Scientific Software Engineer for Research Software Engineering Group

The European Spallation Source (ESS) is one of Europe’s largest research infrastructure projects and is building the world’s most powerful neutron source. Through cutting-edge science and technology, ESS will enable discoveries that advance our understanding of materials, energy, health, and the environment.

About the role

The Research Software Engineering (RSE) group develops and maintains critical software systems that make neutron scattering experiments at ESS possible and successful.

As a Scientific Software Engineer, you will contribute to the development of key platforms supporting the scientific user journey, including the ESS User Portal, metadata catalogue, electronic notebook, and related scientific information systems. You will work closely with scientists, software engineers, and stakeholders across ESS to gather requirements, understand user needs, and develop robust software solutions that integrate seamlessly with the wider ESS ecosystem.

The RSE group uses modern web technologies and software engineering practices to deliver high-quality software with a long operational lifetime. In addition, the group is expanding its focus on Artificial Intelligence and Machine Learning solutions that can enhance the scientific user experience. As part of this effort, you will contribute to new AI-related initiatives and help establish RSE as a centre of expertise and development for AI applications within the Science Directorate.

This position is well suited for an experienced software engineer with a strong technical foundation, excellent collaboration skills, and a passion for building software that enables world-class scientific research.
