Senior Satellite Systems Modeling Engineer — Government Mission

KGS LLC; El Segundo (CA); On-site; USD 150,000 - 190,000; Full time

Job summary

Amazon Leo is seeking a Modeling and Simulation Systems Engineer for government missions. You will assess Leo capabilities against government use cases and produce analyses supporting contract work.

Responsibilities include system modeling, mission engineering, and orbital mechanics, with emphasis on RF/optical link budgets and resource scheduling. Clear communication for reviews and proposals is essential.

Qualifications

• Bachelor's degree in mechanical, aerospace, manufacturing engineering or equivalent field.
• 8+ years in satellite or network system design, modeling and analysis.
• Strong understanding of orbital mechanics and constellation geometry.
• 8+ years coding experience in MATLAB, C, C++, or Python with standard practices.
• Working knowledge of RF or optical link budgets and impact on capacity/availability.
• Experience with resource scheduling, allocation, or optimization for a comms/satellite system.
• Strong written and verbal communication for customer briefings and reviews.

Responsibilities

• Own system-level modeling, simulation, and analysis for government mission scenarios and constellation designs across coverage, capacity, latency, and availability.
• Perform mission engineering by translating objectives into scenarios and measures of effectiveness.
• Apply orbital mechanics, including orbit geometry, reference frames, revisit and access behavior, and station-keeping considerations.
• Design and evaluate resource scheduling and allocation approaches for contact scheduling and beam assignment under power/thermal/spectrum limits.
• Evaluate multi-disciplinary trades in RF bandwidth and network resource allocation to optimize customer experience vs. cost and spectrum.
• Build and/or use RF and optical link budgets, combining with orbital dynamics to model capacity over time.
• Model inter-satellite geometry and access, including link windows and handover behavior.
• Extend existing simulation code (MATLAB/C++/Python) and create new models for a dynamic network topology.
• Prepare technical content for government customers and program reviews, including analyses and visuals.
