Mechanical Engineering Expert (Remote, Part-Time)
Listing checked September 16, 2026 · pay as published by Mercor
Overview
AI research teams rely on Mercor for mechanical engineering judgment that models cannot generate alone. Your design standards and analysis habits become the rubric that grades frontier AI. Mercor keeps a standing listing for mechanical engineers who want AI training and evaluation work, even when no project is active. When a project starts, matching engineers from the pool receive an invite that names the rate, hours, and client.
What You'll Do5
- 1Write design problems from work you have done, covering loads, constraints, and tolerances, then supply a reference answer that anchors the model's score.
- 2Grade model-written analysis, checking the free body diagram, the governing failure mode, and whether the safety factor applies to the right quantity.
- 3Identify designs that pass the calculation but fail in practice because of manufacturability, assembly, wear, or thermal expansion.
- 4Explain your reasoning in writing so project leads can follow the basis for each score.
- 5Flag unclear task instructions and request missing constraints before starting an evaluation.
Requirements5
- 1Degree in mechanical engineering plus professional experience in design or analysis.
- 2A track record of designs that moved from concept to build, with lessons from how they performed.
- 3Clear written communication, because most tasks require you to justify your judgment.
- 4Comfort with ambiguous tasks and willingness to call out instructions that lack detail.
- 5Working knowledge of loads, constraints, tolerances, failure modes, and safety factors.
Who Should Apply
Mechanical engineers with hands-on design or analysis experience fit this pool best. You have seen a design get built and learned what happened after assembly, wear, or thermal cycling. The role suits people who can write precise explanations and who notice when a task brief leaves out a critical constraint. Candidates who only hold a degree without professional design work often score low, and applicants who give vague answers in the AI interview struggle to match. Another common rejection reason is failing to show how your judgment applies to real hardware rather than textbook problems.
Salary Insight
Past projects paid between $70 and $125 an hour, with Mercor setting each rate by scope and depth. Complex grading work or design problem writing tends to land at the higher end, while shorter reviews sit lower. This range matches senior contract mechanical engineering work and specialized AI evaluation, not entry-level annotation.

Application Tip
When you apply, attach a short work sample that names a design you built, the loads, constraints, and tolerances, and the outcome after manufacturing. In the AI interview, walk through one failure mode you caught in a model's analysis and how you set the safety factor. That evidence raises your fit score more than listing tools.

Mercor
VerifiedEngineering Expert - Remote AI Evaluation
Mercor supports research teams behind well-known AI models by supplying engineering judgment that models cannot generate on their own. Your design standards and analysis habits become the rubric used to grade a model's engineering output. The company keeps a standing, part-time listing for engineers who want AI evaluation and training work, not a single opening. Projects can start with short notice, so Mercor draws from this pool when a client needs a discipline such as structural engineering, mechanical engineering, or electrical engineering. Past engineering projects posted at $60.00 to $125.00 per hour.
Mercor
VerifiedElectrical Engineering Expert - Remote Part-Time
Mercor maintains a standing roster of electrical engineers to support AI research teams that need human judgment on hardware problems. The listing does not tie to one active project. Instead, it lets you join a pool that Mercor draws from when a client needs help writing problems, grading model output, or evaluating design choices. Work can involve circuit design review, systems analysis, noise and stability margins, and checks for whether a model's answer survives real board conditions like parasitics or tolerance stack-up. Rates for past projects ranged from $70 to $120 per hour, with scope and depth setting the final number.
Handshake AI
VerifiedMechanical Engineering Expert - Remote Contract
Handshake AI seeks practicing mechanical engineers to join a part-time, project-based fellowship that improves how AI models handle engineering reasoning. You will write expert problems and judge AI output across parametric solid modeling, GD&T drawing interpretation, standards-based design calculations, and FEA checked against hand calculations. Work runs remote and asynchronous, so you set your own hours and complete tasks alongside a current job or degree. A United States location requirement applies. The company pays $120 per hour for contributions.
Mercor
VerifiedSoftware Engineer Expert (Remote) Part-Time
Mercor keeps a standing pool of software engineers who help grade and train frontier AI models. The work is part-time and remote, and projects span frontend, backend, mobile, embedded, DevOps, QA, and security engineering. Assignments range from writing original engineering problems with reference answers to reviewing model-written code for edge cases, complexity, and production failure modes. Past software engineering projects on Mercor paid between $70 and $150 per hour, with scope and depth setting the exact rate.
Mercor
VerifiedMechanical Engineer - AI Lab Project (US Remote)
Mercor pairs seasoned mechanical engineers with a frontier AI lab's GenAI group for a remote, W-2 role through Cincinnatus LLC. You will judge how well large language models handle real engineering problems, from FEA and CFD analyses to drawings, tolerances, and design reviews. The work centers on quality review, instruction specs, worked reference solutions, and benchmark sets that test genuine domain reasoning. Expect a 2 to 3 month initial engagement at 40 hours per week, with a strong chance of extension if the collaboration goes well. Pay runs $60 to $90 per hour.
AfterQuery
VerifiedMechanical Hardware Design Engineer - Remote Contract
AfterQuery seeks senior mechanical and hardware design experts for a research cohort that tests how frontier AI models handle hard, real-world problems. You will design technical scenarios and reference solutions across CAD, RTL/HDL, and robotics, then judge model outputs for correctness and depth. The work runs on a contract basis at about four hours per week, with remote and asynchronous scheduling. The focus stays on evaluation and research, not production engineering. Your job centers on defining what counts as a correct or excellent answer in your domain.
