Modeling and Simulation Engineer , Leo Customer Terminal

At Amazon were inventing on behalf of customers and with Amazon Leo were redefining what global connectivity looks like. Our mission is to deliver fast affordable broadband to unserved and underserved communities around the world through a constellation of low Earth orbit (LEO) satellites. Every system we build helps connect people to education healthcare opportunity and each other.

As a Modeling and Simulation Engineer you will be responsible for developing high-fidelity models of Amazons LEO satellite constellation and customer terminal algorithms to validate terminal performance globally across residential aviation maritime and automotive applications. You will work in a collaborative environment with a multi-disciplinary team including constellation RF antenna silicon algorithm and software engineers. Your focus will be on architecting integrating and verifying core customer terminal algorithms within a simulation framework encompassing sensor fusion motion trajectory modeling and satellite handover evaluation. You will simulate both nominal and off-nominal operating scenarios for mobile user terminals developing test vectors that stress the system across all application cases and mobility conditions. This role requires bridging hardware and software constraints to optimize run-time algorithms ensuring reliable satellite connectivity from early prototype validation through mass production.

Key job responsibilities
As a Modeling and Simulation Engineer you develop models of Amazon LEOs satellite constellation and user terminal algorithms to validate user terminal performance globally. This includes:
Collaborating with partner teams to develop and maintain Amazon LEOs constellation model
Integrating the LEO satellite constellation with various user terminal algorithms
Developing motion trajectory and orientation models for mobility vehicles/vessels including aviation automotive and maritime platforms
Simulating nominal and off-nominal operating cases for mobile user terminals
Validating the end-to-end integration of the Sensor Fusion algorithm with other user terminal software and the satellite constellation
Developing test vectors to stress user terminals across all application cases including residential aviation maritime and automotive
Modeling all application casesmaritime automotive and aviationby 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
Analyzing and modeling hardware/software capabilities and constraints to optimize run-time algorithms in the user terminal
