Senior Software Engineer (UAS)

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.

Software helps to enable the world-leading science performed at Diamond. Our software systems facilitate operations at all levels, including the low-level control of synchrotron and beamline hardware, the planning, execution and monitor of experiments, data archiving and retrieval, data processing and visualisation, the application for beamtime, and capture of remote experiment plans and samples. Our software engineers work alongside our scientists to develop innovative and robust solutions to keep Diamond at the forefront of scientific research.
