Engineering Design and Simulation (CAD & Simulation Consultant) - Aerospace / Mechanical / Electrical Engineering Prolific is not just another player in the AI space – we are building the biggest pool of quality human data in the world.
Over 35,000 AI developers, researchers, and organizations use Prolific to gather data from paid study participants with a wide variety of experiences, knowledge, and skills.
About the Project: We are building a benchmark of physical engineering design tasks across mechanical, electrical and aerospace engineering. An AI agent then uses open-source engineering tools in a sandbox to deliver a design, and an automated grader checks whether it works. You will help create the tasks and graders that measure how well frontier AI models can do real engineering design work.
Role Overview: We are seeking experienced mechanical, electrical and aerospace engineers to design, build and review simulation‑led engineering tasks. You will turn real engineering problems into precise, measurable briefs, and write the graders and reference solutions that check them. The role needs strong engineering fundamentals, hands‑on simulation experience, and the ability to produce clear, reproducible work.
