Mercor; India; Remote; INR 9,055,000 - 16,169,000; Full time

Job summary

Mercor is seeking mechanical engineers to join a standing pool for AI training and evaluation work. This is a remote, independent contractor listing that stays open per field and is activated when a matching project arises.

New projects start on short notice; researchers use your design judgments to grade models. Past rates have ranged from $70 to $125 per hour, with pay per project by scope and depth.

Qualifications

• A degree in mechanical engineering, with professional design or analysis experience.
• Clear written communication is essential for explaining your reasoning.
• Comfort with ambiguous tasks and willingness to flag unclear instructions.

Responsibilities

• Write a design problem from your prior work, including loads, constraints and tolerances, and reference answer for grading.
• Grade model-written analyses, verify correct free body diagrams and applicable safety factors.
• Flag where a model’s design matches calculations but may fail practically due to manufacturability, wear, or thermal expansion.

Education

Bachelor's degree in Mechanical Engineering

Job description

Mechanical Engineering ExpertCompany: MercorCompensation: $70Commitment: Talent networkLocation: RemoteReferral Link: https://t.mercor.com/UN47a

The research teams behind the best-known AI models come to Mercor for mechanical engineering judgment they can't generate on their own.

Your standards and expertise become the rubric that frontier AI is graded against.

This is a standing listing for mechanical engineers who want AI training and evaluation work, not a specific job opening.

It stays open whether or not a matching project is running this week.

New projects start on short notice, so instead of posting and pulling a listing each time, we keep one open per field and draw from it when one begins.

What the work looks like

• Writing a design problem from work you have done, with the loads, the constraints, and the tolerances, plus the reference answer a model's attempt gets graded against
• Grading model-written analysis: whether the free body diagram is right, whether the failure mode considered is the governing one, whether the safety factor is applied to the right quantity
• Flagging where a model's design satisfies the calculation and fails in practice, given manufacturability, assembly, wear, or thermal expansion

Past rates have run $70 to $125 an hour, set per project by scope and depth.

What we're looking for

• A degree in mechanical engineering, with professional design or analysis experience
• Clear written communication, since most of the work involves explaining your reasoning
• Comfort with ambiguous tasks, and willingness to flag unclear instructions

Where you trained matters less than whether you have had a design of yours built, and learned what it did once it was.

How it works

We verify your background and add you to the mechanical engineering pool. When a project needs mechanical engineering expertise, we invite matching people from the pool to that specific listing. It names the rate, the hours, and the client, and any hiring decision is made there.

What to expect

This listing does not accept or reject candidates, so you will not get a decision on it.

We reach out when a project matches your background.

Depending on what our clients are running, that can be within a week or several months.

Finishing the domain expert interview and joining every network you qualify for both improve your odds of being matched.

You only need to sign up once to be eligible across all of them.

We consider all qualified applicants without regard to legally protected characteristics and provide reasonable accommodations upon request.

Contract and Payment Terms

You will be engaged as an independent contractor.

This is a fully remote role that can be completed on your own schedule.

Projects can be extended, shortened, or concluded early depending on needs and performance.

Your work at Mercor will not involve access to confidential or proprietary information from any employer, client, or institution.

Payments are weekly on Stripe or Wise based on services rendered.

Please note: We are unable to support H1-B or STEM OPT candidates at this time.

About Mercor

Mercor partners with leading AI labs and enterprises to train frontier models using human expertise.

You will work on projects that focus on training and enhancing AI systems.

You will be paid competitively, collaborate with leading researchers, and help shape the next generation of AI systems in your area of expertise.
