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.
