Senior Software Engineer

At Relativity Space were building rockets to serve todays needs and tomorrows breakthroughs. OurTerran R vehicle will deliver customer payloads to orbit meeting the growing demand for launchcapacity. But thats just the start. Achieving commercial success with Terran R will unlock newopportunities to advance science exploration and innovation pioneering progress that reaches beyondthe known.

Joining Relativity means becoming part of something where autonomy ownership and impact exist at every level. Here youre not just executing tasks; youre solving problems that havent been solved before helping develop a rocket a factory and a business from the ground up. Whether youre in propulsion manufacturing software avionics or a corporate function youll 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 were writing together. Nowis a unique moment in time where its early enough to leave your mark on the product the process andthe culture but far enough along that Terran R is tangible and picking up momentum. The mostmeaningful 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. Youll 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 cant be built any other way its high-impact work that sets the foundation for the future of advanced manufacturing

The Robotics Team at Relativity Space is responsible for building and refining the hardware that powers our autonomous systems. From advanced perception and robotics for manufacturing and additive processes to specialized robots that support development and deployment our R&D Software engineers work in close collaboration with hardware and automation to develop cutting-edge technologies that push the boundaries of space exploration and industrial manufacturing. As a key member of the team youll bring your software expertise to revolutionize the way robotics cooperate and additively manufacture here on earth and off planet.

About the Role:

As a Senior Software Engineer youll be responsible for shaping the core software that interfaces with our multi-robot manufacturing system. You wont be maintaining legacy codeyoull be defining patterns building reusable libraries and building out and transforming prototypes into production-grade systems that control and coordinate real-world robotics hardware. Youll work across the stack focusing on system orchestration state machines data handling and integration with perception motion and thermal systems. Your work wont be abstractyoull write the software that controls a system of robots merging perception automation and additive manufacturing. Test writing and debugging are core to this rolenot just checkboxes but crafts. You know how to build fast feedback into your workflow and how to isolate validate and debug complex real-world behavior. This is not a front-end or dev tools role. Its about building clean modular systems in C and Python that serve as the foundation for all STARR software.

About You:

• You write production-quality C C and Python or Rust with a strong focus on modularity clarity and testability
• Youve worked on robotics embedded systems perception pipelines or similar real-world platforms
• You know how to design and implement robust state machines and system-level orchestration
• You see around cornersyour experience helps you anticipate integration risks and failure modes early
• You treat debugging and test building as first-class engineering problems
• You collaborate well across disciplines and communicate clearly with hardware ML and controls teams
• Youre comfortable defining structure in early-stage systems and working independently toward high standards

Nice to haves but not required:

• Familiarity with ROS2 or deep experience working with ROS nodes and message-passing systems
• Experience integrating real-time sensor data from vision LiDAR or thermal systems
• Background in perception pipelines multi-robot coordination or HIL environments
• Proficiency with build systems like CMake and infrastructure tools like Docker
• Experience with data pipelines: saving structured logs database integration or time-series metrics
• Exposure to ML/AI environments especially wrapping or porting prototype code into production systems
• Background in additive manufacturing robotics platforms or industrial automation
