Original job description

Description

Amazon LEO is an initiative to increase global broadband access through a constellation of 3,236 satellites in low Earth orbit (LEO). Its mission is to bring fast, affordable broadband to unserved and underserved communities around the world. Amazon LEO will help close the digital divide by delivering fast, affordable broadband to a wide range of customers, including consumers, businesses, government agencies, and other organizations operating in places without reliable connectivity.

As a Sr. RF Systems Analysis and Design Engineer, you will own end-to-end modeling and performance analysis of complex satellite links and RF sub-system design, spanning modem, RF front-end, phased array, and space/ground channel models.

You will build, maintain, and validate system-level link models that drive architecture, hardware requirements, and on-orbit performance, working closely with phased array, RF communications, EMC, and calibration teams. This role blends analytical modeling, software development, and engagement with real hardware to ensure we hit stringent performance targets at scale.

Key job responsibilities

Develop and maintain end-to-end RF system and link models (3GPP style link analysis, access, and feeder links), including link budgets, impairment modeling, and performance trade studies.
Perform system-level simulations of digital phased array architectures and RF signal chains, and correlate against lab and field measurements.
Define and flow down system performance requirements (EIRP, G/T, EVM, ACLR, NF, linearity, beam metrics) to hardware, RFIC, antenna, and firmware teams.
Work with modem, waveform, and MAC/PHY teams to optimize the RF system for throughput, coverage, power, and availability across global deployment scenarios.
Build reusable analysis tools and libraries (e.g., Python/Matlab/C++) to standardize link analysis and scenario sweeps across the org.
Collaborate with test, calibration, and validation teams to design measurement campaigns that close the loop between models and observed performance.
Support architecture reviews and program decisions with clear data visualizations, dashboards, and technical documentation.
Mentor junior engineers in RF system thinking, modeling best practices, and code quality for analysis tools.

Export Control Requirement:

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.

A day in the life

You’ll collaborate with RF, software, and systems engineers, see your designs and code run on live hardware, and make daily decisions that directly affect the readiness of Leo's payload and terminal products. The systems you build will enable critical data collection, system analysis, and calibration pipelines that ensure Leo hardware performs flawlessly on Earth and in orbit.

About the team

Our team owns the full performance lifecycle of Leo’s antenna systems from early concept testing and calibration to final product release. We operate at the intersection of RF hardware, software automation, and large-scale system integration.

You’ll work closely with antenna, DSP, and system development engineers, contributing to test frameworks, manufacturing support, and performance validation. We leverage AWS tools and scalable software architectures to accelerate development, automate validation, and deliver reliable test systems used across the entire Leo organization.

If you want to work on real hardware, influence product performance, and see your work scale to millions of users worldwide this is the place to do it.

Basic Qualifications

Experience leading the design, automation, deployment, and support of large-scale infrastructure
Experience programming with at least one modern language such as Python, Ruby, Golang, Java, C++, C#, Rust
Experience with Linux/Unix
Experience with CI/CD pipelines build processes

Preferred Qualifications

Experience with distributed systems at scale
