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 leads research and development of Relativity’s Stargate 3D-printing platform and factory operating system to produce large-scale metal structures for the industrial base. The team works with robotics engineers, data scientists, systems engineers, and welders to advance Relativity’s innovative tech stack, which leverages autonomy, advanced simulation, machine learning, and robotics. Working at the intersection of hardware and software, the team is creating a unified platform that can perform additive manufacturing, in-situ monitoring, NDE, and subtraction capabilities in a single print cell. Progressing in parallel to Terran R development, Relativity’s breakthroughs in large-scale additive manufacturing have the potential to revolutionize the defense industrial base.
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 (3D Simulation), you will be responsible for developing the robotics simulation platform, focusing on accurately simulating all the processes in our additive manufacturing systems and analyzing and visualizing data gathered in the printing process. You will also interact closely with the rest of the robotics software team and weld technicians to plan and implement new features for the simulation platform.
About You:
You have experience writing graphics software on Linux and Windows platforms, building user interfaces, and understanding the fundamentals of robotic simulations and data visualizations. You are comfortable in creating new tools and algorithms that enhance the capabilities of the simulated robot cell and know how to analyze and visualize various data gathered in the printing process.
- BS or MS in Computer Science, Robotics, Electrical Engineering, or a related field
- 8+ years experience developing large-scale projects in C/C++
- Solid knowledge of computer graphics and visualization techniques
- Demonstrated ability to create 3D applications (scientific visualizations, games, etc.)
- Experience with building user interfaces
- Expertise in exporting meshes, articulation hierarchies, bones, weights from CAD or modeling software and using in-game or in custom applications
