Teya is a payment and software service provider, headquartered in London serving small, local businesses across Europe. Founded in 2019, we build easy to use, integrated tools that enable our members to accept payments and boost business performance.
At Teya we believe small, local businesses are the lifeblood of our communities.
We’re here because we don’t believe there’s a level playing field that gives small businesses with a fighting chance against the giants of the high street.
We’re here because we see banks and legacy service providers making things harder for them. We don’t think the best technology or the best service should be reserved for those with the biggest headquarters.
We’re here to fight for a future where small, local businesses can thrive, and to commit the same dedication they offer all of us.
We’re looking for exceptional talent to join our mission. We offer a chance to create impact in a high-energy and connected culture, while benefiting from continuous learning opportunities, a supportive community which is proud to serve our mission, and comprehensive benefits.
Small businesses are the backbone of our communities — yet they remain underserved by traditional banks and legacy payment providers. As a Principal Backend Engineer, you will play a defining role in changing that.
Your mission is to design and build the resilient, scalable fintech infrastructure that underpins our most critical business initiatives. This isn’t about owning a single service — it’s about owning outcomes. You will drive the technical success of the platforms that power payments, merchant onboarding, transaction processing, and operational workflows across Europe.
You’ll operate at the intersection of engineering and business strategy, shaping systems that must be secure, compliant, highly available, and capable of scaling with rapid growth. The decisions you make will directly influence how quickly we can launch new products, enter new markets, and serve thousands of merchants.
This role goes beyond technical leadership. You will define and evolve the architectural foundations that multiple teams depend on, bringing clarity to ambiguity and ensuring our most important initiatives succeed.
