Senior Electrical Engineer

Senior Electrical Engineer

Long Beach, California

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
• Cooperative Robotic Systems: Develop electrical architectures that support coordinated operation across multiple robotic arms, AMRs, tooling, and sensing systems, enabling reliable communication, synchronization, and system-level performance
• 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
• 4+ years of experience in related fields such as industrial automation, robotic systems, AMR development, electrical system integration, and/or advanced manufacturing equipment
• 1+ 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, motor drives, 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
• Familiarity with protocols such as EtherCAT, CANbus, Ethernet/IP, PROFINET, and safety protocols (FSoE, ProfiSafe) used in industrial automation
• Capability to troubleshoot and resolve complex electrical issues in integrated robotic or industrial systems, ensuring reliability and performance
• Good communication skills for work with cross-functional teams and ownership of knowledge bases

Nice to haves but not required:

• Experience with industrial robot arms (KUKA, ABB, Autonox, UR, etc.)
• Past work building and operating 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 with battery systems, including power distribution, charging, protection, and health monitoring
• Experience working with industrial machinery and manufacturing processes including but not limited to welding, grinding, and milling
• Experience contributing to mechatronic design, including electrical-mechanical integration, packaging, and subsystem structural development
• Proficiency in Python, C, and/or C++ for embedded, controls, or diagnostic tooling
• Familiarity with Robot Operating System (ROS2)
