Project supporter

Valstar Simonis consists of a club of smart engineers who want to improve the world. We happily tackle around 175 impressive projects every day. While your colleagues are busy making an impact, you focus diligently on the details and streamlining project administration. And with your sense of humor and determination, you know how to put them back down to earth every now and then.

In short: with your skills in supporting and organizing you can lift the entire team to a higher level.

Our office in The Hague employs 35 people, including the IT, HR, Marketing & Communications and financial administration staff departments; a close-knit group of colleagues who are always willing to help each other and show interest in the person behind the new colleague. 

What does a project supporter do?

  • You are the point of contact for some of our clients (particularly hospitals and universities) in administrative matters;
  • At the request of the Advisor/Project Manager, you make quotations for our clients. The content comes from the Advisor, but you put the finishing touches;
  • You know your way around Word and Excel and you help us to meet schedules and manage projects;
  • You provide agenda management for Advisors and Project Leaders; planning meetings, making (complex) agreements with external parties;

What does Valstar Simonis have to offer you?

  • A warm welcome to an organization that works seriously, but where there is certainly room for humor;
  • A role in which you can really make a difference by taking over administrative work;
  • Support for your personal growth and development. Whether it concerns on-the-job training or external courses, we help you to further expand your knowledge;
  • A salary between € 2.400 and € 2.850 gross per month, depending on your knowledge and experience;
  • Several company outings and fun drinks every year to maintain ties with colleagues from other locations.

What does the profile of an interesting candidate look like for us?

  • You are familiar with administrative processes, preferably in a similar (project) organization;
  • You have an eye for detail;
  • There is a lot to do, so if you can work 5 days a week, welcome! 4 days is also negotiable.
  • You have gained experience in a similar position, such as project supporter, office manager or secretary;
  • You are more than sufficiently skilled in Excel and Word;
  • You dare to take work off your colleagues' hands, so that they can focus on their core activities.

Even if you think you do not meet all the requirements, we still ask you to respond if you think the role suits you. We care about the personality and whether yours suits us.
