Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Responsible for the full development lifecycle of RF circuits and systems, from initial concept and requirements to manufacturing and in-orbit support. Tasks include designing RF front-ends, beamformers, and phased array antennas, as well as presenting design reviews to customers.
Requires a BS or MS in Electrical Engineering and at least 6 years of industry experience in RF electronics design and analysis. Proficiency with simulation tools like CST/ADS, EDA tools like Altium, and standard RF lab instrumentation is essential.
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 Senior RF Engineer II to our team. The ideal candidate has experience in board-level RF electronics design. 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.
In this position, you will be responsible for RF circuits 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, and system-level communications concepts such as link budgets and modulation schemes. 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 Cesium hardware team member, you will be responsible for RF hardware designs from initial concept through requirements 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.
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.
\nJOB REQUIREMENTS AND MINIMUM QUALIFICATIONSCesiumAstro considers several factors when extending an offer, including but not limited to, the role and associated responsibilities, a candidate’s work experience, education/training, and key skills.
Please be aware that many roles will be subject to both security and export control restrictions. These restrictions mean that factors including new starter’s nationality, any previous or dual nationalities held, place of birth and country of residence may limit those roles that you can perform for the organisation.
Please note: CesiumAstro does not accept unsolicited resumes from contract agencies or search firms. Any unsolicited resumes submitted to our website or to CesiumAstro team members not through our approved vendor list or Talent Acquisition will be considered property of CesiumAstro, and we will not be obligated to pay any referral fees.
