About Us

Diamond Light Source is the UK’s national synchrotron science facility. By accelerating electrons to near light-speed, Diamond generates brilliant beams of light from infra-red to X-rays which are used for academic and industry research and development across a range of scientific disciplines including structural biology, physics, chemistry, materials science, engineering, earth and environmental sciences.


About the Role

We have an excellent opportunity for a talented Computer Systems Administrator to join the Diamond Scientific Computing team and make a real contribution to cutting-edge science by providing cluster computing support to Diamond.

This role covers the full cluster computing stack: hardware, Linux operating systems and cluster job scheduler (currently Altair Grid Engine). These supported systems underpin scientific research at Diamond with the expected high demands in performance and availability that come with fast detectors and High-Performance Computing operating around the clock.

The main focus in this role will be to provide technical expertise on cluster computing systems but the Scientific Computing Team is responsible for all of the science-enabling computing that our researchers require to get the best results as quickly as possible. You will contribute to solving any challenges that come our way; there is no limit to what you can learn. Innovation and creativity are encouraged, as well as a desire to automate as much as possible.

Further responsibilities will include:

  • Design, development, commissioning and operational support of high-performance cluster computing systems.
  • Engaging closely with subject matter experts in a variety of technical fields to inform the development of new systems.
  • Commission new, and diagnose faults in, cluster computing systems.
  • Develop automation tools for system administration tasks.
  • Contributing to the processes and associated software development to support the design and operation of computer systems at Diamond.

A flexible approach to work is required with some out of hours working during peak times, along with occasional UK and overseas travel.

The role will be primarily working from home initially, but may include time on site for training, with a view to increasing the time spent on site over future months as circumstances allow.


About You

You will be a keen problem solver with a desire to learn new skills and technologies.

You will be educated to degree level in a computing or science subject or demonstrate equivalent working experience.

You will have experience of systems administration in Linux or Unix experience.

You will also have experience of modern computer systems; common hardware configurations and management, along with experience of common network protocols such as PXE, DHCP, DNS, CIFS and NFS.

Experience of scripting languages such as Perl or Python is desirable, as is experience of working with a cluster computing job scheduler.

You will demonstrate good interpersonal, communication and presentation skills to allow interaction with staff and facility users at all levels.


Diamond offers an exceptional benefits package to support staff in achieving a positive work/life balance. This includes 25 days annual leave plus 13 days of statutory and company holidays, along with flexible working hours and an excellent pension scheme. Staff also have access to a range of amenities on site including a nursery, cafes, a restaurant and sports and leisure facilities. A relocation allowance may also be available where applicable.
