Hysopt jobs

Guylaine – Office Manager

What made Hysopt an easy choice for me, is that you get a lot of opportunities because it’s still a growing company. Plus, we’re an international player with an innovative product, which makes working for Hysopt so interesting.

Agrim – Software Developer

As you get lots of responsibilities from the very beginning, learning opportunities are vast for a ‘fresher’. You can make changes that go into production (the actual changes to the software) from your first weeks, which is not so common in most IT companies. By taking various learning courses and attending conferences, or even getting guidance from your seniors, sharpening your skills is very much encouraged.


and counting

Kristof – Energy Engineer

I chose Hysopt because I wanted to gain in-depth knowledge in the field of heating and cooling. The fact that it’s a fast-growing and dynamic company with a young team, made my decision even easier. I even studied with some colleagues at the University of Antwerp. From day one, your own knowledge and initiative can really contribute to the company.

Brian – Partner Manager

I was attracted to the company because of Roel, our CEO and founder, himself. My conversation with him showed that the values he carries, aligned very well with mine. I didn’t need much more convincing afterwards.
Being a part of a young, dynamic team is quite incredible, and the atmosphere at the office is just great. Combined with that, if you shine as a hard-working individual, you get recognised for it and get the opportunity to develop in any direction you want.

Jeroen – Software Developer

What attracted me to Hysopt was first and foremost the scientific nature of our software, along with the versatile team and the strong focus the company has. Working on a ‘green’ product and to be able to contribute positively to society made the choice even easier.
