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 actively seeking passionate, collaborative, energetic, and forward-thinking individual to join our team as a Principal RF Engineer I. The ideal candidate has extensive experience in board-level and system-level RF electronics design. If you enjoy working in a startup environment and are passionate about developing leading-edge phased arrays for satellites, spacecraft, and aerospace systems, we would like to hear from you.

 

In this position, you will be responsible for RF circuits, modules, and systems through all phases of the development process. The ideal candidate will be proficient in board-level schematic design and PCB layout of RF circuits, system-level communications concepts such as link budgets and modulation schemes, and end-to-end RF product development. The work will include many aspects of phased array communication systems, including RF front ends, frequency converters and synthesizers, filters, beamformers, power dividers, and phased array antennas.

 

As a principal hardware team member, you will be responsible for RF system and hardware designs from initial concept through requirements definition, architecture definition, part selection, detailed design, analysis, manufacturing, testing, qualification, and in-orbit support of Cesium's products. Hardware design tasks will include block diagrams, detailed schematics, PCB layout and routing, simulations, and test design. Principal Engineers also serve as technical and professional mentors in their field and may be given the opportunity to lead company programs.

 

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.
