Description
? SAIC's National Security and Space Sector (NSS) seeks a Guidance Navigation & Control Engineer to drive mission-critical engineering and analytical solutions for joint Intelligence Community (IC) and Department of Defense (DoD) space programs.

Based in Aurora, Colorado, you'll join a collaborative team of U.S. Government civilians and contractors, working on the nation's most advanced space and counter-space initiatives. Why SAIC? Work on "crown jewel" programs with direct impact on national security and space operations. Collaborate with Subject Matter Experts (SMEs) in physics, math, RF, optics, space acquisition, operations, and intelligence analysis. 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.
