Apply for this job 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

As a Senior Java Engineer, you will be a core contributor to our distributed financial platform - going beyond coding to actively shape architecture, drive engineering excellence, and help build systems that are scalable, observable, and regulation-ready. 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

What You’ll Do

- Design and develop high-load, distributed backend services for financial operations

- Work on core payment flows, callbacks, reconciliation, and transaction lifecycle management

- Participate in architecture discussions and contribute to system design decisions

- Implement observability across services - logging, metrics, and distributed tracing

- Improve system reliability, fault tolerance, and overall platform resilience

- Drive code quality, testing strategy, and engineering best practices across the team

- Contribute to the platform's evolution toward AI-assisted and data-driven capabilities

- Collaborate closely with Product, DevOps, and Architecture teams

What We’re Looking For

- 6+ years of strong, production Java experience

- Deep expertise in the Spring Boot ecosystem

- Solid understanding of distributed systems and microservices architecture

- Experience building high-load or financial systems - payments, banking, or fintech

- Strong REST API design skills and hands-on experience with messaging systems

- Solid SQL skills; PostgreSQL experience preferred

- Familiarity with cloud environments, CI/CD pipelines, and observability tooling

- Comfortable working asynchronously in a distributed, international team

- Clean Code mindset - SOLID principles, maintainability, and genuine ownership

Nice to Have

- Exposure to Open Banking or regulated payments environments

- Experience with Camunda or other workflow orchestration engines

- Understanding of PCI DSS compliance requirements

- Experience with event-driven or event-sourcing architectures

- Interest or hands-on experience with AI/ML applied to backend systems

What You’ll Get

- Competitive, market-aligned compensation - discussed openly at first interview

- Direct impact on architecture and strategic platform decisions from day one

- A real fintech platform running at production scale - not a demo environment

- Fully remote setup with flexible hours and an international, highly skilled team

- Exposure to modern cloud-native, AI-assisted, and Open Banking systems
