What you'll doHelp design, assemble and test a scoped fixture or electromechanical subsystem.
Measure fit and repeatability, compare results with the design and update documentation.
Work with software and controls engineers on the subsystem's interfaces.
Working toward a relevant degree or equivalent practical training.
CAD and hands-on build experience from a course, team or personal project.
Can explain design decisions and failures. Formula-team experience is welcome, not required.
Apply with your resume and a short description of something you built. Project links are optional. Tell us what you owned, what failed and how you tested the fix. Coursework, student teams and personal projects count.

What We Do
Relling builds and deploys turnkey, AI-native robot workcells for American manufacturers, targeting high-mix, contact-rich production tasks that conventional automation struggles to handle. Its systems automate assembly, machine tending, finishing, kitting, welding, and inspection—work that classical automation cannot economically handle. Cells are scoped and qualified off-site, then run on US factory floors in weeks, bringing physical AI into practical manufacturing operations.
