Job Description

Job Title: Systems Integration & Commissioning Engineer. Location: Oxford, England, United Kingdom

Oxford Ionics, part of IonQ, is pioneering the next generation of quantum computing using world-leading trapped-ion technology; We are building powerful, accurate, and reliable quantum systems to solve problems beyond the reach of today’s supercomputers.

Responsibilities:

• Build, integrate, and commission AMO and laser-optics-heavy systems, ensuring repeatable assembly and reliable operation.
• Inspect and verify subsystems and components at various stages using tools such as optical inspection, metrology, and diagnostic measurements.
• Prepare parts and assemblies before and after integration, following careful lab handling and cleaning processes;
• Organize packaging and integration activities with internal teams and 3rd party suppliers to support build turnarounds.
• Track and report build metrics, commissioning progress, repeat issues, and reliability trends.
• Prepare test assemblies and small-scale mountings, including cabling, fibre handling/alignment, and in-house build support.
• Manage the bill of materials (BOM) to ensure builds are not blocked by missing components;
• Perform pre-deployment testing, commissioning, and failure analysis; diagnose faults, resolve issues, and capture learnings for process improvement.
• Collaborate with system scientists, engineers, and technicians to translate design intent into robust, repeatable integration procedures.

Qualifications:

• Strong foundation in experimental AMO physics with hands-on lab build experience, particularly in optics and laser systems.
• Evidence of defining integration flows, troubleshooting independently, and applying technical thinking in a hands-on environment.
• Comfort working with both internal and external stakeholders and suppliers;
• Education and experience: Master’s + 3+ years of relevant hands-on experience, or PhD in a relevant field, or adjacent PhD + ~1 year of relevant industry/lab training.

Preferred:

• Commissioning experience and familiarity with electronics or instrumentation.
• Programming or scripting skills to support lab processes.
• Exposure to cryo-adjacent hardware integration or cryogenic constraints.
• Experience with precision assembly techniques and PCB technologies, supply chain, and practical build logistics.

Benefits and instructions:

• Join a world-class team of scientists, engineers, and innovators shaping the future of quantum computing.
• Competitive salary, IonQ stock options, annual performance bonus;
• Generous annual leave, flexible hybrid working, private medical and dental insurance for you and your family.
