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.
The Skylark product line is focused on the rapid design, build, and test of cutting-edge active phased array antennas (AESA) for terrestrial and airborne applications. Current programs span high-power, large-scale ground terminals for missile defense to commercial airline and helicopter connectivity solutions.
We are looking to add a Staff Antenna Design Engineer to our team. The ideal candidate has experience in designing, simulating, building, and testing high-frequency antennas made in printed circuit board (PCB) processes. If you enjoy working in a startup environment, and are passionate about developing leading-edge RF hardware for satellites, spacecraft, and aerospace systems, we would like to hear from you.
As a CesiumAstro hardware team member, you will be responsible for antenna designs from initial concept through requirements definition, topology selection, detailed design, analysis, optimization, manufacturing, testing, qualification, and in-orbit support of CesiumAstro's products. The work will include many aspects of phased array communication systems, including RF front-ends, beamformers, power dividers, and phased array antennas.
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.
