Senior Electrical Engineer

About the role

Relativity is seeking a Senior Electrical Engineer to develop industrial automation for our multi-robot manufacturing platform. You will design the electrical architecture for coordinated robotic systems, including mobile platforms and robotic arms, to advance our additive manufacturing capabilities. In this role, you will own the end-to-end electrical design cycle for critical manufacturing systems from initial concept through production validation. You will define system requirements, create high-level and detailed schematics, and translate complex mechanical and software requirements into robust electrical solutions. This position requires a systems-level thinker who can bridge the gap between theoretical design and real-world industrial deployment. You will ensure that our electrical systems meet stringent reliability, safety, and performance standards in a demanding manufacturing environment. The successful candidate will act as a technical leader, guiding junior engineers and collaborating closely with cross-functional partners to deliver scalable automation infrastructure.
