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.
JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS
- A Bachelor of Science (BS) or Master of Science (MS) degree in Electrical Engineering from an accredited university.
- 11 years of industry or university research experience in power electronics design, analysis, test, and troubleshooting.
- Extensive industry experience designing successful power electronics products from concept through schematic, layout, manufacturing, test, and deployment.
- Experience designing power system architectures.
- Expertise in power circuit analysis, such as worst-case circuit analysis, failure method effectivity and criticality, and reliability.
- Expert-level proficiency in electronics design (EDA) tools such as Altium.
- Expert-level proficiency in PCB layout for power circuits.
- Experience with SPICE-based circuit simulation.
- Experience with power integrity simulation tools such as Ansys or ADS.
- Extensive hands-on experience with lab instruments such as oscilloscopes, spectrum analyzers, electronic loads, and signal generators.
- Excellent written and verbal communication skills.
PREFERRED EXPERIENCE
- Experience with space electronics design, development, and qualification.
- Knowledge of EMI/EMC design and mitigation techniques.

What you need to know about the Los Angeles Tech Scene
Los Angeles is a global leader in entertainment, so it’s no surprise that many of the biggest players in streaming, digital media and game development call the city home. But the city boasts plenty of non-entertainment innovation as well, with tech companies spanning verticals like AI, fintech, e-commerce and biotech. With major universities like Caltech, UCLA, USC and the nearby UC Irvine, the city has a steady supply of top-flight tech and engineering talent — not counting the graduates flocking to Los Angeles from across the world to enjoy its beaches, culture and year-round temperate climate.
Key Facts About Los Angeles Tech
- Number of Tech Workers: 375,800; 5.5% of overall workforce (2024 CompTIA survey)
- Major Tech Employers: Snap, Netflix, SpaceX, Disney, Google
- Key Industries: Artificial intelligence, adtech, media, software, game development
- Funding Landscape: $11.6 billion in venture capital funding in 2024 (Pitchbook)
- Notable Investors: Strong Ventures, Fifth Wall, Upfront Ventures, Mucker Capital, Kittyhawk Ventures
- Research Centers and Universities: California Institute of Technology, UCLA, University of Southern California, UC Irvine, Pepperdine, California Institute for Immunology and Immunotherapy, Center for Quantum Science and Engineering
