Space Systems Constellation Modeling Engineer

Amazon; Los Angeles (CA); On-site; USD 129,000 - 175,000; Full time

Job summary

Amazon space systems team in California seeks a Space Systems Modeling and Analysis Engineer to develop high-fidelity models of multi-orbit constellations for SATCOM, NAVWAR, SBST, and MWT missions. You will build large, fast simulations of LEO/MEO/GEO constellations and model ground segments and threats.

The role requires MATLAB/Python/C++ proficiency, experience with HPC, and U.S. citizenship to obtain a security clearance. Collaboration with government stakeholders is key.

Qualifications

• Bachelor's degree in a STEM discipline required.
• 3+ years of experience developing physics-based models and simulations of space systems.
• 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.
• U.S. citizenship and ability to obtain/maintain a security clearance.

Responsibilities

• Develop, validate, and maintain high-fidelity models of multi-orbit constellations (pLEO, MEO, GEO) 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 command and control infrastructure.
• Model space-based threats including maneuverable satellites, counter-space systems, and electromagnetic warfare effects on space architectures.
• Model Alt-PNT frameworks including timing budget analysis and navigation warfare scenarios.
• Analyze Space Data Network (SDN) architectures including space-to-space crosslinks, exchange points, and network service orchestration.
• Develop sensor performance models for multi-phenomenology detection (infrared, radar) across missile warning and moving target indication missions.
• Support architecture decisions by quantifying system resilience, capacity, and performance under adversarial conditions.
• Produce 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.
