Direct message the job poster from Vivid Technology We’re hiring on behalf of a high-growth Series B start-up that’s redefining automotive sensing. As they ramp up development and scale toward production, they’re seeking a hands-on

RF Systems Integration & Test Engineer

to join the core RF systems team. You'll play a key role in

testing and characterizing mmWave ICs

and RF subsystems - both in isolation and as part of integrated sensing platforms. Working closely with IC designers, signal processing engineers, packaging, and software teams, you'll own hands-on debug and validation work that’s critical to the company’s success. Responsibilities Lead microprobe wafer testing using VNAs, spectrum analyzers, oscilloscopes, and other high-frequency equipment to characterize new chipsets. Manage and maintain the company’s probe lab, ensuring all tools and environments are optimized for testing mmWave and mixed-signal ASICs. Develop and execute new calibration and test methods, including time-of-flight and VNA frequency extender setups. Support over-the-air (OTA) testing and integration into complete systems - from test chips to in-situ performance. Drive process automation and help scale up testing across process and temperature corners. Assist with phased array testing, analog beamforming hardware, and comparison of new PCB designs against simulation. Collaborate cross-functionally to debug system-level issues and improve end-to-end performance. Skills & Experience Strong hands-on experience with RF test equipment (VNAs, spectrum analyzers, oscilloscopes, etc.). Experience testing millimeter-wave ICs or RF systems, ideally at wafer-level and OTA. Ability to work across teams and manage your own projects and lab environment with high attention to detail. Solid understanding of RF system components such as mixers, amplifiers, phase shifters, and antennas. Degree in Electrical Engineering, or a related technical field. Nice-to-Haves Experience with phased array radar and/or analog beamforming Exposure to start-up or high-growth environments OTA testing of antenna arrays and beamforming networks Familiarity with RF system integration and validation from early testing to productisation Passion for learning and diving into new RF test methods and system design challenges Location Seniority level
