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
