About Us
Peratera is a UK-based fintech company, founded in 2022 and authorised by the FCA as an Electronic Money Institution. We are building a modern, all-in-one payment platform that enables businesses to manage global payments and financial operations seamlessly.

Our solution allows companies to open multi-currency accounts, send and receive payments worldwide, and manage cross-border transactions from a single platform. Our mission is to simplify global finance and remove friction from international business operations.

You’ll drive and support the evolving Technology Vision and newly defined CTO strategy, ensure reliability, correctness and scalability of critical payment flows across the platform by combining exploratory testing with automation-first practices.

Your Tech Environment

You’ll be working in a modern, scalable tech environment built around Java (Spring Boot) and REST APIs on the backend, with React and PHP powering the frontend. Our infrastructure is hosted on AWS, and the platform is designed as a set of distributed services with multiple external integrations, including payment providers.
We follow an API-first, automation-driven testing approach, leveraging tools like Playwright to ensure high reliability and fast delivery across critical payment flows.
