About Prolific

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.

The role

We are seeking Mechanical Engineers to join our expert B2B and AI research network. This project supports the development of next-generation AI models by capturing how experienced engineers approach real-world CAD design challenges and validation workflows.

Joining our talent platform for this project also opens the door to similar paid projects in future. Everything is fully remote and ad hoc, on a freelance basis, with full control over which projects you accept.

Researchers for this project typically pay up to $120/hour for the main study. Participants must first complete a paid vetting survey and a screening call before being invited to the study.

What you'll bring

• Bachelor's degree or higher in Mechanical Engineering or a closely related field
• Strong proficiency with open-source CAD software (e.g., FreeCAD, KiCad, or similar)
• Python development experience with the ability to write and execute scripts independently (Desirable but not mandatory)
• Experience writing validation scripts (not just using pre-built tools) (Desirable but not mandatory)
• Comfortable working from the command line (Desirable but not mandatory)
• Strong analytical and problem-solving skills with excellent attention to detail
• A reliable internet connection and access to a computer

What you'll be doing in the role

• Paid vetting survey (Prescreener): Approximately 10 minutes, compensated at $12/hour
• Design physical objects suitable for 3D printing using open-source CAD software
• Complete engineering design tasks while your workflow, including tool usage, clicks, and design decisions, is captured to help train AI models on engineering problem-solving
• Write and execute Python validation scripts to support your design workflow
