Mechanical Engineering AI Trainer

About the Role

We're partnering with the world's leading AI research labs to build smarter, more technically rigorous AI models - and we need mechanical engineers to help make it happen.

As a Mechanical Engineering AI Trainer, you'll put your deep domain knowledge to work by designing complex engineering problems, authoring authoritative solutions, and auditing AI reasoning across fluid dynamics, thermodynamics, structural mechanics, and more. Your expertise becomes the benchmark that the next generation of AI learns from.

This is a fully remote, flexible contract role - work on your own schedule, on your own terms.

What You'll Do

• Design Advanced Engineering Problems
  - Craft challenging, domain-specific problems across FEA, heat transfer, kinematics, material science, and mechatronics to stress-test AI performance
• Author Ground-Truth Solutions
  - Develop rigorous, step-by-step technical solutions that serve as authoritative benchmarks for AI training
• Audit AI-Generated Reasoning
  - Evaluate AI outputs including CAD logic, thermodynamic proofs, and material specifications for technical accuracy, safety, and compliance with engineering standards (ASME, ISO, etc.)
• Refine Model Thinking
  - Identify flaws in AI reasoning - such as incorrect force distributions, energy conservation violations, or unit errors - and provide structured feedback to improve model performance

Who You Are

• Pursuing or holding a Master's or PhD in Mechanical Engineering, Aerospace Engineering, or a closely related field
• Strong foundational expertise in one or more core areas: solid mechanics, fluid mechanics, thermodynamics, CAD/CAM, or manufacturing processes
• Able to communicate complex physical phenomena and technical concepts clearly and precisely in writing
• Meticulous attention to detail - especially when reviewing mathematical derivations, unit conversions, and physical system constraints
• No prior AI experience required - we'll provide everything you need to get started

Nice to Have

• Experience with data annotation, technical evaluation, or quality assurance workflows
• Proficiency in engineering software such as SolidWorks, MATLAB, or ANSYS
• Familiarity with evaluating AI-generated code or simulation workflows

Why Join Us

• Work on genuinely cutting-edge AI projects alongside top research labs and engineering experts
• Fully remote and asynchronous - you set your own schedule
• Freelance flexibility with the substance of high-impact technical work
• Gain rare, first-hand exposure to how advanced large language models are trained and evaluated
• Potential for ongoing work and contract extension based on performance
