The benefits

Passion for languages
We’re a team of 34 people speaking 20 languages fluently between us. For those wanting to improve their German (or Denglisch!), you can join one of our German classes on us.

Take a deep dive
As a Tandem team member, we’ll give you a budget for up to 6 “Deep Dive Days” per year. 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.
