56000 EUR per yearly Unbefristet Vollzeit Our Vision

At Cardmarket, people come first.

Our goal is to create a workplace where everyone feels safe, appreciated, and inspired. A place where you enjoy coming to work and feel good about heading home at the end of the day.

Open communication is at the heart of our culture. Only by talking openly about challenges, big or small, can we find solutions together. Cardmarket connects people across continents, regardless of skin colour, origin, religion, nationality, gender, or sexual orientation. We treat everyone equally and expect the same from all applicants. Our strength lies in our diverse perspectives and the shared commitment to move forward together as an inclusive team.

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.That's exactly what you'll find at Cardmarket. * Your everyday work You will work in a full-time position (39 hours per week) at our office in Berlin, 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 believe that great results are achieved where people feel seen, heard, and valued. 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 continuously challenge ourselves. * Vacation & further benefits 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. That's 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.
