## Description

The Associate - Java Developer - LMEC 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.

**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:**

- 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.
