Mechanical Design Intern - Immediate Fill

Summary

GrayMatter Robotics is a well-capitalized Physical AI company headquartered in Los Angeles, building Factory SuperIntelligence (FSI) through systems that learn, adapt, and develop genuine process intelligence across every part they touch. Our robots take on the tedious, hazardous, and ergonomically demanding work that has kept manufacturing dependent on a shrinking skilled workforce, delivering superhuman performance. Robotics has a demo problem. GMR doesn't. Our systems are in active production today, adapting autonomously to real geometries, real materials, and real process variation without reprogramming. We deliver our system through a Robots-as-a-Service (RaaS) model that converts capital expenditure into an operating subscription, making Physical AI accessible to the manufacturers who need it most. We hire people who want to solve hard physical problems at an industrial scale.

We help manufacturers improve shop floor workers’ quality of life, increase production capacity, and reduce scrap, repair, and rework costs. As a Mechanical Design Intern you will join our Mechatronics & Design Team to collaborate with our engineering team onsite in our Gardena, CA office to support the design process from concept to implementation while learning and contributing to the engineering team's objectives in a collaborative environment.
