Senior Thermal Engineer - Payload Systems

Application close date:

Applications will be accepted on an ongoing basis until the requisition is closed. At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We're working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight! Blue Origin is pioneering the future of space-based communications with TeraWave, a revolutionary satellite communications network designed to deliver symmetrical data speeds of up to 6 Tbps anywhere on Earth. This multi-orbit constellation will consist of optically interconnected satellites in low Earth orbit (LEO) and medium Earth orbit (MEO), providing enterprise-grade connectivity for critical operations worldwide. We are seeking a Senior Thermal Engineer to lead the thermal design and analysis of advanced phased array antenna systems for both satellite payloads and ground-based user terminals. This role is central to ensuring reliable performance of high-power, high-frequency antenna systems operating across harsh orbital and terrestrial environments, including Q/V-band and beyond. The ideal candidate brings deep expertise in thermal management of RF electronics, active phased arrays, and space-qualified hardware, along with the ability to drive cross-disciplinary design integration across mechanical, RF, digital, and power subsystems. This role offers the opportunity to shape next-generation satellite communication systems and high-performance ground terminals, enabling robust, high-capacity connectivity in increasingly demanding RF environments.
