Description
We're looking for an experienced 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 75–125 USD per hour, with bonus rates available on some projects
Note:
Payment is made via PayPal. We will never ask for any money from you. PayPal will handle any currency conversions from USD. Only applicants in the United States, Canada, and the United Kingdom will be considered for this role. This is an independent contractor position.
Requirements
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 clear 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)
