Senior Mechanical Design Engineer
$40-90
/hr
Engineering professionals are needed to keep AI grounded in real physical constraints. These roles span mechanical systems, electrical and power systems, civil and structural infrastructure, robotics and mechatronics, and nuclear engineering. You will evaluate AI-generated engineering solutions for physical feasibility, correct use of engineering principles, and safety reasoning, not just whether the answer looks right. Ideal for practicing engineers, PhD candidates, and engineering researchers. Pay: $64-$98/hr.

Engineering evaluation tasks span mechanical, electrical, civil, chemical, and software engineering disciplines. You'll assess AI-generated design solutions, calculations, and technical explanations for correctness and real-world feasibility. Tasks are self-contained: you might evaluate a structural load calculation, review a circuit diagram for component rating errors, or assess whether a proposed manufacturing process is economically viable. AI engineering outputs often pass superficial scrutiny but contain calculation errors, unsafe assumptions, or design choices that would fail in practice. Tasks always specify the engineering discipline and application context before you accept them, so you can work within your area of expertise. PE certification or equivalent professional engineering experience is a strong advantage for higher-paying tasks.
No. Most roles ask for a relevant engineering degree and real-world or simulation experience, not licensure. A PE can help you qualify for senior review roles but isn't a requirement most platforms screen for.
AI-generated engineering solutions: whether a design satisfies real physical and safety constraints, whether calculations and unit conversions are correct, and whether the reasoning holds up under a second look, not just whether the final number matches.
Yes. These are contract, project-based roles, so most people do them on top of existing work. Check your employer's outside-work or IP-assignment policy if you work with proprietary designs.
This page is showing 439 listings, sourced from 13 platforms: Mercor (103), Mindrift (87), Turing (63), Micro1 (61) and Handshake (37). The most recent one was picked up today. The count moves as platforms post and close roles, so treat it as a snapshot of today rather than a fixed figure.
Most sit between $64 and $98 an hour, with a median of $80, measured across the 308 listings on this page that quote an hourly rate. The highest rate currently posted here is $500 an hour. These are the figures the platforms published, not our estimates, and the rate you are offered depends on how you do in that platform's assessment.
Both appear here. 26 listings pay per task or per project rather than by the hour, and the rest quote an hourly rate. Per-task work suits people who are fast and accurate, since your effective hourly rate depends on how long each unit takes you.
3 roles on this page are salaried rather than contract, quoting annual or monthly pay. The remainder are independent contractor listings you can hold alongside other work.
Mercor (103), Mindrift (87), Turing (63), Micro1 (61) and Handshake (37). No single one dominates this category, so it is worth holding accounts on more than one. Most contracts allow you to work through several platforms at the same time.
