Job description
Mechanical Engineering Expert (AI Training)
About the Role
We're looking for mechanical engineering experts to help train and improve cutting-edge AI models being developed with the world's leading AI research labs. Your deep technical knowledge will directly shape how AI understands and reasons through complex engineering problems — from fluid dynamics to finite element analysis.
This is a fully remote, flexible contract role. You set your own schedule and work as much or as little as fits your life.
- Organization: Alignerr
- Type: Hourly Contract
- Location: Remote
- Commitment: 10–40 hours/week
What You'll Do
- Design Challenging Problems — Create advanced mechanical engineering problems across domains like FEA, heat transfer, thermodynamics, kinematics, and material science to rigorously test AI performance
- Author Gold-Standard Solutions — Write clear, step-by-step technical solutions that serve as benchmarks for AI learning and evaluation
- Audit AI Reasoning — Review AI-generated outputs including CAD logic, thermodynamic proofs, and material specifications for accuracy, safety, and adherence to engineering standards (ASME, ISO, etc.)
- Improve AI Thinking — Identify logical errors in AI reasoning — such as incorrect force distributions or energy conservation violations — and provide structured feedback to sharpen 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 one or more of: solid mechanics, fluid mechanics, thermodynamics, CAD/CAM, or manufacturing processes
- Able to communicate complex technical concepts and physical phenomena clearly in writing
- Highly precise — you catch errors in mathematical derivations, unit conversions, and physical system constraints
- No prior AI experience required
Nice to Have
- Experience with data annotation, quality evaluation, or technical review workflows
- Familiarity with engineering software such as SolidWorks, MATLAB, or ANSYS
- Background in academic or professional technical writing
Why Join Us
- Work on genuinely cutting-edge AI projects alongside top research labs
- Fully remote and asynchronous — work on your own schedule, from anywhere
- Freelance perks: autonomy, variety, and global collaboration
- Gain rare insight into how advanced large language models are built and trained
- Potential for ongoing work and contract extension
