You can look forward to

Flexible working hours: We follow a hybrid work model with 20 in-office days per quarter to foster important personal interaction while enabling a modern, flexible way of working. The remaining days can be worked from home, and you also have the option to spend up to 6 weeks per year working from countries within EU. You’ll also benefit from flexible working hours to fit your individual needs.

Individual work environment:
Design your ergonomic workspace just the way you like it – with height-adjustable desks and the laptop of your choice (MacBook or ThinkPad). If things get a bit noisy in the office, your Bose noise-cancelling headphones ensure uninterrupted focus. If needed, we can also provide you with an ergonomic chair or additional monitors for your home office.

Open work environment:
We work together in a bright, open-plan office where even the few existing doors are always open. Our teams are motivated and open to new ideas. Bring your creativity to the table and make things happen! If you need a moment of peace, you can retreat to a cozy corner of the medimops library in the break room, or recharge with a game of foosball, table tennis, or PlayStation.

Sustainability: We love second-hand and incorporate our sustainable business idea into the office routine with simple methods like using eco-friendly supplies, double-sided printing, energy-saving modes on devices, waste separation, etc. In doing so, we take responsibility and integrate sustainability into all our activities.

Training: momox is only as good as you. That's why you will find room and budget for your individual professional development with language classes, internal training, conferences, (online) courses and more.

Sport and fitness offers: During the week, you have the opportunity to take part in various sports activities. Whether it's online training, massages, or stretching at your desk – there's something for everyone. You can also get a discounted membership for Urban Sports Club or Wellhub.

Office dogs:
Our office dogs contribute to a relaxed work atmosphere and are always happy to receive some extra cuddles.

Team events:
Having fun at work and celebrating our successes together are core to our values. That’s why we regularly come together at various events to connect, get to know each other better, and strengthen our team spirit.
