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! The role is part of the In-Space Systems business unit, which is focused on addressing two of the most compelling challenges in spaceflight today: space infrastructure and increasing mobility on-orbit. The position is within the In-Space Systems business unit reporting to the Blue Ring Spacecraft Power Systems integrated product lead. In this role, you will be accountable for driving future In-Space Systems products and services by developing spacecraft hardware and architectures to meet our business goals. The selected candidate requires strong electric propulsion power processing design experience with an emphasis power conversion design, as well as excellent collaboration skills to work across multiple disciplines and business areas across Blue Origin. This position requires 8+ years of experience with electric propulsion power processing and/or power conversion design and a demonstrated ability to design to cost and design for manufacturing at rate. Deep understanding of electric propulsion requirements and supporting voltages, signals, filtering, and controls to support system operation. This role demands familiarity with common converter architectures (isolated and non-isolated), power filtering, converter EMI, transformer design, and power and transient analysis methods. You will contribute to innovative solutions, while demonstrating personal leadership, technical judgement and competence, and a passion for the highest technical standards partnering with engineering leadership to achieve program goals with acceptable risk.
