Mechanical Engineering AI Trainer

About The Role

We're looking for mechanical engineers to help train and evaluate cutting-edge AI models being developed by the world's leading AI research labs. Your deep technical expertise will directly shape how AI reasons through complex engineering problems — from fluid dynamics to structural mechanics.

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

What You'll Do

• Design Complex Engineering Problems — Create advanced, multi-step challenges across domains like FEA (Finite Element Analysis), heat transfer, kinematics, thermodynamics, and material science to rigorously stress-test AI performance
• Author Ground-Truth Solutions — Develop precise, step-by-step technical solutions and benchmark responses that guide AI learning and set the standard for engineering reasoning
• Audit Technical Outputs — Evaluate AI-generated results including CAD logic, thermodynamic derivations, and material specifications for accuracy, physical validity, and adherence to engineering standards (ASME, ISO, etc.)
• Refine AI Reasoning — Identify flaws in AI reasoning — such as incorrect force distributions, energy conservation violations, or improper boundary conditions — and deliver structured feedback that improves model performance

Who You Are

• Pursuing or holding a Master's or PhD in Mechanical Engineering, Aerospace Engineering, or a closely related discipline
• Strong foundational knowledge across core ME domains: solid mechanics, fluid mechanics, thermodynamics, CAD/CAM, or manufacturing processes
• Able to communicate complex physical concepts and mathematical reasoning clearly in written form
• Meticulous attention to detail — especially when reviewing derivations, unit analysis, and system constraints
• No prior AI or data annotation experience required

Nice to Have

• Prior experience with data annotation, evaluation systems, or technical writing
• Hands-on proficiency with engineering tools such as SolidWorks, ANSYS, or MATLAB
• Familiarity with engineering simulation workflows or AI-generated code review

Why Join Us

• Work on some of the most advanced AI models being built today
• Fully remote and async — work when and where it suits you
• Freelance autonomy with meaningful, intellectually stimulating work
• Collaborate with a global network of domain experts and AI researchers
• Ongoing contract potential as projects grow and expand
