Process Engineer

The European Spallation Source (ESS) will soon be the world’s most powerful source of neutrons, providing researchers with unique opportunities to explore the structure of materials at the atomic level. Neutron scattering at ESS will address critical questions in physics, chemistry, geology, materials science and life science. 

About the Role: 

ESS is at an exciting turning point, transitioning from a construction site to an operating facility. To help us achieve our goal of becoming the world’s most powerful neutron source, we are seeking a Process Engineer for the Plant & Process Engineering Function, part of the Design & Engineering Division.

The group will first specify and design process systems such as cooling systems, instrument air and deionized water distribution, in accordance with PED, European harmonized codes, ESS rules and AFS regulations. They will then design the associated piping systems and mechanical supports to prepare for manufacturing, purchasing and installation phases. Finally, the group will help finalize the as-built documentation. Additional tasks include configuring and supporting the AVEVA tool suite, providing engineering review support, and offering technical advice. 

Day-to-Day you will: 

• Perform system/project preliminary design based on design descriptions and requirements:  
• Prepare specifications and reports,
