Principal RF Engineer II

CesiumAstro•Melbourne, FL

1d•Hybrid

About The Position

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 pride ourselves on a dynamic and cross-functional work environment that fosters learning, development, and engagement. We are seeking a passionate, collaborative, energetic, and forward-thinking Principal RF Engineer II with extensive experience in board-level and system-level RF electronics design. If you thrive in a startup environment and are passionate about developing leading-edge phased arrays for satellites, spacecraft, and aerospace systems, this role is for you. You will be responsible for RF circuits, modules, and systems throughout all phases of the development process, demonstrating proficiency in board-level schematic design, PCB layout of RF circuits, system-level communications concepts (like link budgets and modulation schemes), and end-to-end RF product development. The work encompasses various 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 oversee 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 include block diagrams, detailed schematics, PCB layout and routing, simulations, and test design. Principal Engineers also serve as technical and professional mentors and may lead company programs. The successful candidate will present engineering design review materials to customers and the executive team and participate in proposal-writing efforts. Excellent written and verbal communication skills are essential. This role will initially be remote, with a planned transition to in-person work once the Florida office is established.
