Software Engineer (.NET)

Hello! We're Teya.

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.

Become a part of our story.

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.

Your Mission

We are looking for a Software Engineer who will focus on enhancing our most-used E-commerce product—a high-traffic platform with multiple services that process over a million transactions every month. Your main priority will be maintaining, improving, and expanding this platform using C# (.NET), Java, WebMethods, and related technologies to ensure robust performance, scalability, and reliability.

You will maintain and enhance world-class E-commerce solutions that empower small and medium businesses across Europe.
