**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. This is a rare opportunity to work at the intersection of advanced engineering and frontier AI, entirely on your own schedule. * 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
