Join our team!


Dear future colleague,

My name is Nadia Jansen and I am the proud owner and CEO of Group Jansen. Next to my family, my greatest passion in life is my business! I would like to address you personally because this personal approach is at the heart of our company and characterises how we  work. Jansen may be a large professional group but  personal advocacy - our people's passion for their job and projects - is central to everything we do.

Ambition, pride, innovation and care infuse our projects, offices, people and certainly my working day. We can laugh and party together, but our feet are firmly on the ground  #doemaargewoon). We implement projects all over the country and even abroad, but we hope that our friendly Limburg roots are one of the assets that will convince you to join  our team.

Wanted: strong people

"It is important that employees feel happy in their jobs. We are looking for people with passion, enthusiasm and a fascination for the profession. People with a positive attitude. We always have to work hard, but that doesn't mean we can’t enjoy ourselves! The 'fun factor' is very important to us: we work hard, laugh a lot and don’t take ourselves too seriously."

Nadia Jansen
CEO, Group Jansen

"In this company, we grow together in a family atmosphere that encourages everyone to perform well. The greatest challenge in my job is the wide variety of tasks in my job package. Every day is a surprise, and this keeps me alert and enthusiastic."

Danny Jacobs
Project Director, Building Group Jansen



Jansen is looking for enthusiastic people!

By this, we mean driven, positive people who are fascinated by this profession. Above  all, we want people who enjoy going to work because they are passionate about their job and enjoy a challenge. 

Jansen cares. Our projects are handled with the utmost care. We take good care of our colleagues and of ourselves! We are sporting in the broadest sense of the word. 

We want to invest in our people so that they can develop professionally and benefit from great working conditions. This is the only way we can grow as a company. At Jansen, we expect more from you – but we also insist on paying more than the market rate. We have set up an extremely ambitious well-being programme for the next few years and would be happy to tell you more about it during an introductory meeting. This positive drive that we call enthusiasm is the most important aspect for us, regardless of age, certificates, gender, ethnicity or religion.

"We werken echt samen als een team, dit is sinds Covid-19 alleen maar versterkt. Het “samen” zoeken naar oplossingen leidt steevast tot technische discussies waar altijd een gezamenlijke oplossing uit voort komt. Van het samenwerken met zo een geweldig team krijg ik energie en dit stel ik ook vast bij de medewerkers: ze zijn zeer gedreven. Het ‘out of the box’ denken doet mensen ook boven zich zelf uitstijgen. Het zijn zo’n zaken die motiveren, energie geven en zorgen voor zeer enthousiaste medewerkers in onze dynamische organisatie."

Eric Vanhees
COO, Jansen Cleanrooms & Labs

"Inside Group Jansen, we care for our employees. How do they feel at work? Where do their strengths and ambitions lie? But also: What are their needs? What do they need help with? Thanks to our conversation culture, we are able to map this out accurately: our managers meet with their employees several times a year to listen, give feedback and help them with their professional development."
