At Relativity Space, we have two audacious goals: to build the next great commercial launch company with Terran R and to become America's leading force in additive manufacturing innovation. Both contribute to our long-term vision of creating humanity’s industrial base on Mars, paving the way for interplanetary life to expand the possibilities of the human experience. This journey begins right here on Earth – where we design, build, and fly rockets to deliver customer payloads to orbit. Terran R, our medium-to-heavy lift reusable rocket, fulfills the growing demand for launch capacity, thanks to our iterative approach that accelerates design, testing, and development while minimizing costs. While our groundbreaking research and development in 3D printing pushes the boundaries of large-scale additive manufacturing.
Your journey with us is more than just a job – it’s an opportunity to shape the future of aerospace technology, additive manufacturing, and the human experience alongside a community of passionate, creative individuals. Join us on this extraordinary journey, as we work together to transform our vision into reality.
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:
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.).

What the Team is Saying
What We Do
Welcome to Relativity Space, where we're rewriting the rules of rocketry. We have built and launched the world’s first 3D printed rocket, Terran 1, and are now bringing to market Terran R, our reusable medium-to-heavy-lift launch vehicle. Our iterative development approach revolutionizes the process from design to flight, ensuring we can scale to meet customer needs.
Our focus is clear: provide exceptional launch services that are highly competitive in the market. We design and manufacture cost-effective, high-performance, and reusable rockets at an unprecedented pace and scale – setting a new industry standard.
At Relativity Space, we have two audacious goals: build the next great commercial launch company with Terran R, and become America’s leading force in additive manufacturing innovation. Both ladder up to our long-term vision of creating humanity’s industrial base on Mars, paving the way for interplanetary life to expand the possibilities of the human experience. That journey begins right here on Earth—designing, building, and flying rockets to deliver customer payloads to orbit.
A medium-to-heavy lift reusable rocket, Terran R is designed to meet the ever-growing need for launch capacity. Our iterative approach accelerates the design, test, and development processes, enabling high-volume performance and reliability, with lower costs and shorter time to market. Our 3D printing research and development is at the bleeding edge, setting the standard for a new era of large-scale additive manufacturing.
Why Work With Us
We believe in a future where interplanetary life fundamentally expands the possibilities for the human experience. In realizing this, our long-term goal is to create humanity’s industrial base on Mars. The first step toward this long-term vision starts here on Earth – building rockets and pushing the boundaries of additive manufacturing.
