Our prizes
Jack Junge, Designer & UI/UX Specialists

At GatewayAPI, I have really had the opportunity to strengthen my skills. Being green within your profession, and then getting a management that has great confidence in one’s competencies and invests in one’s further development – that is worth a lot!

Tjalfe Møller, DevOps Engineer

When I started in GatewayAPI, there was a well-designed introductory course. I am a big fan of the team spirit in the office as well as the different events. I like that there is always a clear plan for the tasks and that new technologies are constantly being incorporated.

Mathias Bork Knudsen, Key Account Manager

When I joined the company, I did not quite know which direction I was going career-wise. I started out as a supporter, but quickly found out that I had a talent for sales, which I have subsequently had plenty of room to develop. Today I am in charge of sales, purchasing and servicing large customers.
