Day in the life

Java Developer


My name is Dieter, I’m one of the Java Developers within the team and I’ve been at Sweet Mustard for about four years. Normally, our team starts the day with a short scrum meeting in which we create a plan of attack for the day. Then we get to work! Most of the time we’re translating business requirements into a technical solution, which can be anything within our team. We’re java developers so we use the java language, of course. We implement, test, fix bugs, … Sometimes the house seems on fire, and we need to resolve something quickly and efficiently in the production. There’s a lot of variety in my work, I never live the same day twice.

I chose Sweet Mustard because I used to work at huge company. Working closely together within a smaller team was something I found incredibly nice. You know everyone here.

When Mike and Lander talked to me in my job interview about the three pillars of Sweet Mustard, which are innovating business, inspiring a community and cultivating talent, I was immediately sold on the idea of working there. It showed me that I wouldn't solely be a Java Developer to them, but I’d also be motivated to do other things and to grow as a professional. A big plus for me is that I live nearby, so I’m at work quickly and our customers are close as well. That means I enjoy a great work-life balance.

If you’re in doubt: just do it and join us! It’s a fun place to work, we have challenging projects and there’s a great atmosphere.
