This is important to us

At Gpi we want to be the best in what we do and we can only succeed if we also get the best out of you. Our Gpi employees work as a close team and it drives us to work together and with our clients to achieve the best results.


What are your qualities and how do you get the best out of yourself? We aim to put you in the best position in our company. As a team we combine our strengths and continue to grow and develop together. This way, you can add real value and do work that matters and which is appreciated. Any good ideas on how we can do something better? We are always open to it. 

Develop yourself: from welder to CEO

Would you like to keep developing yourself? We have many opportunities for growth and development in our versatile and international company. One of our CEOs started out as a welder and several former interns now have a challenging position in our business. There are also opportunities for training and education to help you perform and develop at your best.

More than just work

Our work connects us, but of course there is more than that. We are involved with our colleagues on a daily basis and, for example, we take a walk together during the lunch break to catch up or to relax. There is also time for a game of darts or pool. Before or after work, you can exercise together with colleagues in our Gpi gym. And on Fridays there is a social gathering to end the week together.

We get to know each other during the summer barbecue, the christmas party and every year the employee association organises a trip. In previous years, this was a boat trip in the Biesbosch, buggy riding, a balloon flight and in 2019, in honour of the 25th anniversary, we went for a weekend trip to Málaga.
