Mechanical Engineering

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 make it happen. As an AI Trainer, you'll stress-test advanced language models on complex engineering problems, expose their reasoning failures, and help define what engineering-grade AI looks like.

This is a rare opportunity to step outside traditional engineering work and directly influence how the next generation of AI understands fluid dynamics, thermodynamics, structural mechanics, and more.

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

What You'll Do

• Design Challenging Problems —
  • Craft advanced engineering problems across domains like FEA, heat transfer, kinematics, and material science to probe the limits of AI reasoning
  • Author Ground-Truth Solutions —
  • Write rigorous, step-by-step technical solutions that serve as benchmarks for AI learning
  • Audit AI Outputs —
  • Evaluate AI-generated CAD logic, thermodynamic proofs, and material specifications for accuracy, safety, and compliance with standards like ASME and ISO
  • Refine AI Reasoning —
  • Identify flawed reasoning — incorrect force distributions, energy conservation violations, unit errors — and provide structured feedback to improve model performance
  • Work Independently —
  • Complete task-based assignments on your own schedule, asynchronously

Who You Are

• Pursuing or completed a Master's or PhD in Mechanical Engineering, Aerospace Engineering, or a closely related field
• Strong foundational knowledge in solid mechanics, fluid mechanics, thermodynamics, CAD/CAM, or manufacturing processes
• Able to communicate complex technical concepts clearly and precisely in writing
• High attention to detail — especially with mathematical derivations, unit conversions, and physical system constraints
