Please Note: To conform with the United States Government Space Technology Export Regulations, the applicant must be a U.S. citizen, lawful permanent resident of the U.S., conditional resident, asylee or refugee (protected individuals as defined by 8 U.S.C. 1324b(a)(3)), or eligible to obtain the required authorizations from the U.S. Department of State.
At CesiumAstro, we are developers and pioneers of out-of-the-box communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We take pride in our dynamic and cross-functional work environment, which allows us to learn, develop, and engage across our organization. If you are looking for hands-on, interactive, and autonomous work, CesiumAstro is the place for you. We are actively seeking passionate, collaborative, energetic, and forward-thinking individuals to join our team.
We are looking to add a Principal Power Electronics Engineer II to our team. If you enjoy working in a startup environment and are passionate about developing leading-edge power electronics for satellites, spacecraft, and aerospace systems, we would like to hear from you.
In this position, you will be responsible for power electronics circuits and systems through all stages of the development process. The two primary product areas for this position are: (1) optimized point-of-load converters for RF and digital modules (typically ranging from 1W to 50W), and (2) standalone dc-dc converter modules (typically 20W to 500W). Design elements and responsibilities will include isolated and non-isolated DC-DC converters, maximum power point tracking solar power converters, magnetics design and analysis, system-level power management and distribution design, point-of-load regulators, switching and linear regulators, filters, and stability analysis and measurement.
As a principal engineer on the hardware team, you will be responsible for hardware designs from concept through production, including product roadmaps, block diagrams, part selection, schematic design, PCB layout and routing, analysis, manufacturing (working with contract manufacturers), test, qualification, and in-orbit support. Principal engineers also serve as technical and professional mentors in their field.
The successful candidate will also present engineering design review materials to our customers and executive team, as well as participate in proposal-writing efforts. As such, excellent written and verbal communication skills are required.
