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:

The Additive Technology team operates at the frontier of research and development, where creativity meets capability. This is an R&D-driven environment where problems are open-ended and solutions are yours to define. 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 additive manufacturing.

About the Role:

This role is part of our Robotics Software Engineering team, building out a novel type of cooperative robotic platform that utilizes our large-scale additive manufacturing systems. This platform will pave the way for the continuous invention of new capabilities. We prioritize performance, simplicity, simulation/testing, and reusability, building cohesive interfaces with every piece of equipment we use. Our team provides a system with which custom robots and additive systems can be built and integrated seamlessly. As a Staff Robotics Software Engineer you will be responsible for the development of a flexible and safe robotics operating platform, focusing on the low-level execution environment, messaging and communications, integration with robots and equipment, and providing interfaces to further develop applications and integrations that leverage the core platform.

About You:

You have experience in writing Linux software at all levels, real-time operating systems, industrial robotics, planning and decision making for autonomous systems, simulation and visualizations, and are comfortable creating tools and algorithms to process positional, sensor and motion data to ensure the robotic print cell is able to achieve highly repeatable and accurate motion throughout a print profile while responding to dynamic input.

Education: BS or MS in Computer Science, Robotics, Electrical Engineering, or a related field

Experience incorporating various sensors (e.g., lidar, cameras, IMUs) into systems, optimizing for accuracy and reliability

8+ years experience developing large-scale projects in C/C++ and/or Rust for long lifecycle products

Demonstrated ability to configure build system to generate builds for multiple target hardware platforms and testing harnesses

Knowledge of kinematics, dynamics, and control algorithms for precise robot motion planning and execution

Experience with EtherCAT and other industrial protocols: Familiarity with industrial communication standards and their application in high-performance robotic systems

Nice to haves but not required:

Demonstrated ability in data visualization and GUI development for complex robotic systems

Experience working with ROS

Experience with TwinSAFE in non-TwinCAT environments

Knowledge of network administration
