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.

Your Mission

You will join at a stage where the platform is evolving fast and the right engineers will grow with it — toward Tech Lead or Staff Engineer roles.

Your Tech Environment

You will work in a modern, cloud-native stack with clear ownership and no legacy surprises:
— Backend: Java 17+, Spring Boot (Core, Security, Data, Cloud), REST APIs, event-driven services, Camunda
— Infrastructure: AWS (EKS, RDS, CloudWatch), Docker, Kubernetes, GitLab CI/CD
— Data & Messaging: PostgreSQL, AMQP / Kafka-style message brokers, event-driven architecture
— Observability: OpenSearch / ELK, Prometheus / Micrometer, OpenTelemetry (in progress)
— Integrations: Open Banking providers, banking partners, external payment systems
