Senior Mechatronics Engineer

Summary

Headquartered in sunny Los Angeles, Gray Matter Robotics is a well-capitalized AI robotics startup serving the manufacturing industry. We empower shop floor workers with our smart robots that assist with tedious and ergonomically challenging tasks, specifically in automated surface finishing. Our proprietary GMR-AI™ software is integrated with state‑of‑the‑art industrial robots, sensors, and tools to create application‑specific turnkey solutions for customers through a Robot‑as‑a‑Service (RaaS) model.

We help manufacturers improve the quality of life for their workforce while increasing production capacity, and reducing scrap, repair, and rework costs. As a Senior Mechatronics Engineer, you will join our Design & Mechatronics team onsite in our Carson, CA office to explore, develop and test novel systems in house for implementation in the field.
