Associate - Java Developer - Lmec

**Location:** CN-Shenzhen-HyQ **Shift:** Standard - 40 Hours (China) **Scheduled Weekly Hours:** 40 **Worker Type:** Permanent **Job Summary:** The Senior Java Developer will play a key role in the strategic replacement of a legacy clearing platform by designing, developing, and delivering robust, scalable interfaces and integration services using modern cloud-native architecture principles. The role is responsible for building high-performance Java-based microservices that enable secure, resilient, and efficient data exchange across critical clearing and post-trade systems. Working within an agile engineering team, the individual will leverage technologies such as Java 21, Apache Kafka, and the OpenShift Container Platform to develop event-driven solutions, promote system decoupling, and enhance operational scalability and resilience. The role will drive the implementation of modern engineering practices, including API-first development, containerisation, automation, observability, and continuous integration and deployment. The successful candidate will collaborate closely with architects, business stakeholders, and engineering teams to ensure the target-state platform meets functional, non-functional, and requirements while supporting the organisation’s broader technology transformation strategy. They will champion best practices in software engineering, solution design, and platform modernisation to deliver a future-ready clearing ecosystem. **Job Duties:** **Responsibilities:** * Design, develop, and maintain Java-based microservices to support the replacement of the legacy clearing platform. * Build and enhance interfaces and APIs that enable secure, reliable, and high-volume integration between clearing, settlement, and downstream systems. * Develop event-driven solutions using Apache Kafka, including producers, consumers, and streaming integrations to support near real-time processing. * Deploy, manage, and troubleshoot containerised applications on the OpenShift Container Platform. * Collaborate with Solution Architects and Technical Leads to implement target-state architectures aligned with enterprise standards and cloud-native design principles. * Participate in the full software development lifecycle, including requirements analysis, solution design, development, testing, deployment, and production support. * Create and maintain RESTful APIs and service contracts, ensuring scalability, security, and backward compatibility. * Write clean, maintainable, and testable code while adhering to coding standards, design patterns, and secure development practices. * Develop automated unit, integration, and end-to-end tests to ensure solution quality and minimise production defects. * Support CI/CD pipelines by integrating build, test, deployment, and quality assurance processes within the software delivery lifecycle. * Monitor application performance, investigate production issues, and implement improvements to optimise system resilience, throughput, and latency. * Work closely with Business Analysts, Product Owners, QA Engineers, and infrastructure teams to translate business requirements into technical solutions. * Conduct peer code reviews, provide technical guidance to junior developers, and promote software engineering best practices across the team. * Produce and maintain technical documentation covering solution designs, APIs, integration patterns, operational procedures, and deployment processes. * Contribute to platform modernisation initiatives by identifying opportunities to improve architecture, automation, observability, security, and operational efficiency across the clearing technology landscape. **PERSON SPECIFICATION:** **Academic and Professional Qualifications Required:** * Bachelor's degree in Computer Science, Software Engineering, Information Technology, or a related discipline; Master's degree preferred. * Extensive experience in Java application development, with a strong track record of delivering enterprise-scale, mission-critical systems. * Strong hands-on experience with Apache Kafka, including event-driven architecture, messaging patterns, and stream processing. * Experience working within Agile delivery frameworks, including Scrum or Kanban. * Understanding of financial markets, clearing, settlement, post-trade processing, or capital markets systems would be highly advantageous. * Excellent stakeholder management, communication, problem-solving, and analytical skills, with the ability to collaborate effectively across business and technology teams. **Desirable Certifications** * Red Hat Certified Specialist in OpenShift Administration or related OpenShift certification. * Oracle Certified Professional (OCP) Java Developer. * Confluent Certified Developer for Apache Kafka. * Certified Kubernetes Application Developer (CKAD). **Required Knowledge and Level of Experience:** * Minimum 10 years’ experience in software engineering, with demonstrable lead involvement in at least one production-grade platform within financial services or a similarly regulated industry. * Proven experience designing and developing microservices-based architectures using Java and Spring Boot. * Demonstrable experience developing and deploying containerised applications using OpenShift, Kubernetes, or similar container orchestration platforms. * Experience building and supporting RESTful APIs and integration services within complex enterprise environments. * Strong knowledge of cloud-native architecture principles, distributed systems, scalability, resilience, and fault-tolerant design. * Expertise in software engineering best practices, including object-oriented design, design patterns, secure coding, and test-driven development. * Experience implementing CI/CD pipelines using tools such as Bamboo, ArgoCD, or equivalent. * Strong proficiency with source control and collaborative development practices using Git/BitBucket. * Experience with DevOps practices, including containerisation (Docker, Kubernetes), CI/CD pipelines, and infrastructure automation. * Experience working with relational and non-relational databases, including performance tuning and data integration. * Knowledge of observability frameworks, including logging, monitoring, tracing, and performance management tools. * Experience working in cross-functional teams and translating business requirements into scalable technical solutions. **Technical Skills** * Apache Kafka (KRaft Architecture) * SpringBoot * Java 21+ * Kafka Streams * Confluent Platform (desirable) * Helm Charts * Kubernetes / OpenShift * Event-Driven Architecture * Schema Registry * Kafka Connect * CI/CD Automation for Kafka Deployments * Monitoring tools such as Prometheus, Grafana * BitBucket, Bamboo, JIRA, Confluence **Company Introduction:** ITD SZ 港交所科技（深圳）有限公司，是2016年12月28日于深圳市前海自贸区成立的外商独资企业。 作为港交所的技术子公司，港交所科技（深圳）有限公司主要是为集团及其附属公司提供计算机软件、计算机硬件、信息系统、云存储、云计算、物联网和计算机网络的开发、技术服务、技术咨询、技术转让；经济信息咨询、企业管理咨询、商务信息咨询、商业信息咨询、信息系统设计、集成、运行维护；数据库管理、大数据分析；以承接服务外包方式提供系统应用管理和维护、信息技术支持管理、数据处理等信息技术和业务流程外包服务。
