GNC Simulation Engineer II Verified today
About the Team
The Guidance, Navigation, and Control (GNC) and Performance teams define and analyze how Terran R flies, from liftoff to landing. The work combines 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.
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
What We're Looking For
- Undergraduate or graduate degree (BS/MS/PhD) in engineering, physics, mathematics or related disciplines
- 2+ years of relevant full-time work experience
- Proficiency with compiled languages (C++, Rust) and scripted languages (Python)
- Experience developing physics-based simulations of aerospace vehicles
- Ability to work in a fast-paced startup environment
- Ability to own end-to-end solutions with high degree of independence
Nice to Have
- Familiarity with launch vehicle or space systems design and analysis
- 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 with Docker, continuous integration (CI), and continuous deployment (CD)
Compensation
Hiring range: $126,000 to $188,000 USD. Relativity Space offers competitive salary and equity, generous PTO and sick leave, parental leave, annual learning and development stipend, and additional benefits.
