Job summary

DataAnnotation is seeking a Physicist to evaluate AI reasoning across mechanics, E&M, quantum, and thermodynamics, and to write solutions with the care of a problem-set grader.

You’ll craft problems, review AI solutions for dimensional errors and skipped steps, and deliver gold-standard solutions with clear, step-by-step physics explanations. Flexible, remote, and project-based work. Ideal for researchers who want to apply physics to AI evaluation.

Qualifications

• Graduate-level physics background or equivalent research experience.
• Comfort solving problems across at least two core areas of physics.
• Clear written English; explanations should be training signals.

Responsibilities

• Craft problems exposing weak physical reasoning across mechanics to graduate-level theory.
• Review AI solutions for dimensional errors and skipped steps and rate reasoning.
• Write gold-standard solutions with step-by-step physics explanations.

Job description

Models can recite physics and still get it wrong: dimensional errors, misapplied approximations, and derivations that skip the step where the physics actually happens.

As a Physicist you'll evaluate AI reasoning across mechanics, E&M, quantum, and thermodynamics, and write solutions with the care of a good problem-set grader.

What you’ll actually do

• Craft problems that expose weak physical reasoning, from undergraduate mechanics to graduate-level theory.
• Review AI solutions for dimensional errors, misapplied approximations, and skipped steps, and rate the reasoning.
• Write the gold-standard solution when the model falls short, showing the physics clearly at every step.

Roles this fits

Common backgrounds: Physicist, Research Scientist.

What we look for

• Graduate-level physics background or equivalent research experience.
• Comfort working problems across at least two core areas of physics.
• Clear written English: your explanations are the training signal.
• No degree required. We care about what you can do, not where you learned it.
