Mechanical Engineering

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 make it happen. This is a unique opportunity to apply your deep domain expertise in a completely new way: stress-testing and refining advanced AI systems on problems in fluid dynamics, thermodynamics, structural mechanics, and more.

If you've ever wanted to see how cutting-edge AI thinks — and then make it think better — this role is for you.

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

What You'll Do

• Design Challenging Problems — Craft advanced mechanical engineering problems spanning FEA, heat transfer, kinematics, material science, and mechatronics that push AI models to their limits
• Author Gold-Standard Solutions — Develop rigorous, step-by-step technical solutions that serve as benchmarks for AI learning and evaluation
• Audit AI Reasoning — Evaluate AI-generated outputs including CAD logic, thermodynamic proofs, and material specifications for technical accuracy, safety, and compliance with engineering standards (ASME, ISO, etc.)
• Sharpen Model Thinking — Identify flaws in AI reasoning — such as incorrect force distributions, energy conservation violations, or faulty failure analysis — and provide structured feedback to improve model performance

Who You Are

• Holds a Master's (pursuing or completed) or PhD in Mechanical Engineering, Aerospace Engineering, or a closely related field
• Strong foundational knowledge in one or more core areas: solid mechanics, fluid mechanics, thermodynamics, CAD/CAM, or manufacturing processes
• Able to communicate complex physical phenomena and technical derivations clearly in writing
• High attention to detail when reviewing mathematical derivations, unit conversions, and 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 processes
• Familiarity with engineering software such as SolidWorks, MATLAB, ANSYS, or similar tools
• Background in academic research or technical writing

Why Join Us

• Work on genuinely cutting-edge AI projects alongside top research teams
• Fully remote and flexible — work on your own schedule, from anywhere
• Freelance autonomy with the substance of meaningful, intellectually stimulating work
• Gain rare, behind-the-scenes exposure to how advanced large language models are trained and improved
• Potential for ongoing work and contract extension as new projects launch
