Working at IONIO – No excuses, no fuss, just go.
Ready to build the future with IONIO?
Are you technical, curious, and the kind of person who grabs opportunities instead of making excuses? Then you might be exactly who we’re looking for.
We’re not searching for people who just want “a job.” We want people who are hungry to grow, eager to learn, and ready to make a real impact.
At IONIO, everything comes down to mindset. On our wall it says: “Fuck Your Excuses.” We value doers – people who take responsibility, adapt when plans change, and prefer solving problems over endlessly talking about them.
What you can expect from us
Challenging work – no boring checklists, but real impact.
Freedom & responsibility – if you have a good idea, you get the chance to make it happen.
Room to grow – you’ll be challenged, supported, and constantly learning.
A strong team – no politics, no silos, just pushing forward together.
Great coffee – because every solution starts with one.
What you won’t find here
A 24-hour work week with a full-time salary. (If you find that, let us know – we’ll sign up too.)
Luxury company trips to tropical islands. We’d rather invest in things that actually matter.
A “yes, but” culture. Problems are there to be solved.
A place to hide. At IONIO, responsibility is real – and so is ownership.
About IONIO’s direction
The vision is clear, the goals are ambitious: IONIO is growing. In 2026, our aim is to expand to around six employees. The course is set – but the path we take? That’s something we’ll build together. With your ideas and your drive, you’ll help shape the future of IONIO.
Does this sound like you?
Then now’s the time to show what you’re made of. Forget three-page motivation letters – just prove it in practice.

A career with IONIO means the following.
Whatever job you do, at IONIO you get three things as standard: freedom, hands-on training and unlimited career opportunities.
This is because we are the only company in the Netherlands that provides test and measurement systems like we do. That means the opportunities for growth are unlimited. This means you can learn a lot and take the space to do so.
This does come with responsibility: asking questions is allowed, but taking the initiative to find answers yourself is better!
