À propos de ce poste Senior GNC Simulation Engineer chez Relativity Space
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 Guidance, Navigation, and Control (GNC) and Performance teams are responsible for defining and analyzing how Terran R flies, from liftoff to landing. The work combines a variety of disciplines such as advanced modeling, orbital mechanics, software development, and dynamic systems to optimize every phase of flight. You’ll develop flight algorithms, simulate trajectories, and model Terran R’s dynamic behavior across mission profiles. Whether you're early in your career or a seasoned expert, you’ll have the opportunity to own critical pieces of the system, influence design, and see your work fly. The department is part of the Integrated Performance team, uniting key disciplines to drive performance at every stage of the mission.
About the Role:
- You will be a key contributor to the 6DOF simulation used for GNC algorithm development, Monte Carlo analysis, and hardware-in-the-loop (HITL) testing
- Work with analysis and hardware teams to develop and integrate subsystem models into the 6DOF simulation
- Implement numerical solvers and physics models
- Develop simulation configuration, scheduling, logging, and Monte Carlo capabilities
- Develop simulation interfaces with GNC algorithms
- Maintain and improve the development environment for simulation users
- Contribute to other cross-functional software packages at Relativity
About You:
- An undergraduate or graduate degree (BS/MS/PhD) in engineering, physics, mathematics or related disciplines
- 5+ years of relevant full-time work experience
- Proficiency with compiled (e.g. C++, Rust) and scripted (e.g. Python) languages
- Experience developing physics-based simulations of aerospace vehicles
- Ability to work in a fast paced and intense startup environment
- Ability to complete projects with ownership of end-to-end solutions with a high degree of independence
Nice to haves but not required:
- Familiarity with the design and analysis of launch vehicles or space systems
- Experience developing aerospace vehicle simulations that interface with GNC algorithms and/or hardware-in-the-loop (HITL) testing
- Experience implementing high-performance computing (HPC) solutions
- Experience implementing software development practices and workflows such as Docker, continuous integration (CI), and continuous deployment (CD)
