Physics Problem Evaluator

Claru bands its desk-based work by how much judgement a task needs. This listing sits in the top band at $55-$100/hr, alongside its RLHF evaluation, medical and 3D vision annotation and red-teaming roles, all of which expect graduate-level or professional depth in the subject and the ability to justify a score in writing. Its entry-tier text labeling sits at $20-$35/hr for comparison.

Batches. Claru describes this work as asynchronous with no scheduled hours and no meetings: you claim a batch, complete it and submit. There is no guarantee a new batch is waiting when you finish one, so treat it as recurring project income rather than a fixed weekly wage.

Yes. Every listing on claru.ai/jobs shows its hourly band on the card and again on the role page, so you can compare a $20-$35/hr labeling role against a $55-$100/hr evaluation role without creating an account first.

Through agreement scoring and review. Its evaluation roles set a target for how closely your scores track other annotators, and disagreements with reviewers are resolved in an async comment thread you are expected to answer within a day. Consistently strong scores are what unlock the senior and lead tracks Claru mentions in its listings.

For the top pay tiers, a PhD or current enrollment is usually expected. But the domain assessment is what decides it: if you can solve the problems, the degree becomes secondary.

Usually not. Work runs in campaigns, like training a model specifically on quantum mechanics, that might last a few weeks. Treat it as a high-paying fellowship or grant rather than a permanent daily job.

Tasks here are scoped to STEM, not generic labeling. As a Physics Problem Evaluator, expect to draw on real domain judgment (evaluating outputs, correcting errors, or providing expert reasoning specific to STEM) rather than following a one-size-fits-all rubric. If you don't have hands-on STEM background, this is likely not the right listing to start with.

Expert is named directly in the listing. If you don't have hands-on experience with this, expect the screening process to test for it directly rather than accepting adjacent experience as a substitute.

This listing is posted at $55–$100/hr, an hourly rate. The range reflects experience level and negotiated terms, not a placeholder, so where you land in it depends on your background and the assessment. Pay can change between when we last checked the listing and when you apply, so confirm the current number on the platform's own application page before committing time.

You'll be taken to Claru's external site to complete your application there. This listing links through a referral, but the process is identical to applying directly; the link just routes you correctly. Create an account on their site and follow their onboarding steps.

Claru is the contributor-facing brand of Reka AI, which collects human data for frontier AI labs across text, vision, video and robotics. Its board splits into regional video capture work and desk-based annotation and evaluation, and the apply link on this page is an affiliate link that does not change your pay or what you are offered.
