- Job Description
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 Flight Software team is responsible for developing real-time and mission critical software to support the Terran R program including engine testing, stage testing, and static fire and launch operations. The team is responsible for the full life cycle of software, from working with GNC, Propulsion, Avionics teams to define functional and performance requirements, to developing the software, unit testing, developing CI/CDs, and then testing it against our various test platforms with physics sims. This team is responsible for the delivery of reliable and robust software that directly controls the Terran R rockets to reach orbit and perform Entry Descent and Landing.
About the Role:
Aerospace experience isn’t required. We value driven engineers with strong computer science fundamental who collaborate well to solve meaningful problems.
As a Staff Flight Software Engineer, you will be a technical leader within the team with a high level of autonomy tackling core flight software products that directly impact the Terran R program and be responsible for setting standards and best practices for the team along with mentoring junior engineers.
- Architect and deliver core flight software with a strong focus on meeting system and performance requirements such as latency, allowed jitter, and control frequency.
- Work closely with GNC engineers to integrate complex algorithms for vehicle ascent and re-entry, descent and landing.
- Work closely with Embedded Software Engineers and Avionics to integrate vehicle sensor data such as GPS, IMU, Radar, and to control vehicle equipment such as valves, thrust vector controls, and landing grid fins.
- Develop telemetry system that prioritizes, filters, stores and forwards, and encodes/decodes telemetry to RF format, and routes that data through ground stations and to data centers.
- Support the development and integration of testing infrastructure such as HITL (Hardware-In-The-Loop) and HOOTL (Hardware-Out-Of-The-Loop) and physics and fluid sims.
- Focus on maximizing the team's velocity by defining processes, best practices, integrating modern tools and technologies, and mentoring junior engineers.
About You:
- An undergraduate or graduate degree in a relevant engineering discipline (Electrical Engineering, Computer Engineering, Computer Science, Aerospace Engineering) and 7+ years of production development experience.
- Deep professional experience and technical expertise delivering production-level and real time embedded software.
- Expert in Rust, C++, and/or other system languages.
- Expert in algorithms and data structures.
- Expert in Operating System concepts such as memory management, CPU shielding, scheduling, etc.
- Experience with software development processes including: source control, bug tracking, and CI/CD.
Nice to haves but not required:
- Experience with developing fault and failure tolerant system and knowledge of voting and internal state synchronization.
- Experience with systems-level programming like synchronization primitives, memory management, etc.
- Experience with networking protocols (UDP vs TCP), OSI layers. switching and routing.
- Experience with developing software to a safety standard and achieving formal certification with a governing body (e.g. NASA, FAA, FDA, etc.).
