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.

Collaborate deeply with product and design teams to understand the unique needs of our customer agents and translate complex operational workflows into intuitive and efficient user interfaces.
Develop robust, data-intensive UIs that handle large datasets and complex business logic, ensuring high performance and responsiveness for our internal users, leveraging TypeScript for robust type checking and improved code quality.
Write clean, maintainable, and efficient code, ensuring high performance and reliability of mission-critical internal applications, with a focus on type-safe development practices.
Actively participate in code reviews, providing constructive feedback to peers and mentoring junior engineers, particularly on effective TypeScript usage and best practices in the context of large-scale internal tools.
Identify and address performance bottlenecks and bugs, ensuring a smooth and uninterrupted experience for our customer agents.
Contribute to the ongoing improvement of our frontend development practices, tooling, and standards, with an emphasis on internal system development and type safety.
Stay up-to-date with the latest frontend technologies, trends, and best practices, applying them to enhance our back-office platforms.
Your Story:
5+ years of professional experience in frontend development.
Expert-level proficiency in TypeScript, including advanced type manipulation, generics, and understanding of complex type inference.
Strong proficiency in React.js and its core principles, developed with a type-safe approach.
Extensive experience with Next.js for server-side rendering, static site generation, and API routes, with a focus on TypeScript integration.
Solid understanding of modern JavaScript (ES6+), HTML5, and CSS3.
Experience with state management libraries (e.g., Redux, Context API, Zustand) in a TypeScript environment.
