Thermal Design Engineer, Amazon Leo (Satellites)
Job Description
Amazon Leo is Amazon’s low Earth orbit satellite network. Our mission is to deliver fast, reliable internet connectivity to customers beyond the reach of existing networks. From individual households to schools, hospitals, businesses, and government agencies, Amazon Leo will serve people and organizations operating in locations without reliable connectivity. 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. We're looking for a Thermal Design Engineer who combines superb technical, research and analytical capabilities with a demonstrated ability to get the right work done quickly and effectively. This person must have experience working in spacecraft design, producing top notch thermal analysis and providing essential thermal related input and recommendations to vehicle architects and subsystem leads. Key job responsibilities - Support extensive architectural trades with preliminary thermal analysis on spacecraft and subsystems for orbital operational conditions and vehicle control options. - Perform from conceptual to detailed analysis of Bus and Payload subsystems, components and mechanisms. - Develop automated scripts enabling rapid analysis updates accommodating trades (power states, duty cycles, structural mapping). - Design, analyze and select heat pipes as needed for bus and payload components. - Define and execute test setups for thermal cycling and TVAC tests for development and qualification testing at subsystem and vehicle level, and correlate test results with mission operations models. - Define and select test equipment as needed (e.g., sensors, data logging equipment etc.) - Perform thermal model correlation using test results. - Conduct testing of prototypes and engineering models for fast design feedback loops. - Plan and execute characterization, qualification and acceptance tests. - Document trades and design evolution, and preparation of materials for design review gates. - Support thermal design for terrestrial equipment and systems with CFD analysis. About the team Amazon Leo’s Thermal Team is responsible for the thermal design solutions for all components in Amazon Leo’s satellites and customer terminals. We work together with many engineering disciplines (e.g., mechanical, power, electrical, network, manufacturing) to find the design that maximizes performance while minimizing mass, cost, and manufacturing complexity, and enabling all components to operate reliably over the satellite’s target lifetime. The team follows all hardware components from conceptual design, detailed analysis, development testing, through launch and flight.
