Flight Software Engineer II

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:

The Flight Software team is responsible for architecting developing and testing the real-time and mission-critical software that runs on the Terran R rocket. This includes software that autonomously controls all portions of the rocket from launch to reaching orbit and entry descent and landing. This team is at the forefront of driving Relativity Space towards our mission of a multiplanetary future.

About the Role:

Youll experience architecting developing and testing flight software interact with Avionics and Guidance Navigation and Control (GNC) teams and hands-on interface with hardware in the Avionics lab. At Relativity the software you develop will be a core piece of a software system that controls the entire vehicle operation and is mission critical. Youd be a strong fit if you have a strong passion for and foundation of what it means to develop highly reliable software following best practices around code quality and testing.
