Mechanical Engineering - AI Trainer
About the Role
We're looking for mechanical engineering experts to help train and improve the next generation of AI models. Working with Alignerr - a partner to the world's leading AI research labs - you'll stress-test advanced language models on complex engineering problems, expose their reasoning failures, and help build AI that truly understands the physical world.
This is a rare opportunity to apply your deep technical knowledge in a high-impact, flexible freelance role - no office, no commute, no rigid schedule.
* Organization
: Alignerr
* Type
: Hourly Contract
* Location
: Remote
* Commitment
: 10-40 hours/week
What You'll Do
* Design Challenging Problems
- Craft advanced engineering scenarios across fluid dynamics, thermodynamics, FEA, heat transfer, kinematics, and material science to probe the limits of AI reasoning
* Build Ground-Truth Solutions
- Author rigorous, step-by-step solutions that serve as the gold standard for AI learning and benchmarking
* Audit Technical Outputs
- Evaluate AI-generated CAD logic, thermodynamic proofs, and material specifications for accuracy, safety, and compliance with engineering standards (ASME, ISO, etc.)
* Sharpen AI Reasoning
- Identify flaws in AI reasoning - such as incorrect force distributions, energy conservation violations, or faulty assumptions - and provide structured feedback to improve model performance
Who You Are
* Pursuing or holding a Master's or PhD in Mechanical Engineering, Aerospace Engineering, or a closely related field
* Strong foundational knowledge in at least one of: solid mechanics, fluid mechanics, thermodynamics, CAD/CAM, or manufacturing processes
* Able to communicate complex technical concepts clearly and concisely in written form
* Highly precise when reviewing mathematical derivations, unit conversions, and physical system constraints
* Self-motivated and comfortable working independently on an asynchronous schedule
* No prior AI experience required - we'll get you up to speed
Nice to Have
* Experience with data annotation, technical writing, or evaluation workflows
* Proficiency with engineering software such as SolidWorks, MATLAB, or ANSYS
* Familiarity with AI or large language model outputs
Why Join Us
* Work on genuinely cutting-edge AI projects alongside top research labs
* Fully remote and flexible - work on your own schedule, from anywhere
* Freelance autonomy: choose your hours, manage your workload
* Gain rare insight into how frontier AI models are built and trained
* Potential for ongoing work and contract extension
