Lead JAVA Engineer - Innovative Fintech Platform - J13181

About the Client: Our client operates a mature, industry-backed transaction network that connects wealth management firms with major issuers. Their platform is fully cloud-native, built on AWS, and utilizes a modern containerized microservices architecture to handle high-volume order pricing and placement. The Role & Landscape: You will be joining a specialized engineering team in Hong Kong to build and scale their core backend services. This is a hands-on technical role where you will be involved in the full software development lifecycle. Architect, build, and maintain robust Java-based backend services running on Kubernetes. Design and implement RESTful APIs (OpenAPI/Swagger) and manage event-driven messaging (Kafka/RabbitMQ). Work heavily with the FIX protocol for transaction processing. Collaborate directly with the product team on new features and the operations team for CI/CD deployments. Monitor system performance and troubleshoot complex production issues. What We Are Looking For: 7+ years of professional backend development using Java. Deep expertise in the Spring framework, specifically Spring Boot. Strong practical experience with microservices and event-driven architectures (ActiveMQ, RabbitMQ, or Kafka). Mandatory knowledge and working experience with the FIX protocol. Solid grasp of modern DevOps practices, CI/CD pipelines (Jenkins, Git), and container orchestration (Docker, Kubernetes). A strong foundation in software design and enterprise integration patterns. Note: While FIX protocol knowledge is essential, a traditional banking background is not strictly required if you have the technical chops.
