The job description
About the Role
We're looking for mechanical engineering experts to help train and evaluate cutting-edge AI models. Your deep technical knowledge will directly shape how AI understands and reasons through complex engineering problems — from fluid dynamics and thermodynamics to structural mechanics and beyond.
This is a rare opportunity to apply your advanced engineering background in a new and impactful way, working at the frontier of AI development alongside world-leading research teams.
What You'll Do
- Design Complex Engineering Problems — Craft advanced, multi-domain problems spanning FEA, heat transfer, kinematics, fluid mechanics, and material science to rigorously test AI performance
- Author Ground-Truth Solutions — Develop precise, step-by-step technical solutions and benchmark responses that guide AI learning
- Audit AI Reasoning — Evaluate AI-generated outputs including CAD logic, thermodynamic proofs, and material specifications for technical accuracy and compliance with engineering standards (e.g., ASME, ISO)
- Refine Model Thinking — Identify reasoning failures such as incorrect force distributions or energy conservation violations, and provide structured feedback to improve AI logic
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 reasoning clearly in writing
- Highly precise when working with mathematical derivations, unit conversions, and physical system constraints
- No prior AI experience required — we'll get you up to speed
Nice to Have
- Experience with data annotation, quality evaluation, or technical review workflows
- Familiarity with engineering software such as SolidWorks, MATLAB, or ANSYS
- Exposure to mechatronics, robotics, or multi-physics simulation
Why Join Us
- Work on cutting-edge AI projects with top-tier research labs and institutions
- Fully remote and flexible — work on your own schedule, from anywhere
- Freelance perks: autonomy, variety, and meaningful intellectual challenge
- Contribute to AI systems that need to get engineering right
- Potential for ongoing work and contract extension
