Java Engineer (Microservices / Cloud / Kafka)

Contract Opportunity - initially until 31 Dec 2026 with the potential to extend for 12-months Join a high-performance engineering team building mission-critical platforms that power real-time communication across a global banking ecosystem. This is not a maintenance role — you’ll design, scale, and optimise systems that operate at enterprise scale with cutting-edge technologies. What You’ll Do: • Design and build high-performance microservices powering enterprise communication platforms handling millions of real-time interactions daily. • Lead complex system design, translating business requirements into scalable, resilient, production-ready architecture across distributed environments seamlessly. • Solve deep legacy system challenges, debugging complex production issues and optimizing performance under high throughput conditions. • Drive engineering excellence through TDD, CI/CD pipelines, clean architecture, and enforcing best practices across teams consistently. • Collaborate with stakeholders, architects, and product teams to deliver innovative solutions aligned with business and technical goals. What We’re Looking For • Expert in Java, Spring Boot, Microservices, with strong experience building scalable distributed systems in production environments. • Deep understanding of Kafka, messaging systems, event-driven architecture, and real-time data streaming at enterprise scale systems. • Strong computer science fundamentals including algorithms, data structures, and object-oriented design with practical application experience. • Hands-on experience with Docker, Kubernetes, CI/CD pipelines, and cloud-native deployment in complex environments production systems. • Proven ability solving complex technical problems, optimizing performance, and handling high-pressure production incidents effectively independently. You’ll work on a centralised, high-performance messaging platform integrating SMS, Email, Push, and real-time chat across the bank. Built using Spring WebFlux, Kafka Streams, Apache Camel, Kubernetes, and modern reactive architecture — this is engineering at serious scale. You’re not just coding — you’re re-architecting legacy systems, building event-driven platforms, and shaping the future of digital banking communication. Hiring Bar (Read Carefully) • First round includes a high-intensity Codility test — only top engineers will pass • We are hiring experts, not learners — strong fundamentals and real-world system design experience are non-negotiable If you want to solve real engineering problems at scale—not just ship features—this role delivers unmatched technical depth and impact. You’ll work with elite engineers, modern tech stacks, and systems that truly challenge your capabilities. Apply now if you’re ready to prove you belong among the top engineers.
