- Collaborate with systems, software, hardware, and integration teams to derive modeling needs, assumptions, and use cases.
- Plan and execute model verification and validation activities, including defining validation criteria, identifying data sources, and comparing model outputs to test, flight, or operational data.
- Document model assumptions, limitations, key parameters, and V&V results; communicate model credibility and appropriate use to stakeholders.
- Use M&S results to support technical decisions, risk identification, and recommendations to program and customer leadership.
- Support preparation and delivery of technical briefings, results summaries, and trade study findings to internal and external stakeholders.
