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. Each task describes what a device must do. 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.

Key Responsibilities: Strong proficiency in CAD engineering and simulation tools

candidates must have a minimum of 5+ years of experience working in CAD engineering and simulation-focused organizations
Strong aerospace/mechanical/electrical engineering fundamentals
Hands‑on experience with modeling, simulation, or design projects
Analytical mindset with strong problem‑solving skills
Ability to work independently in a fast‑paced environment
Robust engineering problem definition
Modelling and simulation
Analytical validation and sanity checking




Design trade‑off analysis
Technical documentation
Peer review and quality assessment
Clear communication of assumptions and engineering decisions
Proficiency in the following tools as per their domain:
CAD: FreeCAD, Cad Query, build123d (STEP output)
Structural: Gmsh + CalculiX; Code_Aster
Motion: MuJoCo or another scripted multibody simulator that supports closed loops
Electrical: ngspice, KiCad; open PDK flows (e.g. SKY130 with Magic / KLayout) for IC layout
Aero / fluids: XFOIL, AVL, OpenVSP / VSPAERO, XFLR5, Mach UpX; OpenFOAM where the budget allows
