About the Opportunity We're building one of the most rigorous STEM AI training datasets in the industry through the SciCode initiative - a collection of high quality scientific coding tasks used to train and evaluate frontier AI models. As a SciCode Trainer specializing in Physics, you'll directly shape cutting-edge AI research by authoring, implementing, and reviewing complex scientific problems in your field of expertise.

What You'll Do Write scientific problem specifications, one main problem plus at least three sub-problems that logically build toward the main solution Implement verified "golden" solutions in Python with complete unit test coverage Design discriminative test cases that clearly distinguish correct from incorrect model outputs Run QC validation on the Central Task Platform (CTP), covering both structural checks and quality rubrics Iterate on tasks based on QC feedback to meet evaluation criteria across multiple LLM judges Join sync calls for reviews, feedback sessions, and standups during overlap hours Who We're Looking For Required Master's or PhD in Physics,



with solid Python programming skills and hands-on experience in scientific computing Ability to write rigorous, well-posed scientific problems with clear constraints and expected outputs Sharp attention to detail — your work needs to meet strict rubrics for well-posedness, test-case discriminativeness, scientific correctness, and determinism Preferred Prior experience in AI data annotation, research, or scientific writing Familiarity with LLM evaluation frameworks or coding benchmarks Experience with libraries such as NumPy, SciPy, SymPy, or other domain-specific scientific tools Published research or academic project experience in a STEM domain Key Skills: Physics &
