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.
