Original job description

Amazon Leo is a low Earth orbit satellite constellation providing low-latency, high-speed broadband connectivity to unserved and underserved communities around the world. The mission of Amazon Leo for Government is to leverage Leo and provide high speed, low latency, and secure satellite services to United States and allied government customers. As a Modeling and Simulation Systems Engineer supporting that mission, this role is primarily responsible for assessing and analyzing how both Leo's capabilities and Leo products built for government perform against government use cases, and for producing the analyses that underpin government contract work. You will evaluate system and network performance from the capacity, coverage, latency, and availability point of view to determine how Leo delivers the operational outcome the customer mission needs. It is a unique opportunity to innovate and define groundbreaking wireless technology with few legacy constraints.

Key job responsibilities

Own system-level modeling, simulation, and analysis for government mission scenarios and constellation designs, across coverage, capacity, latency, and availability, from concept trades through customer deliverables
Perform mission engineering: translate customer mission objectives into scenarios and measures of effectiveness, develop design reference missions and CONOPS, and model whether the end-to-end system delivers the required operational outcome
Apply orbital mechanics, including orbit and constellation geometry, reference frames, revisit and access behavior, and station-keeping and conjunction considerations, as the foundation of coverage, access, and contact analyses
Design and evaluate resource scheduling and allocation approaches, heuristic or solver-based, for contact scheduling, satellite beam assignment, and prioritization under power, thermal, and spectrum constraints
Evaluate complex multi-disciplinary trades involving RF bandwidth and network resource allocation to customers, optimizing customer experience against cost, power, and spectrum, including constellation design and link selection trades
Build and/or utilize RF and optical link budgets and combine them with orbital constellation dynamics to model time-varying system capacity, latency, and availability
Model inter-satellite geometry and access, including link availability windows, contact scheduling, and handover behavior
Extend existing simulation code and tools, and create new simulation models representative of the target system (primarily MATLAB, also C++ / Python), designing around hardware and software capabilities and constraints to support a dynamic network topology
Prepare and present technical content for government customers and program reviews, including analysis packages, visualizations, briefings, and proposal material
Account for self-interference and interference with other space and terrestrial communication systems in coverage and capacity analyses

Export Control : This position requires that the candidate selected be a U.S. Citizen in order to comply with U.S. government-imposed requirements related to the nature of the work and/or where it will be performed.

This position requires that the candidate selected be a US Citizen and candidates must be able to obtain and maintain a US Government security clearance of TS/SCI. Basic qualifications

Bachelor's degree in Electrical Engineering
Bachelor's degree in Mechanical Engineering, Aerospace Engineering, Manufacturing Engineering, or an equivalent field
5+ years of experience in satellite or network system design, modeling, and analysis
Strong understanding of orbital mechanics and constellation geometry, including modeling orbits, reference frames, and vector geometry to simulate the time-varying relative geometry of satellites and ground nodes
5+ years of experience developing code in MATLAB, C, C++, or Python, including industry-standard coding and regression practices
Working knowledge of RF or optical link budgets and how link performance drives system capacity and availability
Experience with resource scheduling, allocation, or optimization for a communications or satellite system (e.g. contact scheduling, link or beam assignment)
Strong written and verbal communication skills, including preparing and presenting technical content for customers and program reviews Preferred qualifications
Master's or PhD in Aerospace Engineering, Electrical Engineering, Computer Science, Physics, a related discipline, or equivalent experience
Experience with satellite constellation design and constellation management trades
RF or communications system design and modeling background, covering link-level analysis, communication theory, OFDM/MIMO, and digital/wireless communication systems
Experience with optical inter-satellite links and space-to-space access analysis
Experience with graph theory and network topology analysis
Familiarity with satellite operations, mission planning, and contact scheduling
Experience supporting government or national security programs and proposals
Experience with mission engineering or mission-level analysis, including design reference missions, CONOPS development, scenario and vignette analysis, and measures of effectivenes
