• Engage in deep-technical work that shapes program development and operational excellence.
• 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.

Key Responsibilities:

•Lead rapid optical and trajectory analysis for satellite systems, supporting mission planning and performance assessments.

• Use Systems Tool Kit (STK) to apply provided access constraints and perform simple sensor modeling to support technical analysis and assessment of mission requirements.
• Develop and maintain Satellite Interface Control Documents (ICDs) for spacecraft, ground systems, payloads, and cross-system interfaces.
• Serve, and maintaining alignment with project objectives and schedules
• 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.
