The work

Create realistic mechanical engineering problems based on parts, assemblies, and analyses that have been manufactured, tested, or approved. Review AI-generated technical content and give clear, structured feedback to help improve how AI systems handle engineering work.

• Check models, drawings, tolerances, calculations, and finite element analysis results for accuracy and sound reasoning.
• Assess whether designs are manufacturable, practical, defensible, and aligned with engineering standards and practice.
• Judge whether technical work is clear and robust enough for another reviewer to dimension against.

What it pays and takes

• Pay: Up to $100 per hour for qualifying work.
• Work arrangement: Flexible, part-time contract work with no set schedule or minimum-hour requirement. Work at your own pace alongside employment or studies.
• Location: Open to candidates based in the United States.
• Experience: Hands‑on mechanical engineering experience, or engineering studies that include work that has been manufactured, tested, or approved.
• Education: A BS, MS, or PhD in Mechanical Engineering or a closely related engineering discipline.
• Technical skills: Depth in at least one of these areas: parametric solid modeling built to tolerance, GD&T drawing interpretation, standards‑based calculations, or FEA validated against hand calculations.
• Other requirements: Strong written communication, attention to detail, clear explanations of complex engineering concepts, and the ability to work independently in a remote, asynchronous setting.
• Helpful experience: SolidWorks, Creo, NX, CATIA, Inventor, Fusion 360, ANSYS, Abaqus, Nastran, MATLAB, or comparable tools. Manufacturing‑ready work involving machining, sheet metal, casting, injection molding, or additive manufacturing is also useful.

About AI training work

AI training work uses human examples and reviews to help improve how AI systems respond. Mechanical engineering expertise helps reviewers assess whether technical answers are accurate, practical, and well supported.
