Mechanical Engineering AI Trainer

About The Role

We're looking for mechanical engineering experts to help train and improve cutting-edge AI models. Your technical knowledge will directly shape how AI understands and reasons through complex engineering problems — from fluid dynamics and thermodynamics to structural mechanics and FEA.

This is a unique opportunity to apply your advanced engineering expertise in a new and impactful way, working alongside world-leading AI research teams from the comfort of your own home.

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

What You'll Do

Design Complex Engineering Problems — Create advanced, domain-specific challenges across areas like finite element analysis (FEA), heat transfer, kinematics, thermodynamics, and material science to rigorously test AI performance Author Ground-Truth Solutions — Develop precise, step-by-step technical solutions and benchmark responses that guide the AI's learning process 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) Refine Model Thinking — Identify logical errors in AI reasoning — such as incorrect force distributions or energy conservation violations — and deliver structured feedback that improves how the model approaches engineering problems

Who You Are

Pursuing or holding a Master's or PhD in Mechanical Engineering, Aerospace Engineering, or a closely related field Deep foundational knowledge in one or more core areas: solid mechanics, fluid mechanics, thermodynamics, CAD/CAM, or manufacturing processes Able to communicate complex technical concepts clearly and precisely in written form Meticulous attention to detail when reviewing mathematical derivations, unit conversions, and physical system constraints No prior AI experience required — if you know engineering, we'll handle the rest

Nice to Have

Prior experience with data annotation, data quality, or evaluation workflows Proficiency in engineering software such as SolidWorks, MATLAB, or ANSYS Experience reviewing or auditing technical documentation to engineering standards
