Senior Facilities Technician in Oxford

Quantum is now, and it's built here. Oxford Ionics, now part of IonQ, is pioneering the next generation of quantum computing. Using our world-leading trapped‑ion technology, we’re building the most powerful, accurate and reliable quantum systems to tackle problems that today’s supercomputers cannot solve.

Joining Oxford Ionics means becoming part of a global IonQ team that is transforming the future of quantum technology - faster, at scale, and with real world impact.

We are seeking a Senior Facilities Technician to support the safe, compliant, and reliable operation of critical facilities infrastructure across laboratory, cleanroom, and technical manufacturing environments. This is a hands‑on, front‑line role responsible for executing day‑to‑day facilities operations, owning routine compliance tasks, and maintaining control of site activities. The role is expected to take direct ownership of facilities issues, ensuring they are managed through to resolution. The position works closely with the Head of Facilities and is critical in ensuring that compliance, contractor control, and system reliability do not rely on a single point of failure.

What You’ll Be Responsible For

• Facilities Operations & Critical Systems: Carry out planned preventative and reactive maintenance across HVAC, mechanical, electrical, and plumbing systems, supporting the reliable operation of critical utilities including Process Chilled Water (PCW), Chilled Water (CHW), HVAC systems for controlled environments, and basic gas and utility distribution systems. Act as a first responder to facilities faults and system issues, taking ownership through to resolution via fault finding, diagnostics, and escalation where required. Complete routine compliance activities and ensure effective system performance and safety.
• Compliance Ownership (Day-to-Day Execution): Take ownership of daily compliance tasks including fire alarm and life safety testing, Legionella control checks (L8), safety inspections, and basic statutory checks. Maintain accurate, audit‑ready records, support audits, and ensure documentation is complete, structured, and accessible. Proactively identify and raise compliance risks.
• Contractor Control & Permit-to-Work: Manage and control contractor activities on site, ensuring RAMS are reviewed and followed and Permit-to-Work systems are correctly applied. Ensure all works are carried out safely and to required standards, challenging unsafe practices where necessary and stopping work if required. Ensure all documentation, certification, and completion records are accurately captured.
• Laboratory, Cleanroom & Manufacturing Support: Support facilities requirements across laboratory, ISO cleanroom, and technical manufacturing environments, helping maintain controlled conditions such as temperature, airflow, and cleanliness systems. Assist with installation, relocation, and setup of equipment and infrastructure, coordinating key interfaces including power, cooling, and other services for new equipment.
• CMMS, Documentation & Asset Control: Raise, track, and close work orders using CMMS, while maintaining accurate asset registers and maintenance records. Support calibration tracking and contribute to the development and continuous improvement of SOPs and maintenance procedures.
• Incident Response & Site Reliability: Respond to facilities incidents such as power loss, leaks, and system failures, taking ownership through to resolution or escalation. Support emergency response procedures, business continuity activities, and participate in an on‑call rota where required.
• General Facilities & Site Support: Carry out minor repairs and fabric maintenance, support goods‑in and logistics activities, and assist with equipment movement where required. Maintain stock levels of critical spares and consumables, supporting flexible day‑to‑day site operations.

Requirements

To be successful in this role, you will need an NVQ Level 3, City & Guilds qualification, HNC, or equivalent in Mechanical, Electrical, or Building Services, alongside 3–5+ years of experience within high‑tech, laboratory, cleanroom, semiconductor, manufacturing, or similarly regulated environments. We are looking for someone with a strong working knowledge of MEP systems and building services, experience using CMMS systems, and a solid understanding of UK compliance frameworks, including L8, fire safety, and health & safety regulations. You will need to be confident interpreting technical drawings, SOPs, and specifications, while supporting critical laboratory and manufacturing operations where uptime, reliability, and compliance are essential.

Additional experience that would be beneficial includes working within laboratory and cleanroom environments while following gowning and contamination control procedures, participating in on‑call support and occasional out‑of‑hours or weekend working, and demonstrating a strong safety mindset with the confidence to challenge unsafe acts and ensure compliance across critical facilities infrastructure and operations.

You'd Be a Great Fit With

• Experience supporting cleanroom (ISO 5–8) environments
• Experience with PCW / CHW systems or critical cooling infrastructure
• Familiarity with BMS platforms (e.g. Trend, Tridium Niagara)
• IOSH qualification or equivalent
• Experience working in audit‑driven environments (GLP / GMP)
