Robotics Engineer II

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.

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.

As member of the Horizon's Robotics Team, you'll work alongside welders, data scientists, and material scientists, 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.

A Systems Robotics Engineer at Horizon Manufacturing Technology contributes to the development, integration, and optimization of automation systems for our robotics manufacturing platform. The main focus is on designing and implementing robotic control systems, functional safety, and developing real-time systems to enhance operational efficiency and precision. Horizon's team is highly cross-functional, so a successful Systems Robotics Engineer owns projects while working with stakeholders in a dynamic R&D environment.

Responsibilities include:

• Coordinate and lead development projects for new devices, such as sensors, end effectors, and motion systems. Identify requirements, design solutions, develop and integrate with the existing robot cells to serve the needs of the manufacturing processes
• Commissioning EtherCAT networks and safety systems using TwinCAT and TwinSAFE
• Configuring Kuka robot systems, such as determining drive systems, connecting motors and peripheral devices, setting up Safe Op, and configuring I/O systems
• Calibration and verification of robot cell operation, using industrial metrology and tracking systems
• Design, fabrication, and debug of low voltage electrical enclosures
• Support robot cell operation for both production and R&D applications, including debugging code and adjusting cell configuration parameters

• Education:
  
  BS, MS, or PhD in Electrical Engineering, Mechanical Engineering, Computer Science, Robotics, or a related field, or self-taught with extensive hands-on experience
• 3+ years of experience in robotics control systems:
  In-depth knowledge of designing, implementing, and optimizing control systems for industrial robotic applications.
• Demonstrated ability to troubleshoot and resolve complex issues in automation systems, ensuring reliability and performance
• Good communication and collaboration skills:
  Ability to effectively communicate technical concepts and work in cross-functional teams to achieve project goals.
• Familiarity with protocols such as EtherCAT, CANbus, Ethernet/IP, PROFINET, and safety protocols (FSoE, profiSAFE) used in industrial automation
• Experience with functional safety standards in industrial automation such as ISO
  13849 and ISO
  61508, as well as performing standardized risk assessment such as described in ISO
  12100
• Experience with motion and kinematics, such as in the context of robot reachability studies, servo control, accuracy and calibration, and path planning
• Proficiency with Git or other revision control methods

Nice to haves but not required:

• Experience with programming Structured Text and configuring Programmable Logic Controllers (PLCs) for industrial automation
• Experience with CAD/CAM for…
