Engineer Mechanical Installations 

Valstar Simonis is a medium-sized consultancy and engineering firm with offices in The Hague (head office), Apeldoorn, Eindhoven and Groningen. Our colleagues work every day on the best technical solutions and jointly design healthy, circular, flexible and comfortable buildings. They proudly work on the most diverse (complex) projects, with our mission always in mind;

"We make maximum use of our knowledge for a healthy and sustainable world"

Our team in Apeldoorn, consisting of 10 experienced colleagues, is happy to welcome an energetic engineer who is ready for the next great step in his/her career.

What does a Mechanical Engineer do at Valstar Simonis?

You design mechanical installations in and around buildings and you may also develop them. You work closely with the project leaders and advisors of the various design teams within Valstar Simonis.

  • You independently carry out design work for various (complex) projects
  • You make calculations and start setting up principle diagrams;
  • You write design and specification texts (with support where necessary);
  • It often happens that our teams consist of employees from different locations, so you may take a trip to one of the other locations. Regular consultations are also held via Teams.
  • You regularly consult with BIM modellers and designers from other disciplines to give the integral design the quality that we find so important;
  • In the field of sustainability, you may need to take building surveys (for existing buildings: Energy Performance Advice (EPA), for new buildings: calculations in VABI EPA U for energy use).

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

  • You have completed an MBO+/HBO Mechanical Engineering;
  • Additional relevant training/courses are useful
  • A completed HIT diploma; it makes us super happy!
  • For writing reports, it is good if you know how to get the message across in writing. Orally you also feel comfortable enough to make your voice heard, whether it concerns substantiating your choices or giving constructive feedback within a project.
  • Maybe you can already model or you are open to following a training (Revit).

How do you want to develop within our organization?

We encourage you to shape your own development. For example, do you want to progress to the position of project manager and be able to manage all phases (VO, DO, specifications) of a project and regularly sit down with the client?
Or do you have a strong desire to specialize and do you delve into the world of the many sustainability quality marks such as energy labels, WELL and BREEAM-NL?
With the right guidance, we ensure that you can take the right steps in your career. This can be done through 'training-on-the-job' or by taking professional technical courses.
In short: we offer you an environment where you can (still) learn a lot from and with colleagues who share a great passion: technology!

What can you expect from Valstar Simonis?

  • Because we all enjoy personal contact, we regularly organize fun outings such as a staff weekend, family day or just a nice dinner;
  • Twice a year we visit one of our impressive projects with all our colleagues;
  • Complete employment conditions package including travel and home work allowance (including internet allowance for home), ample training opportunities;
  • Healthy work/life balance;
  • Flexible working hours and the possibility to work from home;
  • A medium-sized organization with short lines of communication and personal attention for each other, in which colleagues are willing to share their knowledge in order to improve together.
