Your mission

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

• 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

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

• 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
