Mechanical Engineering —

- AI Trainer

About The Role

We partner with the world's leading AI research labs to build smarter, more technically rigorous AI models — and we need mechanical engineers to help us do it. This is a unique opportunity to apply your deep domain knowledge in a completely new context: teaching AI how to reason through complex engineering problems.

If you have a strong foundation in fluid dynamics, thermodynamics, structural mechanics, or related disciplines, your expertise is exactly what's needed to push the boundaries of what AI can do in technical domains.

- Organization: Alignerr
- Type: Hourly Contract
- Location: Remote
- Commitment: 10–40 hours/week

What You'll Do

- Design Advanced Engineering Problems —
- Create challenging, domain-specific problems spanning FEA, heat transfer, kinematics, fluid dynamics, and material science to rigorously test AI performance.
- Author Ground-Truth Solutions —
- Develop precise, step-by-step technical solutions and benchmark responses that serve as the gold standard for AI learning.
- Audit AI Reasoning —
- Evaluate AI-generated outputs — including CAD logic, thermodynamic proofs, and material specifications — for technical accuracy, safety, and compliance with engineering standards (e.g., ASME, ISO).
- Identify and Correct Failures —
- Spot logical errors such as incorrect force distributions, energy conservation violations,



or flawed material assumptions, and provide structured feedback to improve how the AI reasons through problems.

Who You Are

- Advanced Degree —
- Currently pursuing or holding a Master's or PhD in Mechanical Engineering, Aerospace Engineering, or a closely related field.
- Deep Domain Knowledge —
- Strong foundations in solid mechanics, fluid mechanics, thermodynamics, CAD/CAM, or manufacturing processes.
- Clear Technical Communicator —
- Able to explain complex physical phenomena and mathematical derivations in clear, concise written form.
- Precision-Oriented —
- High attention to detail when reviewing mathematical derivations, unit conversions, and physical system constraints.
- No prior AI experience required — if you know your engineering, we'll handle the rest.

Nice to Have

- Prior experience in data annotation, quality evaluation, or technical review workflows
- Familiarity with engineering software such as SolidWorks, MATLAB, or ANSYS
