Who we are?

TransferWise was founded in 2011 with a clear mission: Money without borders - so people and businesses can send and receive any currency effortlessly, whenever, wherever.

Sure, the heart of what we do is international money transfer. And we’re committed to making it instant, convenient and fair for millions of people, all over the world. But we’re growing our other products and our teams at an exciting pace. And we’re looking for the very best to jump on board.

What it’s really like to work here?

At TransferWise, we do things a bit differently. There’s no corporate nonsense and no old-fashioned hierarchy. Instead, we work in dozens of self-sufficient, autonomous teams. Think of them like start-ups within a start-up that learn from each other.

Each team picks the problems they want to solve. So there’s no micro-management. No hiding behind fancy job titles. And no one telling you what to do. You are your own boss. But you’ll get tons of guidance and plenty of support from talented, super-smart colleagues from all over TransferWise.

We’re going to be upfront - the way we work doesn’t suit everyone. But if freedom, autonomy, and life-affirming, head-scratching professional challenges rock your world, we could be a match made in heaven.
