The European Spallation Source (ESS) is poised to become Europe’s flagship neutron research facility, advancing material science with cutting-edge technology. ESS will enable groundbreaking experiments to deepen our understanding of matter and tackle pressing global challenges in energy, health, and the environment. As a European Research Infrastructure Consortium (ERIC) uniting 13 member states, ESS is completing its construction phase and transitioning to full user operations by late 2027. To drive this transformative journey, we are seeking an experienced and dynamic Chief of Staff to work closely with the ESS Director General and to lead the ESS Executive Office.

About this role:

This is a new role at ESS. As Chief of Staff, you will report directly to the Director General where you will play a central role in driving ESS’s strategic priorities within ESS’s commitment to create impact through performance built on collaboration. You will lead the Executive Office, which integrates the Governance and Compliance Office.

You will act as a trusted advisor and partner to the DG, supporting the formulation and execution of organizational goals, enabling cross-departmental collaboration, and ensuring operational oversight and follow-through on critical initiatives. Additionally, you will serve as a primary interface with ESS member states and other stakeholders, fostering strong relationships while maintaining oversight of risk management, governance, and policy development.

As ESS transitions from its construction phase to full user operations, the scope of this role will naturally adapt requiring a close alignment with the Project Directorate during the transition period.
