Physicist, Part-Time AI Physics Problem Solving - Remote (United States)

• $100–$200 per hour• 100% remote• Part-time• Under 20 hours a week, you choose when Work on the cutting edge of AI, on your own schedule, and get paid for the physics expertise you already have. The AI systems everyone is talking about are trained and tested by real physicists. The teams building them need physicists who can create difficult, realistic physics problems, judge whether an AI's solution is correct, write the rigorous derivation a physicist would give, and explain exactly where the reasoning falls short. Your judgment helps shape the next generation of AI models' ability to reason about science. This is that work, done remotely around your current research or job. What you'll do• Create advanced physics problems with clear assumptions, approximations and boundary conditions• Review AI-generated solutions for technical accuracy, dimensional consistency and reproducibility, using SymPy, Python or Jupyter when relevant• Write rigorous step-by-step derivations in LaTeX, including intermediate reasoning, special cases and final results• Describe any unclear or incorrect reasoning, propose well-supported clarifications, and apply reviewer feedback without sacrificing technical accuracy Why this is worth your time• Get paid $100–$200 an hour to build real AI skills, on top of your current job• Work directly with frontier AI tools and see how they are built, tested and improved, experience most physicists will not have for years• Build a career edge for what comes next: AI is reshaping physics and scientific research, and the people who understand it from the inside will lead that change• Fully remote and flexible, no fixed shifts, no commute Who this is for• A PhD in physics; alternatively, advanced-stage PhD candidacy or experience conducting postdoctoral research in physics• Strong analytical ability, clear technical writing, and professional fluency in English• Two to five recent publications representative of your work, with an accessible arXiv or DOI record for each, and working knowledge of LaTeX, SymPy, Python and Jupyter• No AI experience needed. You bring the expertise; we bring the training on the tools.
