Mechanical Engineering AI Trainer About The Role We partner with the world's leading AI research labs to build smarter, more capable AI systems — and we need mechanical engineers to make it happen. As an AI Trainer, you'll use your deep technical expertise to challenge, evaluate, and improve how advanced language models reason through complex engineering problems. This is a unique chance to work at the frontier of AI development without leaving your home office.

Your knowledge of fluid dynamics, thermodynamics, structural mechanics, and more will directly shape the next generation of AI.

Organization: Alignerr

Type: Hourly Contract

Location: Remote

Commitment: 10–40 hours/week What You'll Do Design Challenging Problems — Create advanced mechanical engineering problems spanning FEA, heat transfer, kinematics, material science, and mechatronics to stress-test 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 logical errors such as incorrect force distributions or energy conservation violations, and provide structured feedback to improve model performance





Document Failure Modes — Systematically record where and how AI reasoning breaks down so research teams can harden model capabilities Who You Are Holds or is pursuing a Master's or PhD in Mechanical Engineering, Aerospace Engineering, or a closely related field
