Wise is one of the fastest growing companies in Europe and we’re on a mission: to make money without borders the new normal. We’ve got more than 13 million customers across the globe and we’re growing. Fast.

Current banking systems don’t let us send, spend or receive money across borders easily. Or quickly. Or cheaply.

So, we’re building a new one.

And we are looking for a Staff Database Engineer to join the London based team.

For our customers, using Wise should feel as simple as sending a text message. Yet behind our app and website lies a complex, one-of-a-kind engine of currencies and routes that’s being designed, built and powered by our talented teams in cities around the world. With new capabilities being built every day, there’s still a lot to figure out, and we can’t do it alone. This role is a unique opportunity to have an impact on Wise’s mission, grow as a product leader and help save millions more people money.

  • You will partner with our product teams to make datastore decisions in order to scale Wise, sitting on the pulsing vein of daily product evolution. Our almost flat organizational structure doesn't care much about titles and hierarchy and all can have their say and influence on decisions. 
  • You'll stay focused on innovation and problem solving to create happy customers. 
  • You will sit across different teams, engineers in product teams, data analysts and fellow platform engineers to work towards one unified goal – growth, keeping our data secure and accessible for times to come.

  • We expect you to be open minded and not biased towards specific technology and conduct independent evaluations and POCs on new technologies/features in order to propose the best solutions to continuously improve our customer experience.
