Lead a Knowledge Transfer Partnership project to commercialise an optical atomic clock, working across CPI TMD Technologies and the University of Sussex. Day to day involves reviewing and redesigning atomic clock subsystems, sourcing components and suppliers, and testing, characterising and integrating the full system through a gate-stage new product introduction process.

University of Oxford · Oxford · £39,424 – £47,779 pa

Builds machine learning models and digital twins of quantum devices to study how scaling affects the control and stability of quantum operations. Models the physical and control architecture to identify design bottlenecks and optimisation strategies, using simulators as a testbed for engineering trade-offs. Works with academic teams, industrial partners and national labs within the QCI3 initiative.

PsiQuantum · Warrington · £50,000 – £56,000 pa

Mechanical design role focused on precision hardware for optical quantum computing, covering enclosure and packaging design, thermal management, simulation and validation. Works closely with photonics, systems and architecture teams plus external suppliers, taking concepts from prototype build toward manufacturable systems.

IonQ · Oxford

Owns full-chip mixed-signal modelling and verification for cryo-CMOS ASICs used in trapped-ion quantum processors, building Verilog-A/AMS and real-number SystemVerilog models correlated against schematic and measured silicon. Leads AMS methodology, sign-off criteria and reviews, runs Cadence AMS/Xcelium-Spectre co-simulation and regressions, and mentors engineers through tape-out and silicon bring-up.
