Jack Junge, Designer & UI/UX Specialist

At GatewayAPI, I have really had the opportunity to strengthen my skills. When I started, I was a newbie within my profession. Luckily, I got a leader that had great confidence in my skills and invested in my 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, Operations 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 operations and also handle sales, purchasing and servicing of large customers.
