comfortable working independently on complex, open-ended tasks
  • No prior AI experience required — your physics expertise is what matters

Nice to Have

  • Prior experience with data annotation, scientific dataset evaluation, or quality assurance for technical content
  • Proficiency with tools such as MATLAB, COMSOL, Python (NumPy/SciPy), or similar computational physics environments
  • Research background involving simulation, modeling, or applied theoretical work

Why Join Us

  • Work on high-impact AI projects in collaboration with leading AI research labs
  • Fully remote and asynchronous — work when and where it suits you
  • Freelance autonomy with the structure of meaningful, expert-level work
  • Direct exposure to how frontier LLMs are trained and evaluated
  • Contribute to ensuring AI systems respect the fundamental laws of the physical world
  • Potential for ongoing work and contract extension as new projects launch
