AlignerrCoding & software eval
Mechanical Engineering Expert - AI Content Specialist
up to $60/hr
About this role, in Alignerr's words
We're looking for mechanical engineering specialists to help train and evaluate cutting-edge AI models. Your deep technical knowledge will directly shape how AI understands and reasons through complex engineering problems — from fluid dynamics and thermodynamics to structural mechanics and FEA.
What you'll do
- Design Complex Engineering Problems — Craft advanced, multi-domain mechanical engineering challenges across areas like finite element analysis (FEA), heat transfer, kinematics, fluid mechanics, and material science to rigorously test AI performance
- Author Ground-Truth Solutions — Develop precise, step-by-step technical solutions and benchmark responses that serve as the gold standard for AI learning
- Audit AI Technical Reasoning — Evaluate AI-generated outputs including CAD logic, thermodynamic proofs, and material specifications for accuracy, safety, and compliance with engineering standards (e.g., ASME, ISO)
- Refine AI Reasoning Processes — Identify logical errors such as incorrect force distributions, energy conservation violations, or flawed material assumptions, and provide structured feedback to improve how AI models "think"
Candidate background
Who You Are
- Holds a Master's degree (in progress or completed) or PhD in Mechanical Engineering, Aerospace Engineering, or a closely related field
- Strong foundational expertise in one or more core domains: solid mechanics, fluid mechanics, thermodynamics, CAD/CAM, mechatronics, or manufacturing processes
- Able to communicate complex technical concepts and physical phenomena clearly and precisely in written form
- Highly detail-oriented with a sharp eye for mathematical derivations, unit conversions, and physical system constraints
- No prior AI experience required — we'll get you up to speed
