About the Role

What if your deep expertise in physics could directly shape how AI understands the fundamental laws of the universe? We're looking for PhD-level Applied Physicists to stress-test cutting-edge AI models — probing their reasoning, exposing their blind spots, and helping ensure they respect principles like conservation of energy, quantum mechanics, and electrodynamics.

This is a fully remote, flexible contract role built for researchers and domain experts who want to do meaningful, high-impact work on their own schedule. 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 at PhD qualifying exam level, requiring multi-step logical reasoning and precise mathematical derivation across topics like quantum mechanics, thermodynamics, and electrodynamics
  • Author Ground-Truth Solutions — Write rigorous, step-by-step "golden responses" where every physical constant, unit conversion, and logical step is exactly right
  • Audit AI Reasoning — Evaluate AI-generated proofs and simulations for physical consistency, identifying where models "hallucinate" physics that violates first principles
  • Refine Model Behaviour — Provide structured, expert feedback that improves an AI's ability to apply physics-informed reasoning — including boundary conditions, symmetry arguments, and conservation laws
  • Work Independently — Complete task-based assignments fully asynchronously, on your own schedule

Who You Are

  • Holds a PhD (completed or near completion) in Applied Physics, Physics, Engineering Physics, or a closely related field
  • Deep command of the core pillars: Classical Mechanics, Electrodynamics, Statistical Mechanics, and Quantum Mechanics
  • Exceptional analytical writing ability — you can explain a complex derivation clearly, precisely, and in structured English
  • Uncompromising attention to detail when it comes to units, scientific notation, and proof logic
  • Self-motivated and reliable when working independently without close supervision
  • No prior AI or machine learning experience required

Nice to Have

  • Experience with data annotation, scientific dataset evaluation, or quality assurance for research outputs
  • Proficiency with computational tools such as Python (NumPy/SciPy), MATLAB, or COMSOL
  • Background in physics education, academic publishing, or technical writing
  • Familiarity with AI tools or large language models as an end user

Why Join Us

  • Work on cutting-edge 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
  • Make a direct, lasting impact on how AI reasons about the physical world
  • Potential for ongoing work and contract extension as new projects launch
