From Amazon's posting. “We” and “our” refer to the employer.
At Amazon, we’re inventing on behalf of customers, and with Amazon Leo, we’re 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 Amazon's 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 LEO's satellite constellation and user terminal algorithms to validate user terminal performance globally. This includes:
Modeling 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
Analyzing and modeling hardware/software capabilities and constraints to optimize run-time algorithms in the user terminal
Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.
The LEO Customer Terminal team is responsible for developing both outdoor and indoor devices that enable customers to access internet service via the LEO satellite network. We own the entire process from early prototypes through mass production, including requirements documentation, architecture definition, hardware development, algorithm development, and all integration and verification testing.
The base salary range for this position is listed below. Your Amazon package will include sign-on payments and restricted stock units (RSUs). Final compensation will be determined based on factors including experience, qualifications, and location.
Amazon also offers comprehensive benefits including health insurance (medical, dental, vision, prescription, Basic Life & AD&D insurance and option for Supplemental life plans, EAP, Mental Health Support, Medical Advice Line, Flexible Spending Accounts, Adoption and Surrogacy Reimbursement coverage), 401(k) matching, paid time off, and parental leave.
