How this pay compares
At $72/hr, this role pays more than 36% of the 207 open engineering roles with a listed pay range, below the median of $80.
Open engineering roles that ask for a PhD have a median of $94/hr (34 roles).
Among platforms with 10 or more priced engineering roles, Mercor has the highest median ($88/hr across 35 roles) and micro1 the lowest ($60/hr across 28).
OpenTrain AI roles that closed since late October stayed listed a median of 31 days (122 roles). OpenTrain AI posted this one 2 days ago.
Computed from 2,746 open roles we track across Mercor, micro1, Handshake AI, Alignerr, Appen and OpenTrain AI, refreshed daily. Midpoints of listed ranges; “up to” ceilings are left out of medians.

The work
You will help improve AI systems by creating realistic mechanical engineering problems and reviewing their answers. Your feedback will focus on whether technical work is accurate, practical, manufacturable, clear, and consistent with engineering practice.
- Create engineering scenarios based on work that has been manufactured, tested, or approved.
- Review AI-generated responses, models, drawings, tolerances, calculations, and FEA results.
- Assess technical accuracy, practical feasibility, manufacturability, standards alignment, and defensibility.
- Decide whether technical work is clear enough for another reviewer to dimension against.
- Write structured feedback that helps improve AI model performance.
What it pays and takes
This is remote, part-time contract work with no set schedule or minimum-hour requirement.
- Pay: Up to $72 per hour.
- Location: Open to applicants based in Canada.
- Language: Fluent English.
- Education: A BS, MS, or PhD in Mechanical Engineering or a closely related engineering discipline.
- Experience: Hands-on mechanical engineering experience, or experience as a student producing a part, assembly, or analysis used by others.
- Technical depth in parametric solid modeling, GD&T drawing interpretation, standards-based mechanical calculations, or FEA validated against hand calculations.
- Strong written communication, attention to detail, and the ability to explain complex engineering concepts clearly.
- Able to work independently in a remote, asynchronous environment.
- Current bachelor's students must have relevant internship experience.
Helpful experience
Experience with common mechanical design, simulation, and analysis tools is useful. Additional value comes from creating manufacturing-ready work or working in product design, manufacturing, aerospace, defense, or automotive settings.
- Tools such as SolidWorks, Creo, NX, CATIA, Inventor, Fusion 360, ANSYS, Abaqus, Nastran, or MATLAB.
- Manufacturing-ready drawings or models for machining, sheet metal, casting, injection molding, or additive manufacturing.
- Experience with a manufacturer, product design firm, aerospace or defense contractor, or automotive supplier.
