Senior Thermal Design Engineer, Hardware Development Engineer III

Senior Thermal Design Engineer, Hardware Development Engineer III

Amazon Leo is an initiative to launch a constellation of Low Earth Orbit satellites that will provide low‑latency, high‑speed broadband connectivity to under‑served and underserved communities around the world. The mission of Amazon Leo’s Government (ALG) team is to leverage existing Amazon Leo technology and provide high‑speed, low‑latency, and secure satellite broadband services to the United States and our allied government customers.

This position requires a US Citizen capable of obtaining and maintaining a US Government security clearance of TS/SCI.

• Detailed and comprehensive analysis of bus and payload subsystems, components and mechanisms.
• Support extensive architectural trades with preliminary thermal analysis on spacecraft and subsystems for orbital operational conditions and vehicle control options.
• Drive design optimizations for performance, mass, cost, in support of all system reliability (thermal) requirements through application of a range of thermal control hardware options.
• Design, analyze and select heat pipes as needed for bus and payload components.
• Develop automated scripts enabling rapid analysis updates accommodating trades (power states, duty cycles, structural mapping).
• 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 / select test equipment as needed (TVAC / thermal chambers, sensors, data logging equipment etc.) and correlate test results with mission operations models.
• Acceptance Test and Qualification planning, test simulation, and execution. Correlation of results with predictions.
• Launch Vehicle environment simulation from integration through launch.
• Document trades and design evolution, and preparation of materials for design review gates.
• Support thermal design for terrestrial equipment and systems with CFD analysis as appropriate.
