About the job
Develop and extend constellation simulation software that models orbital dynamics, satellite link performance, and system behavior, while supporting system resource management and engineering decisions.
What you'll do
- Maintain and extend the Python/Rust simulation tool, including orbital mechanics and RF link models; validate results against applicable tools such as STK/HPOP.
- Build performance-critical simulation components and interfaces, and support constellation trade studies, requirements analysis, and system architecture decisions.
- Help develop the System Resource Manager for satellite power allocation, frequency assignment, cell-to-satellite assignment, and capacity planning.
What they ask for
- 2-5 years of professional software engineering experience, with strong proficiency in Python and Rust.
- Demonstrated experience building or maintaining simulation, modeling, or numerical computing tools.
- Working knowledge of orbital mechanics, including Keplerian elements, J2 effects, constellation geometry, and propagation methods.
- Familiarity with satellite systems fundamentals, including link budgets, antenna gain/beamforming, SINR/EIRP, and RF link performance.
Nice to have
- Experience with STK or other orbital simulation/propagation tools.
- Knowledge of satellite communications systems or experience with graph-based or ML-driven optimization for satellite resource management.
Tools
Python, Rust, STK/HPOP, PyO3, CI/CD
