IonQ seeks a senior silicon validation engineer for its Cryo-CMOS IC team in Oxford. The role leads validation and characterisation of analogue and mixed-signal ASICs for trapped-ion quantum processors, from test planning and platform development through first-silicon bring-up, debug and system integration. Work covers room-temperature and cryogenic measurements near 4 kelvin, including bare-die probing, Python automation, validation boards and acceptance reporting. The posting expects substantial silicon-validation experience, laboratory skills, Python, PCB debugging and interfaces such as SPI, I2C and JTAG, plus mentoring and technical leadership.
