At Amazon, our tech isn't just a tool, it's your playground. Our engineers work on scalable systems, cloud services, and customer-facing products that operate at global scale. This is an environment where you learn by building. Whether you're creating cloud-native solutions, optimizing machine learning models, or building products that drive experiences for millions of customers around the globe, your work reaches the world, fast. You'll take ownership early, collaborate across teams and disciplines, and grow your skills as you tackle new problems. There's no single path forward here, with a chance to explore different directions and shape your journey as you go. This is where ambition meets opportunity and, where the impact of what you build helps define what comes next, for customers and for you. Amazon Leo is looking for an Aerospace Hardware Development Engineers to design and optimize circuitry for satellite systems and develop proof of concept prototypes for next-generation satellite hardware. This role requires close collaboration with radiation, power, mechanical, thermal, RF, and software teams. Responsibilities also include designing automated test systems, test fixtures, and factory tests, as well as leading bring-up and qualification test campaigns. This is a fast-paced, intellectually challenging opportunity to work with thought leaders in multiple technology areas. You'll have relentlessly high standards for yourself and everyone you work with, and you'll be constantly looking for ways to improve. We want individuals who want to reach beyond what is possible today. Everyone on the team needs to be entrepreneurial, wear many hats and work in a highly collaborative environment. Our team is responsible for delivering flight-qualified hardware that enables thousands of satellites to fly. As an Amazon Leo Aerospace Hardware Engineer you will work with multiple engineering teams across ground and space systems to design, analyze, build, and test hardware assemblies and components for satellite applications. Your focus will be on hardware development from concept through qualification, supporting the introduction of new generations of satellites. 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. Key job responsibilities - Design, develop, and validate hardware components, assemblies, and software solutions—from circuit boards and integrated subsystems to onboard power management systems—to determine suitability for flight. - Develop closed-loop control algorithms leveraging sensor peripherals, microcontrollers, and custom silicon, as well as innovative hardware designs and processes to optimize spacecraft capabilities. - Implement hardware design strategies to mitigate product risks to stakeholders. - Work with avionics, payload, radiation, power, mechanical, thermal, RF, and software teams to gather requirements, develop hardware architectures, determine applicable design constraints, and prepare for hardware integration. - Collaborate with responsible engineers, manufacturing engineers, software developers, tooling teams, and ground support teams to deliver flight-qualified hardware ready for launch and ensure every Leo device shipped meets requirements. - Communicate fluidly across teams to identify hardware design risks and how they will be addressed to ensure mission success. - Enable data-driven performance insights through automated test execution, collection, and analysis pipelines, including complex test automation sequences using scripting languages such as Python. - Work hands-on with hardware test equipment. - Define and execute software release processes, CI/CD, and quality verification. - Deliver clear documentation and user-focused software for engineering and manufacturing teams. About the team 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.
