About The Position

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! This role is part of the Blue National Security business unit, focused on addressing two of the most compelling challenges in spaceflight today: space infrastructure and increasing mobility on-orbit. As a power electronics engineer supporting the TeraWave propulsion team, you will play a key foundational role in the development of the Hall thruster-based propulsion systems that maneuver the TeraWave constellation satellites, as well as support the propulsion team itself. TeraWave is a satellite communications network designed to deliver symmetrical data speeds of up to 6 Tbps anywhere on Earth. This network will service tens of thousands of enterprise, data center, and government users who require reliable connectivity for critical operations. Overview: Blue Origin is seeking a highly skilled and experienced Power Electronics Engineer (Level 3) to join our team in developing advanced power electronic converters for aerospace and space applications. The ideal candidate will have a proven track record designing DC-DC converters, both with and without galvanic isolation, control algorithms, and will be responsible for all phases of product development, from requirements capture through production.
