About AI Model Evaluation

AI training depends on expert human judgment. Contributors review model outputs, compare competing answers, identify errors and uncertainty, and provide the reasoning that helps AI systems become more accurate and reliable. This work offers a flexible, remote way to contribute to cutting-edge technology.

The Physics Model Evaluation Expert Role

OpenTrain is seeking a Physics Model Evaluation Expert to provide senior-level scientific judgment for training next-generation AI systems. You will assess competing physics reasoning, explain when one approach is stronger and under which assumptions, and produce defensible evaluations for review by fellow physicists.

The work centers on nuanced expert adjudication, calibrated confidence, and understanding the limits of approximations across advanced physics subfields. Prior AI experience is not required.

• Subject focus: Advanced Physics Model Evaluation
• Work type: Text-based evaluation and rating
• Classification: Entry level in the project listing; PhD-level expertise and research leadership are required
• Language: English

What You'll Do

You will evaluate technically sophisticated physics content and clearly communicate the basis for each judgment. Your analyses should distinguish established conclusions from uncertainty, unresolved questions, and open problems.

• Adjudicate contested physics arguments, solutions, and interpretations within your active subfield.
• Compare alternative approaches and explain their relative strengths, assumptions, applicable regimes, and breaking points.
• Develop criteria for judging the robustness and validity of technical physics work.
• Identify unresolved questions and distinguish established conclusions from uncertainty or open problems.
• Draft rigorous written evaluations suitable for review by senior physicists.
• Use LaTeX, SymPy, Python, and Jupyter as needed to verify or contrast technical claims.

Required Qualifications

This role requires demonstrated scholarly expertise in a defined, active physics research subfield. Candidates should be able to make nuanced, well-reasoned judgments and produce rigorous written evaluations for technically sophisticated readers.

• PhD in physics with demonstrated expertise and scholarly impact in an active research subfield.
• Current or former senior academic, principal investigator, research group leader, or equivalent research leadership experience.
• Representative recent publications and experience supervising doctoral students or postdoctoral researchers.
• Exceptional written communication and calibrated scientific judgment.
• Ability to explain assumptions, applicable regimes, approximation limits, and the strengths or weaknesses of competing arguments.
• Working proficiency with relevant tools such as LaTeX, SymPy, Python, and Jupyter.

Relevant Physics Backgrounds

Relevant expertise may come from one or more of the following areas:

• High-energy physics
• Mathematical physics
