Capellen
Posted on: May 29 2026
Your Work Context

Jan De Nul Group focuses on complex projects and offers customers, private or public, a total tailor-made package. Safety and quality are central to this. Our technical expertise and years of experience ensure that we belong to the absolute top. The largest lock in the world in Antwerp, an innovative quay in Panama, the sustainable and architecturally sophisticated Résidence Palace in Brussels or the integral A11. All Jan De Nul Group!

As an administrative assistant, your structured and determined approach will ensure that our construction projects run seamlessly. In Liège, you will be involved in the construction of a prestigious new building project. Will you be part of it?

Your Role

Administrative confidant of the site manager

From the site, you will help manage the operation of this major construction project. You are responsible for the administrative and organisational support of the site team - think management, project and site managers.

You work closely with the site manager and therefore have a crucial role, because without your support, our employees and subcontractors on the site cannot get to work.

Your responsibilities:

  • You welcome employees on site, make sure they have the necessary access badges and refer them to the right contact person.
  • You ensure that subcontractors have the right documents and insurance to work on site.
  • You take care of the digital and physical filing of site documents, delivery notes, etc.
  • You follow up the invoicing administratively and manage the approval flow.
  • You order site and office equipment and ensure it arrives on site on time.
  • You provide various forms of administrative support to the site managers.

You can learn 'on the job' thanks to your close cooperation with the site manager and your many contacts with other employees.

What do you need to have?

  • You speak French fluently. Knowledge of Dutch and/or English is a plus.
  • A first work experience is certainly a plus, as you will bear a lot of responsibility in a large project. But you can also convince us without work experience.
  • Your clear communication style enables you to create order in an often complex working environment.
  • You will have a lot of independence and will use it to ensure that everything runs as smoothly as possible on site.
