Sr Software Engineer, Industrial Control

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 is on a mission to better connect humanity to space and the universe beyond our decades of experience scaling world-class technology organizations like Google CEO Eric Schmidt is guiding Relativity into itsnext phase: advancing Terran R toward launch and building the foundation for long-term impact.

The Terrestrial Software team is building the foundation for an automated rocket factory and integrated launch platform. Their mission is to automate and streamline workflows across the entire lifecycle of Terran R from raw material intake to launch operations and eventually manufacturing on Mars. Today that means partnering directly with teams across design materials manufacturing and test and launch to design implement and deploy end user enterprise-wide applications industrial automation data analytics infrastructure and next-generation AI to solve real problems and accelerate progress. Long term the team is laying the groundwork for a modular scalable software platform that can power highly autonomous operations on Earth and beyond. This is a team for builders and thinkers who thrive on cross-functional impact and want to shape the digital backbone of our future in space.

About the Role:

Designs and maintains the controller processes that run on safety-critical hardware focusing on fast deterministic binaries memory-based IPC and integration with field and TCP-based protocols.

About You:

• You have 6 years of experience building C or Rust software that runs on or near safety-critical hardware with a strong focus on correctness and reliability
• You have deep understanding of memory management and inter-process communication (IPC) and you are comfortable designing and debugging high-performance binaries that pass data efficiently between processes
• You have hands-on experience with real-time or near-real-time execution and you care about low jitter latency and throughput using common tools to track down performance and memory bottlenecks
• You are comfortable integrating with industrial communication protocols (e.g. CAN LXI Modbus RMC/DMCP OpenDAQ or similar) including moving data reliably over TCP between controllers and higher-level systems

Nice to haves but not required:

• Experience designing and operating systems running on a real-time OS or environments with tight real-time constraints
• Experience with lock-free or low-contention concurrency patterns for high-throughput data exchange between processes
• Familiarity with time-sensitive networking deterministic scheduling or other techniques used to coordinate multiple controllers in a safety-critical environment
• Prior experience bringing up or debugging hardware-in-the-loop test setups for controllers including working directly in lab environments with instruments and test equipment
