Job description

At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. But that’s just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known.

Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you're not just executing tasks; you're solving problems that haven’t been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you’re in propulsion, manufacturing, software, avionics, or a corporate function, you’ll collaborate across teams, shape decisions, and see your work come to life in record time. Relativity is a place where creativity and technical rigor go hand in hand, and your voice will help define the stories we’re writing together. Now is a unique moment in time where it’s early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum. The most meaningful work of your career is waiting. Join us.

About the Team:

Relativity Space pioneered large-scale additive manufacturing with our Terran 1 rocket, the largest 3D-printed object to fly. Now a distinct business unit within Relativity, Horizon Manufacturing Technologies is advancing next-generation manufacturing for aerospace and beyond. The team operates at the frontier of manufacturing innovation, where creativity meets capability. This is an environment where cutting-edge R&D is put into production, industrializing advanced manufacturing capabilities to solve customer problems. You’ll work alongside welders, robotics engineers, data scientists, and systems engineers at the intersection of hardware and software, creating an end-to-end additive manufacturing platform that serves a wide variety of applications. From exploring new materials to unlocking faster print speeds, to designing complex, organic geometries that can’t be built any other way, it’s high-impact work that sets the foundation for the future of advanced manufacturing.

As a Senior Electrical Engineer, you will contribute to the development, integration, and optimization of industrial automation systems for our cooperative multi-robot platform. You will help shape the electrical backbone of a tightly coordinated robotic system in which multiple robotic arms, mobile platforms, and manufacturing subsystems work together as a unified cell to enable flexible, high-throughput production. This role will focus on creating custom electrical hardware, unifying power and data architecture, improving reliability of electrical performance, and simplifying system integration and use. This is a chance to help define the electrical systems behind a highly collaborative robotic platform that pushes the boundaries of autonomy, coordination, and advanced manufacturing.

About the Role:

Work with a dedicated team of inventive engineers building a cohesive, next-generation robotics platform representing the future of autonomous manufacturing
Electrical Architecture and Hardware Development: Design and implement robust electrical architectures for robotic arms, AMRs, and supporting manufacturing equipment, while developing custom electrical hardware enable reliable and scalable across complex robotic platforms.
Power Distribution and Routing: Lead the design and routing of power across low-voltage and high-current systems, ensuring safe, reliable delivery to motors, sensors, tools, battery systems, and onboard compute systems
AMR Electrical Development: Support the early-stage design and buildout of a custom autonomous mobile robot, helping define and implement the electrical systems required for operation in industrial environments
Battery Systems Integration: Support the design, integration, protection, charging, and monitoring of battery-powered subsystems, particularly for mobile robotic platforms operating in industrial environments
Mechatronic Development: Contribute to the development of mechatronic structures and subsystem packaging, including electrical mounting, routing, thermal considerations, and integration with mechanical hardware
Integration and Testing: Collaborate with cross-functional teams including software engineers and system integrators to ensure seamless integration of electrical systems with centralized codebase and manufacturing infrastructure. Conduct thorough testing and validation to guarantee system functionality and reliability
Safety: Cultivate safety-critical engineering practices and ensure compliance with industry standards and regulations

About You:

BS, MS, or PhD in Electrical Engineering, Robotics, Mechatronics, or related field, with 4+ years of experience in related fields such as industrial automation, robotic systems, AMR development, electrical system integration, and/or advanced manufacturing equipment
3+ years of experience designing and implementing electrical systems for robotics, industrial equipment, or other complex electromechanical platforms
Experience developing custom electrical hardware and integrating components such as power distribution, sensors, safety systems, and industrial controls
Strong knowledge of power system design, including routing and protection for high-current devices, battery-powered systems, and mixed-power environments
Capability to troubleshoot and resolve complex electrical issues in industrial systems, ensuring reliability and performance
Good communication skills for work with cross-functional teams and ownership of knowledge bases
Willing to learn and utilize AI agent within workflows

Nice to haves but not required:

Familiarity with industrial protocols and data transmission such as EtherCAT, CANbus, and Ethernet/IP
Past work with motors, drivers and/or autonomous mobile robots (AMRs)
Familiarity with PLCs and industrial controls platforms such as Beckhoff/TwinCAT
Knowledge of motion control concepts and experience setting up motor drives
Experience working with industrial machinery and manufacturing processes including but not limited to welding, grinding, and milling
Experience contributing electrical-mechanical integration, packaging, and subsystem structural development
