We are looking for a System Modeling Engineer to design, build, and maintain models of complex space/aerospace systems. You will work closely with systems engineering, mission design, software, and operations teams to create models that support design trade studies, performance analysis, simulations, and operational decision-making.

You’ll be responsible for translating real-world subsystem behavior (e.g. power, thermal, ADCS, communications, propulsion, payload) into digital models that are accurate, maintainable, and well-integrated with our existing tool-chain and data sources.

Key Responsibilities:

​
- System & Subsystem Modeling
- Develop end-to-end models of spacecraft / aerospace system behavior (power budgets, data budgets, thermal, ADCS, COMMS, mission timelines, etc.).
- Build and maintain parametric models for key subsystems to support trade-offs and architecture decisions.
- Integrate telemetry / flight data to calibrate and validate models.
- Simulation & Analysis
- Set up and run simulations to evaluate performance under different scenarios (nominal, degraded,



and failure modes).
- Support mission analysis (coverage, visibility, link margins, duty cycles, consumables usage).
- Perform sensitivity, Monte Carlo, and worst-case analyses to understand margins and risks.
- Tooling & Automation
- Develop reusable modelling components, scripts, and tools in environments such as Python, MATLAB/Simulink, Modelica, or similar.
- Connect models with databases and tools (e.g. telemetry DBs, digital twin / monitoring systems, configuration management).
- Help define interfaces so models can be used by other teams (APIs, config files, parameter sets).
- Requirements & Verification Support
- Translate system-level requirements into model assumptions, parameters, and test cases.
- Use modelling results to demonstrate requirement compliance and support verification activities.
- Contribute to design reviews (SRR, PDR, CDR, ORR, etc.) with explicit visualizations and mo
