Hello. We’re Teya.
Teya was founded on a simple belief: local businesses deserve better.
They are the cafés, restaurants, salons, shops and entrepreneurs that bring character to our high streets, create jobs and keep communities moving. Yet for too long, financial services has made life harder for them - with clunky tools, poor support and complexity that gets in the way of running a business.
Teya exists to change that.
We’re building a financial platform for local businesses across Europe - one built around simple tools, thoughtful design and real human support. Our Members rely on us to help them run their business with confidence, and that responsibility shapes the way we work.
We move fast. We care about quality. We stay close to the detail. And we believe great performance and genuine hospitality should go hand in hand.
If you want to build meaningful products, solve real problems and make a genuine difference for local businesses, we’d love to hear from you

- Develop and maintain GraphQL schemas, resolvers, and API integrations, ensuring consistency between frontend requirements and backend data models while promoting type safety and end-to-end reliability.
- Write clean, maintainable, and well-tested code across the stack, applying strong TypeScript practices and contributing to overall system stability, security, and scalability.
- Actively participate in code reviews across frontend and backend contributions, helping establish engineering best practices in a team transitioning from a mobile-first to a full stack, web-capable organization.
- Identify and resolve performance bottlenecks, data inefficiencies, and production issues across the full stack, ensuring a smooth, reliable experience for merchant users.
- Stay up-to-date with the latest frontend technologies, trends, and best practices, applying them to enhance our merchant-facing web platform.
