About NQCC:
The National Quantum Computing Centre (NQCC) is the UK’s national laboratory dedicated to accelerating the development and adoption of quantum computing. Headquartered at the Harwell Campus in Oxfordshire, the NQCC works across government, industry, and academia to address the engineering challenges of scaling quantum computers and to build a quantum-ready economy. Its mission is to enable the UK to solve complex societal and industrial challenges by harnessing the transformative potential of quantum computing.
The NQCC is a joint initiative of the Engineering and Physical Sciences Research Council (EPSRC) and the Science and Technology Facilities Council (STFC). It sits alongside other departments within the STFC National Laboratories and has a 10-year funding commitment as part of the National Quantum Strategy

About the Role:
The Trapped Ion Quantum Computing team is responsible for delivering trapped ion quantum computing capability at NQCC, supporting both internal system development and the wider UK quantum ecosystem.
The team’s mission is to:

• Build the capability to act as the UK’s trusted technical authority in trapped ion quantum computing
• Deliver open architecture quantum computing systems
• Provide technical appraisal of progress towards useful quantum computing

The role is suitable for candidates with strong experimental or engineering backgrounds who are looking to develop into system-level roles. You will contribute to the design and integration of trapped ion quantum computing systems, working across sub-systems and supporting platform-level performance and scaling. You will also contribute to the development of open architectures and system blueprints that shape both internal development and external collaborations.

This is a highly collaborative role, working across hardware, software, and applications teams, as well as with external partners. It offers the opportunity to influence the technical direction of a national programme while remaining closely engaged with experimental and engineering work.

• Design, develop, assemble, and optimise trapped ion quantum computing sub-systems (e.g. QPU, laser systems, control systems).
• Develop and run experiments to characterise device performance and improve qubit fidelity, stability, and scalability.
• Contribute to the integration of sub-systems into full-stack quantum computing platforms.

• Contribute to system-level design, including requirements, interfaces, and performance targets.
• Support the development of scaling strategies and system architectures.
• Explore trade-offs across sub-systems and their impact on overall system performance.

• Contribute to the development of open-architecture policy & vision documents, system definitions, and system performance reports.
• Ensure work is documented to support reproducibility and…
