Verification/testing Engineer
$40 - $125 per hourTemporary
DataAnnotation
Location: Remote · Type: Independent contractor · Hours: Flexible hours · Payouts: We’re looking for an experienced Validation Engineer 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.
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.
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.
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.
Validation Engineer, Test Engineer, Reliability Engineer.
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.
- A bachelor’s degree in mechanical engineering or a related field (completed or in progress).
- some make it their full-time income.
Flexible, remote, and always project-available.
Apply, pass the qualification assessment, then pick up paid projects whenever you want and get paid weekly.
