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 Why Join Us
• Work on genuinely cutting-edge AI projects with top research labs and AI teams
• Fully remote and versatile — set your own schedule and work at your own pace
• Gain firsthand exposure to how advanced large language models (LLMs) are built and trained
• Freelance autonomy with the support of a collaborative, global team
• Potential for ongoing work and contract extension based on performance
