Why us?
Imagine a workplace where passion, trust and personal responsibility are part of everyday working life.
A place where people enjoy coming together, sharing ideas, laughing together — while at the same time working with a high level of professionalism.

You will work in a full-time or part-time role (32 hours per week up to 40 hours per week) at our office in Berlin Prenzlauer Berg — a place where creative energy, exchange and focus come together. At the same time, we offer a hybrid working model and provide you with all the equipment you need for your work.
Thanks to flexible working hours with clearly defined core hours, you can structure your day in a way that allows work and private life to harmonize well.
- Community & Culture
We meet each other as equals. An informal, first-name culture is a given, from interns to management. We belive that great results are achieved where people feel seen, heard and valued.
We foster a collaborative team environment where we leverage our collective strenghts to ensure mutual success.
We also promote a constructive error culture that encourages openness, learning, and continuous improvement. Mistakes are seen as opportunities to grow, reflect, and improve together.
Our shared passion for trading card games connects us at work and beyond. It symbolizes what defines us: curiosity, strategy, teamwork, and the drive to continuosly challenge ourselves.

Five weeks of paid vacation as well as a Germany-wide public transport ticket (Deutschlandticket) that supports you flexibly in your everyday life.
A lunch allowance (up to €7.67 per working day) as well as free drinks and snacks are also part of our benefits.
- Your development matters
Standing still is not an option for us — at least not in a positive sense.
With a personal annual learning budget of €1,500, we deliberately invest in your development: conferences, courses, books, or new skills. You decide what helps you move forward.
- Mental & physical health
We know: Great performance can only happen when people are doing well.
Thats why we support you with an Urban Sports Club membership for your physical balance, our collaboration with DearEmployee which offers anonymous, professional psychological support, and the Women of Cardmarket & LGBTQIA+ Group, which promotes exchange, visibility and empowerment.
- In short
With us, you won't find anonymous open-plan offices or rigid structures, but a work environment with heart, values, and genuine appreciation. A place where you're not only allowed to be yourself, but expected to be, take responsibility, and continue developing, professionally and especially personally.
