Job summary

Amazon is seeking a Space Systems Modeling and Analysis Engineer to develop high-fidelity models of multi-orbit constellations (LEO, MEO, GEO) for SATCOM, NAVWAR, SBST, and MWT missions in Los Angeles. You will build fast, parallelizable simulations of proliferated constellations and assess performance, resilience, and network architectures.

The role requires a strong background in orbital mechanics, multi-regional modeling, and HPC methods using MATLAB, Python, or C++.

Qualifications

• Bachelor's degree in a STEM discipline.
• 3+ years of experience developing physics-based models and simulations of space systems (orbital mechanics, constellation design, RF link analysis, or sensor coverage).
• Experience modeling systems across multiple orbital regimes (LEO, MEO, GEO).
• Proficiency in MATLAB, Python, or C++ for numerical modeling and data analysis.
• Demonstrated experience with parallelizable or high-performance computing approaches for large-scale simulations.
• U.S. citizenship and ability to obtain/maintain a security clearance.

Responsibilities

• Develop, validate, and maintain high-fidelity models of multi-orbit constellations for SATCOM, NAVWAR, SBST, and MWT mission areas.
• Design and execute large-scale, parallelizable simulations to evaluate constellation performance, coverage, and resilience under nominal and degraded conditions.
• Perform trade studies and sensitivity analyses on constellation design parameters, sensor geometries, and network topologies.
• Model ground segment architectures including radar systems, ground entry points, and ground-based C2 infrastructure.
• Model space-based threats including maneuverable satellites, counter-space systems, and EW effects on space architectures.
• Model Alt-PNT frameworks including timing budget analysis and navigation warfare scenarios.
• Analyze Space Data Network architectures including space-to-space crosslinks and network service orchestration.
• Develop sensor performance models for multi-phenomenology detection across missile warning and MTI missions.
• Provide technical documentation, trade study reports, and briefings for engineering and program leadership.
• Collaborate with systems engineers, mission architects, and government stakeholders to translate operational requirements into simulation parameters.
