Biophysicist - AI Trainer

DataAnnotation; Minnesota; Remote; USD 55,000 - 172,000; Full time

Job summary

DataAnnotation is seeking a Physicist to evaluate AI reasoning across mechanics, E&M, quantum, and thermodynamics, and to craft clear, step-by-step solutions that demonstrate correct physics.

Ideal candidates have a graduate-level physics background or equivalent research experience and can explain complex ideas in clear English. The role is remote, flexible, and project-based, with compensation tied to task difficulty.

Qualifications

• 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.

Responsibilities

• 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.

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.

Compensation

Up to $40 – $125+/hr depending on task difficulty and specialization. Many contributors add $10k–$100k+ a year; some make it their full-time income.
