About this role

From the Mercor listing

We're looking for experienced mechanical engineers to join a high-impact quality assurance and review initiative focused on advancing technical content across engineering domains. In this role, you'll apply your domain expertise to evaluate, validate, and improve the accuracy and rigor of mechanical engineering material—ensuring it meets the highest standards of correctness and clarity.

This is a flexible, remote engagement well-suited to practicing engineers, researchers, and recent graduates with strong fundamentals who want to apply their knowledge in a meaningful, intellectually engaging way.

About the Role

We're looking for experienced mechanical engineers to join a high-impact quality assurance and review initiative focused on advancing technical content across engineering domains. In this role, you'll apply your domain expertise to evaluate, validate, and improve the accuracy and rigor of mechanical engineering material—ensuring it meets the highest standards of correctness and clarity. This is a flexible, remote engagement well-suited to practicing engineers, researchers, and recent graduates with strong fundamentals who want to apply their knowledge in a meaningful, intellectually engaging way.

What You'll Do

  • Review technical problems, solutions, and explanations within mechanical engineering for accuracy, completeness, and methodological soundness
  • Identify errors, ambiguities, or gaps in reasoning and provide clear, well-justified feedback
  • Apply consistent evaluation standards across a range of mechanical engineering subdomains (e.g., statics and dynamics, thermodynamics, fluid mechanics, heat transfer, mechanics of materials, machine design)
  • Calibrate your judgments against established quality benchmarks to ensure consistency and reliability
  • Contribute to maintaining a high bar for technical quality across the body of work you review

What We're Looking For

  • A degree in Mechanical Engineering or a closely related field (Bachelor's required; Master's or PhD a plus)
  • Strong command of core mechanical engineering fundamentals and the ability to work problems rigorously from first principles
  • Sharp attention to detail and the ability to spot subtle technical errors
  • Clear written communication and the ability to articulate why something is correct or incorrect
  • Comfort working independently and applying structured evaluation criteria consistently
  • Prior experience in technical review, grading, tutoring, or QA is a plus but not required We consider all qualified applicants without regard to legally protected characteristics and provide reasonable accommodations upon request.

Common questions

Does Mercor's application require an on-camera interview?

Yes. You record a video interview with an AI interviewer that asks about your resume, and clients watch it before they hire, so plan to be on camera.

Does it cost money to apply to Mercor?

No, applying to and joining Mercor is free. Mercor charges the client a fee on top of your rate. If anyone asks you to pay to join, treat it as a scam.

Is research-level AI training steady work?

Usually not. Work comes in projects, such as training a model on quantum mechanics, that can last a few weeks. Plan for it like a short fellowship.

Is research-level AI training the same as data labeling?

It's closer to academic research. You write or check proofs, solve advanced problems and test the logic behind a model's step-by-step reasoning in your field.

What does STEM work look like for a Mechanical Engineer Expert?

You check AI answers to STEM questions, correct their errors and write expert reasoning. As a Mechanical Engineer Expert, you're hired for that judgment, so hands-on STEM experience matters.

What specific skills does this listing call for?

Coding is named directly in the listing. If you don't have hands-on experience with this, expect the screening to test for it.

How much does this specific role pay?

This listing is posted at $90/hr, an hourly rate. Pay can change after we check the listing, so confirm the rate on the platform's application page.

What happens when I click Apply on this listing?

Apply opens Mercor's site, where you create an account and follow its sign-up steps.

Is a PhD required?

For this role, yes, or similar professional depth, and the assessment checks it. PhD candidates and people with published research have qualified without the degree.

How soon will I start working after applying to Mercor?

Usually after a few weeks. Applying puts you in Mercor's pool of candidates, and you start once a client, such as an AI lab, picks your profile.
