Models routinely produce derivations that break conservation laws and reach results no working physicist would accept. You bring the subject knowledge to catch these errors, and the tooling to prove them.\n\nThis is a new and growing area for our company, focused on teaching AI to reason correctly rather than plausibly. The work combines deep physics knowledge with strong coding skills: you design, test, and validate complex tasks yourself. Your task and your solution become the ground truth a model is scored against, so accuracy is the entire job.\n\nAdvantages of contracting with us:\n\nYou will be able to choose which projects you want to work on and when.\nYou work on your own schedule, on your own computer, from the comfort of your own home.\nProjects are paid hourly up to $40-$125 USD per hour, with bonuses on high-quality work.\n\nResponsibilities:\n\nDesign complex physics tasks in your area of expertise.\nDefine what a correct answer looks like and the standard a model has to meet.\nTest and validate the task yourself before you submit it.\nWrite a step-by-step solution another researcher could reproduce.\nDesign tasks a model cannot solve by replaying a known result, and flag where its physical reasoning breaks: dimensional and sign errors, invalid approximations, violated conservation laws, unphysical results.\nWork across computational physics, simulation, numerical methods, data analysis, and theoretical modeling.\n\nQualifications:\n\nFluency in English (native or bilingual level).\nAn active research background in physics or a closely related field: advanced graduate student, postdoc, academic researcher, or industry practitioner.\nStrong coding skills. You write Python and work comfortably at a terminal as part of your research, not as a side interest.\nFamiliarity with reproducible or containerized environments such as Docker is a plus.\n\nNote: Payment is made via PayPal.
