Who we are:

At TrueLayer, we’re building a global open banking platform that’s changing how money moves and so much more. We make payments and refunds instant, account data accessible and verification seamless — all so innovators in every industry can build better financial experiences for their users.

To date, we’ve raised $270 million from world-renowned investors including Stripe, Tiger Global, Addition and Tencent. We’ve got offices in London, Milan, Dublin and Sydney. And we’re trusted by established names like Revolut, Cazoo and Trading 212… though we’re not stopping here.

Our vision is a financial system that works for everyone. To make that happen, we’re creating original and innovative products that will remove the friction from finance for good. We’re seriously scaling our infrastructure, we’re entering new regions all the time, we’re cornering a whole new category — and we’d like your support to get us there.


At TrueLayer, we want the financial system to work for everyone — so we've made it our mission to open up access and put fintech at people's fingertips.

The Open Banking Expansion group is responsible for the systems that power our global open banking payments platform. As we continue to expand we want to build solutions that provide the best possible experience for our customers in every country we enter.

It is an exciting and challenging journey - we are looking to hire you to help us along the way.

Our challenges:

  • We want to continuously iterate and improve our offering without compromising the stability or long-term maintainability of our systems.
  • We serve millions of API requests with a 99.95% availability SLA. Our platform must remain a reliable foundation that our customers can build upon as we expand (new products, new geographies, more volume).
