Senior Java Backend Engineer (Kafka, Microservices, Cloud)

Are you a senior Java engineer who wants to work on something more than just another CRUD system?
Join our engineering team in Slovakia, working closely with US counterparts in a distributed, high-autonomy setup, and be part of a large-scale fintech transformation for a US client.
We are modernizing a century-old platform serving 5M+ participants, 15,000+ institutions, and $1.3T in assets — moving from fragmented, manual legacy systems to a scalable, automated, AI-enabled platform.
This is a high-impact, high-complexity engineering challenge — not a greenfield demo, but a real-world re-platforming with strict requirements on data consistency, scalability, and reliability.
You’ll work in a modern environment combining Java 21, reactive architecture, Kafka, and hybrid cloud (AWS + on-prem).

• Design and build backend services in Java (Java 21) using modern, reactive approaches
• Contribute to decomposition of a legacy monolith into microservices architecture
• Develop event-driven systems using Apache Kafka for high-volume financial processing
• Work on real-time, high-throughput systems with strict consistency and auditability requirements
• Participate in re-platforming to hybrid cloud (AWS + Kubernetes/OpenShift)
• Collaborate on automation and AI-assisted development workflows (GenAI tooling)
• Take ownership of technical solutions — from design to production
• Actively contribute to engineering best practices, mentoring, and knowledge sharing

• 4-7 years of experience in Java backend development
• Strong experience with Spring / backend frameworks and API design
• Hands-on experience with distributed systems, microservices, or event-driven architecture
• Solid understanding of data persistence (SQL + NoSQL)
• Experience with Kafka or similar messaging/event streaming platforms is a strong advantage
• Comfortable working with cloud environments (AWS preferred) and containerization (Docker/Kubernetes)
• Ability to understand complex systems and work with legacy code / unclear requirements
• Strong problem-solving mindset and ownership mentality
• English at B2+ level (daily communication in international teams)
• Slovak or Czech language proficiency (C1 – C2 level)

NICE TO HAVE
• Experience with reactive frameworks (e.g. Vert.x, WebFlux)
• Knowledge of CI/CD pipelines (Jenkins or similar) and DevOps practices
• Experience with hybrid cloud environments
• Exposure to AI-assisted development tools / GenAI
• Background in financial services or regulated environments

WHY THIS PROJECT
• Work on a system impacting millions of users and real financial outcomes
• Solve non-trivial engineering problems (data consistency, scale, event processing)
• Modern stack: Java 21, Kafka, microservices, Kubernetes, AWS
• Exposure to AI-driven development practices already embedded in delivery
• International collaboration with highly experienced engineering teams
• Long-term, stable project with real technical depth (not a short-term migration)
