At GalaxEye Space, we are pioneering the next generation of Earth observation solutions with our cutting-edge satellite technology. As a fast-growing space-tech startup, our mission is to revolutionize the way we gather, process, and deliver geospatial intelligence. In this journey, we are people with strong hands-on experience with RF measurement equipment, troubleshooting and verification against technical requirements. Join us to become a part of an agile, high-impact team working at the forefront of space innovation. Roles & Responsibilities • Develop RF test plans, test procedures, test matrices and acceptance criteria. • Perform module, subsystem and system-level RF testing and characterization. • Measure gain, insertion loss, return loss/VSWR, P1dB, IP3, noise figure, harmonics, spurious, isolation, phase noise and frequency accuracy. • Test RF chains including T/R modules, PA, LNA, PLL/synthesizer, mixers, filters, switches, up/down converters and beamformers. • Perform RF calibration, channel-to-channel amplitude/phase verification and RF path validation. • Develop RF test setups and troubleshoot hardware, LO, clock, power and signal-chain issues. • Support integration, qualification, ATP/QTP and production acceptance testing. • Prepare test reports, failure analysis, requirement compliance and technical documentation. • Coordinate with digital/FPGA, software, mechanical, system and production teams. • Coordinate with PCB/layout engineers to ensure schematic-to-layout implementation complies with RF design and manufacturing requirements. • Guide and review RF PCB layout and routing for controlled impedance, grounding, shielding, isolation, return-current paths, RF component placement and signal integrity. • Create RF schematics in OrCAD Capture, including RF signal paths, bias networks, power distribution, control interfaces and test points. Requirements • Hands-on experience with VNA, spectrum/signal analyzer, RF signal generator, power meter and oscilloscope. OrCAD Capture schematic development and RF PCB layout review experience. • Strong understanding of RF measurement techniques and RF component characterization. • Experience in RF subsystem/radar testing and troubleshooting. • Working knowledge of ADS, MATLAB or Python is desirable. • Experience in radar, AESA, SAR, EW, satellite or other high-performance RF systems. • Experience with T/R module and phased-array RF testing is preferred. • Typical experience: 3-5 years in RF testing, RF characterization or RF system verification. Benefits • Opportunity to contribute to cutting-edge space missions. • Collaborative, multidisciplinary engineering environment. • Exposure to advanced radar, embedded systems, and spacecraft technologies.
