  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.

• 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!

• 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.

• 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.

We value diverse teams for many reasons and are happy to welcome you, no matter your nationality, ethnicity, gender, religion, disability, age, or sexual orientation. What matters to us is that you are passionate, willing to learn, and want to grow with us.

We know that self‑doubt can sometimes get in the way. If you're unsure whether you're the right fit, we'd still love to hear from you.
