Job description

Are you a mechanical engineering expert eager to shape the future of AI? Large‑scale language models are evolving from clever chatbots into powerful engines of scientific discovery. With high‑quality training data, tomorrow’s AI can democratize world‑class education, keep pace with cutting‑edge research, and streamline technical work for engineers everywhere. That training data begins with you—we need your expertise to help power the next generation of AI.

We’re looking for mechanical engineering specialists who live and breathe thermodynamics, fluid mechanics, heat transfer, dynamics and vibrations, solid mechanics, control systems, finite element analysis, and mechanical design. You’ll challenge advanced language models on topics like stress‑strain analysis, HVAC systems, machine kinematics, materials selection, energy systems, manufacturing processes, and computational simulations—documenting every failure mode so we can harden model reasoning.

On a typical day, you will converse with the model on engineering scenarios and theoretical mechanical engineering questions, verify factual accuracy and logical soundness, capture reproducible error traces, and suggest improvements to our prompt engineering and evaluation metrics.

A PhD in mechanical engineering or a closely related engineering field is ideal; peer‑reviewed publications, CAD/CAE project experience, system design work, or applied research in mechanical systems signal fit. Clear, metacognitive communication—“showing your work”—is essential.

We offer a pay range of $8‑to‑$65 per hour, with the exact rate determined after evaluating your experience, expertise, and geographic location. Final offer amounts may vary from the pay range listed above. As a contractor you’ll supply a secure computer and high‑speed internet; company‑sponsored benefits such as health insurance and PTO do not apply.
