LEO Satellite Modeling & Simulation Engineer

Amazon; Redmond (WA); On-site; USD 129,200 - 174,800; Full time

Job summary

Amazon is seeking a Modeling and Simulation Engineer to develop models of the LEO satellite constellation and user-terminal algorithms, validating performance globally. You will collaborate across teams to maintain constellation models and integrate with terminal software, simulating motion, trajectories, and sensor fusion for robust handover performance.

The role focuses on architecting, developing, integrating, and verifying core algorithms within a simulation framework, supporting both

Qualifications

• Master's degree in electrical engineering, physics, mathematics, or an equivalent field.
• 5+ years of experience in satellite system design, modeling, and analysis, or equivalently complex time-dynamic systems.
• 4+ years of experience developing code in MATLAB or Python, with familiarity in industry-standard coding and regression practices.
• Experience working in a small team and drive beyond expectations to deliver results.

Responsibilities

• Develop models of Amazon LEO's satellite constellation and user terminal algorithms to validate user terminal performance globally.
• Collaborate with partner teams to develop and maintain the constellation model.
• Integrate the LEO satellite constellation with various user terminal algorithms.
• Develop motion trajectory and orientation models for mobility vehicles/vessels, including aviation, automotive, and maritime platforms.
• Simulate nominal and off-nominal operating cases for mobile user terminals.
• Validate end-to-end integration of the Sensor Fusion algorithm with other user terminal software and the satellite constellation.
• Develop test vectors to stress user terminals across all application cases, including residential, aviation, maritime, and automotive.
• Model all application cases—maritime, automotive, and aviation—by developing a sensor fusion model that feeds near-real-time vessel trajectory data to evaluate cell handover, satellite handover, performance at cell boundaries, and handover triggers.
• Analyze and model hardware/software capabilities and constraints to optimize run-time algorithms in the user terminal.
