Technical Product Manager - Global Merchant Database

Overview

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 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.

• Support the coordination and integration of multiple new products each year, ensuring a reliable, intelligent merchant data foundation
• Champion documentation excellence, including API documentation, change logs, migration guides, and internal product RFCs

• 3+ years of experience in product management, ideally in a tech, Fintech, SaaS, or platform-oriented environment

• Solid understanding of how REST APIs work (and awareness of other integration patterns)
• Hands-on experience testing APIs using tools such as Postman or similar
• Experience working with event-driven systems and defining product-level event semantics
• Ability to reason about system design trade-offs (sync vs async, scalability, reliability) from a product perspective
