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
- Collaborate closely with Product, DevOps, and Architecture teams
- Contribute to the platform's evolution toward AI-assisted and data-driven capabilities
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
- Clean Code mindset - SOLID principles, maintainability, and genuine ownership
- Comfortable working asynchronously in a distributed, international team
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
- Exposure to modern cloud-native, AI-assisted, and Open Banking systems
- Fully remote setup with flexible hours and an international, highly skilled team
