Staff RF Engineer

CesiumAstro•El Segundo, CA

About The Position

CesiumAstro develops communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. The Staff RF Engineer will design and support RF circuits and systems through all phases of development, with a focus on board-level RF electronics and phased-array communication systems. The role covers RF front ends, frequency converters and synthesizers, filters, beamformers, power dividers, and phased-array antennas. As a hardware team member, the engineer will take designs from initial concept through requirements definition, component selection, detailed design and analysis, manufacturing, testing, qualification, and in-orbit support. Work includes creating block diagrams, detailed schematics, PCB layouts and routing, simulations, and test designs. The engineer will present design-review materials to customers and the executive team and contribute to proposal writing. Strong written and verbal communication skills are required. Applicants must meet U.S. Government space technology export-control eligibility requirements: be a U.S. citizen, lawful permanent resident, conditional resident, asylee, or refugee (a protected individual under 8 U.S.C. 1324b(a)(3)), or be eligible to obtain required authorizations from the U.S. Department of State.
