Senior Software Engineer [Rust]

Who we are:

At TrueLayer, we’re building the future of payments. We’re on a mission to take on outdated payment methods with a solution designed for today’s online, on-demand economy. By removing friction at the heart of commerce — the payment — we’re making it faster, safer, and smarter for everyone.

To date, we’ve raised $300 million from world-renowned investors including Stripe, Tiger Global, Addition, and Tencent. With offices in London, Milan, and Dublin, we’re trusted by industry leaders like RyanAir and Just Eat Takeaway. But this is just the beginning.

We’re reimagining how the world pays, invests, shops, and saves. We’re transforming payments for industries like e-Commerce and iGaming, redefining what’s possible with technology and innovation. Now, we’re looking for people who are ready to help us build a brand that changes an industry.

Description

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.

We’re looking for software engineers who love learning new things and working with others to solve complex customer problems. You’ll be at the heart of financial innovation, using industry-disrupting technologies like open banking, to revolutionise online payments and enable financial data to be integrated into any app or website.
