Network Administrator

Head Office

Triodos Bank is growing and our network is essential to support the growing number of customers and colleagues. That's why we're looking for a

Network administrator (32 - 40 hours per week)

“You will keep the (sustainable) heart running and contribute to the growth of Triodos Bank!”

Our ICT infrastructure is the heart of Triodos Bank. It connects our ICT services. Important for your (future) colleagues at home and abroad, but also for our customers. As a network administrator, you and your fellow network administrators maintain the network of one of the most sustainable banks in the world. You implement innovations, solve malfunctions and you are constantly on top of everything to prevent malfunctions. Of course, we don't have to tell you that IT continues 24/7 and incidents also occur at night or during the weekend. Sometimes you therefore also work outside office hours. Triodos Bank is experiencing good growth. You therefore have a great career ahead of you.

Take action

  • independently manage and maintain our networks.
  • monitor our networks, prevent malfunctions and if they do occur, you solve them.
  • implement new functionalities, products or networks and follow new developments closely.
  • actively maintain documentation.
  • help us further and develop yourself.


This is you

To master a network in no time, to create an overview and to maintain networks, you are able to hold your own pants. You are assertive, decisive and social. You prefer to bring a good portion of entrepreneurship with you and, like us, you think it is important to contribute to a sustainable society.

Furthermore you have

  • a HBO diploma in your pocket. We are thinking of courses such as Technical Informatics, ICT Management or another IT-technical oriented course.
  • basic knowledge of Cisco. You have achieved or are in the process of obtaining CCNA certification.
  • about 3 to 5 years of work experience.
  • knowledge of firewalls and routing protocols (OSPF).
  • excellent communication skills in both Dutch and English.

Several regular moments of reflection and our systematic attention for personal development help ensure that we can make that difference together.
