    We’ve got a cool new office in a cool new location. The Alster lake in Hamburg, northern Germany, is one of the city’s incontestable highlights. Right outside the main city center, it’s a key hub for all the city action – and the year-round picturesque photos. Needless to say, that’s why we wanted our office to look out onto these iconic Hamburg scenes.

    At justtrack, our team is built on international talent – with more than ten different nationalities contributing actively to our everyday successes and growth. Our colleagues always tell us how good they feel when they can see their hard work and ideas directly impacting our daily business, and we wouldn’t have it any other way. And because we know how hard our team works, regular team events are an absolute must for us. We’re strong believers in flat hierarchies, flexible working, and achieving that all-important work–life balance.



    We guarantee our colleagues the newest tech stack to support you with your everyday activities, whatever they may be. We also love to keep it playful and fun by organizing hackathons on a regular basis, because what better way is there to exhibit your talent to the whole team (and to eat food with them too)? And with our focus on developing new technologies for our partners and products, it only makes sense that we celebrate every single technology launch. Whether that’s with pizza or beer – or both!
