•    Develop new tools, scripts and automated workflows using Python or MATLAB to enhance analysis efficiency.
•    Maintain understanding of U.S. Space Domain (SDA) capabilities and counter threats.
•    Develop productive relationships with Program Office, Prime and Subcontract, functional IC or DoD counterparts  and other SME
•    Execute link budgets for satellite communication systems, optimizing signal-to-noise ratio, interference, and power allocations.
•    Identify and mitigate interface risks, driving technical issue resolution across engineering teams.
•    Support system integration and test activities, providing authoritative documentation and clarification.
•    Manage Interface Control Working Groups (ICWGs) and ensure consistent stakeholder communication.
•    Develop acquisition and technical requirements-related briefings, plans, and documentation for government decision-making.
•    Champion continuous learning and adoption of cutting-edge tools, technologies, and practices.
