Applied Physics

Alignerr

Applied Physics - AI Data Trainer

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 - exposing gaps in their physical reasoning and helping ensure they never violate the principles of conservation of energy, momentum, or anything else your training tells you is non-negotiable.

This is a fully remote, flexible contract role built for researchers and scientists who want high-impact work on their own schedule. No prior AI experience required - just a command of physics that goes all the way down to first principles.

    : Remote
  • Commitment
    : 10-40 hours/week
What You'll Do
  • Design Advanced Physics Problems
    - Craft open-ended, multi-step problems at PhD qualifying exam level, spanning quantum mechanics, electrodynamics, thermodynamics, and classical mechanics
  • Author Gold-Standard Solutions
    - Write rigorous, step-by-step "golden responses" with flawless handling of physical constants, unit conversions, and mathematical derivations
  • Audit AI Reasoning
    - Evaluate AI-generated proofs and simulations for physical consistency, identifying where models hallucinate results or violate first principles
  • Refine Model Behavior
    - Provide structured, expert feedback that improves how AI handles boundary conditions, conservation laws, and physics-informed constraints
  • Document Failure Modes
    - Systematically record where and how AI reasoning breaks down so research teams can address root causes
Who You Are
  • Completed or nearly completed PhD in Applied Physics, Physics, Engineering Physics, or a closely related field
  • Deep mastery across the core pillars: Classical Mechanics, Electrodynamics, Statistical Mechanics, and Quantum Mechanics
  • Exceptional ability to explain complex physical phenomena and mathematical derivations in clear, structured English
  • Uncompromising precision with units, scientific notation, and the logical structure of proofs
  • Self-directed and reliable - comfortable working independently on technical tasks without hand-holding
  • No prior AI or machine learning experience required
Nice to Have
  • Experience with data annotation, scientific dataset evaluation, or quality assurance workflows
  • Proficiency with tools like Python (NumPy/SciPy), MATLAB, or COMSOL
  • Background in research publication, technical writing, or academic instruction
Why Join Us
  • Work on some of the most technically demanding AI projects in existence alongside world-leading research labs
  • Fully remote and asynchronous - work when and where it suits you
  • Freelance autonomy with the structure of meaningful, high-value technical work
  • Rare opportunity to apply your physics expertise beyond academia in a high-impact, forward-looking field
  • Potential for ongoing work and contract extension as new projects launch
