Tandem is the leading global language learning community, where 10 million members in over 180 countries practice languages together.

Pick a topic you’ve always wanted to explore for your professional development that has never made it out of your backlog. Then book a cabin in the woods or whatever matches your individual learning style. *Teams who train together, stay together* We offer Urban Sports Club gym memberships to boost our team’s physical and mental health. If you prefer, we can contribute to your monthly public transport ticket instead. *It takes a team to Tandem* Bonding with our teammates outside of our normal work routine is important to us. We organize regular team events: from day trips to regular lunches, to Friday beers, summer BBQs, and board games. *Balance matters* Life isn’t just about work. We know when to snooze Slack notifications, recharge our batteries, and take time out for our personal hobbies. As we’re mostly working from home right now, it’s even more important to be able to switch off from work and relax. *Modern family* As part of our family-friendly company philosophy, we embrace flexible working hours, welcome families to our events, and love for our kids to visit the office and get a taste of life at Tandem. *Relocation without the stress* If you’re looking to relocate to Berlin, we’re ready to assist you with the infamous German bureaucracy. Many of us have been through it before, so we have plenty of tips to share. You’ll feel settled in no time. *One size doesn't fit all* Nowadays, we’re all about a flexible and modern approach to working. Whether you’d like to work from our office in the heart of Berlin-Mitte, from the comfort of your home, or even a mixture of both, we’ll contribute to your work setup.
