We're looking for a Mechanical Engineering - AI Model Evaluator to help train AI models. You'll write hard, verifiable engineering problems drawn from your own specialty, work out the answers yourself, and show us exactly where today's AI systems still fall short of a practicing engineer.

This is a new and fast-growing area for our company, focused on teaching AI to reason like an engineer. The models can already talk fluently about mechanical engineering. What they can't yet do reliably is the actual work: size a component against a real load case, catch the failure mode a spec sheet doesn't mention, read a CAD assembly and tell you what interferes at full travel, or predict what a design change breaks downstream. Your engineering judgment becomes the benchmark those models are measured against.

Responsibilities:

Write challenging, closed-ended problems from your area of expertise, built so that solving them requires real engineering reasoning rather than a lookup

Derive the correct answer, verify it, and write a worked solution showing how you got there

Test your problems against AI systems and sharpen the ones they get right until they challenge the model

Review AI-generated engineering analysis, designs, and technical documentation for correctness and real-world applicability

Review other contributors' problems and solutions for correctness, ambiguity, and rigor

Problems draw on whatever you know best:

Mechanical design and CAD: geometry, clearances, tolerances, mechanisms, and the effect of design changes

Structures and materials: stress, deflection, fatigue, buckling, material selection, and failure analysis

Thermal and fluids: heat transfer,



thermodynamics, HVAC, pumps and piping, and fluid mechanics

Dynamics and controls: vibration, kinematics, rotating machinery, and control systems

Manufacturing: DFM/DFA, process selection, GD&T;, tolerance stack-ups, and cost and quality trade-offs

Advantages of contracting with us:

Choose which projects you work on and when

Work on your own schedule, on your own computer, from the comfort of your own home

Projects are paid hourly up to $40–$125 USD per hour, with bonus rates available on some projects

Qualifications:

2+ years of professional mechanical engineering experience in any specialty: design, product development, manufacturing, thermal, structural, automotive, aerospace, HVAC, robotics, energy, or related fields

Fluency in the tools of your specialty, such as CAD (SolidWorks, Fusion 360, Onshape, Creo, NX, CATIA, or Inventor), FEA/CFD, or MATLAB/Python for engineering analysis

Strong fundamentals across mechanics of materials, dynamics, thermodynamics, heat transfer, fluid mechanics, and manufacturing processes

Able to write a precise, unambiguous technical problem and a transparent worked solution in fluent written English

Meticulous: you check your own work and enjoy finding the edge case that breaks an assumption

A bachelor's degree in mechanical engineering or a related field (completed or in progress)
