The work

You will create realistic computational physical-science tasks for AI models and define what a correct solution must include. You will also assess whether generated technical work is accurate, reproducible, and physically sound.

The work combines physical-science expertise with Python and computational research. You will give clear, technically grounded judgments on model outputs.

  • Create task instructions that test calculations, code, simulations, models, and technical analysis.
  • Set up reproducible environments, reference solutions, evaluation criteria, rubrics, and graders.
  • Review AI-generated Python code, calculations, simulations, models, and other technical deliverables.
  • Find invalid assumptions, numerical errors, physically impossible results, incorrect methods, and reproducibility failures.
  • Set objective standards for correct solutions and explain your technical judgments.

Requirements

This is expert-level contract work for people with prior paid experience training, evaluating, benchmarking, or improving AI systems on scientific or technical tasks.

  • Time: Less than 20 hours per week.
  • Language: Professional fluency in English.
  • Experience: Expert-level experience with AI training or model evaluation involving scientific or technical content.
  • Python: Strong practical proficiency with Python.
  • Science: Deep expertise in at least one physical-science specialization.
  • Research: Hands-on experience with computational modeling, simulation, numerical analysis, data analysis, or reproducible research.
  • Evidence: Public technical work such as computational publications, preprints, public simulation or analysis code, research profiles, open-source contributions, reproducible notebooks, models, datasets, benchmarks, or experiments.
  • Experience: Mid-Senior level
  • Skills: Physics, AI Training, Programming Skills
