Jobs at Oxford Ionics

The Photonic Layout Engineer will design and layout photonic integrated circuits for quantum computing, collaborate with scientists and engineers, and produce photonic layout files using Python scripts.

Support and maintain classical IT infrastructure for quantum hardware builds and operation: servers, OS provisioning, lab networks, device integration, urgent troubleshooting, and automation/documentation to improve repeatability.

Lead a small Oxford-based Quantum Systems IT team to own classical infrastructure for quantum system builds. Responsibilities include Linux server provisioning, PXE/OS configuration, IPMI/BMC access, lab network design (switches, VLANs, firewalls), integrating bespoke scientific hardware, documenting and automating processes, and coordinating handoffs with DevOps, reliability, physics and corporate IT. Hybrid Oxford role with some travel for system handoffs.

Lead a team of operating physicists to maintain and improve IonQ's commercial quantum computing fleet. Own fleet operations, incident management, deployments, operational readiness, KPIs, spares and inventory, cross-functional collaboration, and reliability engineering to improve performance, throughput, and resilience.

Lead transfer pricing strategy and documentation for non-Americas entities, support direct tax compliance and global tax provision under US GAAP, monitor international tax developments (Pillar Two, withholding, PE risk), partner with Finance, Legal and Treasury to build scalable processes, and identify automation and data tools for transfer pricing and international tax workflows.

Develop and maintain advanced UVM/SystemVerilog verification environments for complex FPGA designs. Define and execute verification plans with constrained-random testing and coverage analysis. Collaborate with RTL designers to debug issues, build automated regression suites, and integrate continuous verification into CI pipelines to ensure reliable quantum control systems.

As a Senior Physicist in System Operations, you'll manage quantum computing systems, focusing on operation, maintenance, and process improvement, while supporting commercial and development environments.

Design, code, run and analyse experiments to validate and optimise trapped-ion quantum computers. Prototype control and cooling schemes, calibrate and benchmark gates and circuits, validate trap technologies, and document results to improve system performance.

Responsible for designing and developing FPGA features for quantum systems, including logic design, simulation, verification, and firmware testing.
