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. We're looking for a Thermal Design Engineer with deep technical expertise, strong analytical rigor, and a bias for action. The ideal candidate brings hands-on R&D experience in thermal analysis and hardware development, and has partnered with vehicle architects and subsystem leads to drive next generation satellite design decisions. Key job responsibilities -Investigate new thermal concepts, advanced materials (coatings), and emerging cooling methods (such as advanced liquid cooling or two-phase systems) to push technical boundaries. -Develop reduced-order models, first-principle equations, and system-level thermal architecture. -Support extensive architectural trades with preliminary thermal analysis on technologies applicable to spacecraft and subsystems for orbital operational conditions and vehicle control options. -Develop automated scripts enabling rapid analysis updates accommodating trades (power states, duty cycles, structural mapping). -Design, analyze and heat rejection technologies 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. 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. 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.
Here's how to pick the right one and stand out in your application.

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
