Mechanical Engineer, Part-Time AI Engineering Task Authoring - Remote (United States)

• $60–$120 per hour equivalent, paid per accepted task • 100% remote • Part-time • About 15 hours a week, you choose when Paid, remote, part-time work creating and checking the mechanical engineering tasks that AI systems are trained on, on your own schedule. AI training is the human work behind AI systems: experts write, solve and review examples so that models learn to handle real problems. Engineering AI needs this from experienced mechanical engineers, because only they can tell whether a model, a simulation or a design calculation is physically sound and where the AI's answer goes wrong. What you'll do • Create rigorous mechanical engineering tasks involving design, physical modeling and simulation • Build computational models by defining geometry, meshes, materials, loads, contacts and boundary conditions • Run simulations and judge whether the results and analysis meet the physical and design requirements • Write and validate engineering solutions, then explain clearly where the AI's work is technically wrong or incomplete Why this is worth your time • Build practical engineering-AI evaluation skills while earning $60–$120 an hour equivalent, paid per accepted task • Apply your mechanical engineering judgment to structural, thermal, mechanical and multiphysics problems and help improve the technical accuracy of AI systems • Build practical experience using Python and coding agents on simulation-based engineering tasks and clear technical feedback • Fully remote and flexible, no fixed shifts, no commute Who this is for • A Mechanical Engineering MS or PhD, a degree in another engineering discipline closely related to it, or strong fundamentals in applied mechanics and mechanical engineering • Experience developing engineering solutions through analytical, computational or simulation-based methods, plus working knowledge of Python for solving engineering problems • Practical skill with coding agents and fluent English • Prior AI training work is not required. You bring the mechanical engineering expertise; the work provides structured engineering tasks and clear requirements to check them against. Pay and details • $60–$120 per hour equivalent as an independent contractor, paid per task that meets the project specifications • Part-time, about 15 hours a week, you choose when; fully remote, United States How to apply 1.
