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.

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.

Job Requirements And Minimum Qualifications

• Bachelor of Science (BS) degree or higher in Electrical Engineering or Physics from an accredited university or institution.
• Minimum of 8 years of industry or university research experience in antenna design, analysis, optimization, fabrication, and test.
• Phased array design and development.
• Expert-level proficiency in 3D electromagnetic simulation tools such as CST or HFSS.
• Strong experience with EDA tools such as Altium.
• Hands-on experience with lab instruments such as vector network analyzers, spectrum analyzers, signal generators, and oscilloscopes.
• Excellent written and verbal communication skills.

Preferred Experience

• Antenna design in frequency bands above 20 GHz.
• Aerospace electronics design, development, and qualification.
• EMI/EMC design and mitigation techniques.
