Semiconductor Jobs in Belfast

IonQ · Oxford

Lead a three-person electronics team within the Systems group, acting as a player-coach with roughly 60% leadership and 40% hands-on design. Own the electronics roadmap for quantum systems, from schematic capture and PCB layout through board and system-level test, including mixed-signal, high-speed digital and QPU drive architecture, while moving prototypes to rack-ready production.

IonQ · Oxford

Lead 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. The role spans room-temperature and cryogenic (around 4 K) measurements on packaged parts, chip-on-board assemblies and bare die, with heavy Python automation and test PCB work.

IonQ · Oxford

Integrate all features needed to operate quantum computers into complex multi-layer chips, guiding designs from requirements through layout and tape-out. Work with scientists and fabrication engineers on ion trapping chips, handling metal-track routing and photonics/CMOS interfaces. Hybrid role, three days per week in the Oxford office.

Cambridge GaN Devices · Cambridge

Design GaN power ICs and Si gate drivers using EDA tools, covering schematic capture, RTL, analog/digital and mixed-signal simulation, synthesis, STA, PNR and AMS verification. Also develops test solutions, analyses wafer-level and packaged device data, documents designs, debugs ICs and generates IP for patent applications within a growing R&D engineering team.

Cambridge GaN Devices · Cambridge

Senior leadership role owning the packaging function for GaN power semiconductors, combining people leadership with hands-on design of wirebond, flip chip and embedded packages. Involves multiphysics simulation, supplier development, qualification testing and roadmap input, working with internal teams and overseas partners from the Cambridge office.
