Security Mobile Developer - iOS – London

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.

Some important stuff we would like you to know

To meet our regulatory obligations as a licensed financial services company, TransferWise needs to take background checks on all new hires, which may include Criminal and Credit checks. Please discuss with the Recruiter if you have any concerns regarding this process.

At TransferWise we believe in fostering a diverse and inclusive workplace. Therefore, we want to make sure that our recruitment process is accessible to everyone. So if you need any reasonable adjustments – at any point in the process – we’ll do our best to help. Just let us know what you need on your application form or reply with your request to the email we send you after you have applied. You might need a reasonable adjustment if you’ve got a disability. Or maybe you live overseas, and you’d prefer to meet us over Skype.

Please don’t send anything to the adjustments address if you’re a recruiter, or if you’re making a speculative application. We do work with recruiters from time to time – but only through LinkedIn. And we only accept job applications when a position is actually open. So you’re better off just checking the recruitment pages regularly.
