You can look forward to

Flexible working hours: We work according to a hybrid model that offers you maximum flexibility while also fostering important personal connections. Whether in our centrally located office or working remotely - you and your team decide together where and when you want to work. You can arrange your working hours flexibly. For personal interaction, your team meets at least 20 days per quarter in the office, as our team days are held in person.
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.
