About this role

Citi is looking for a skilled Java Developer to join our Technology team and play a key role in building, maintaining, and advancing enterprise-grade shared services that underpin critical financial operations at global scale. In this role, you will design and deliver high-performance Java-based solutions within a high-throughput computing environment, working closely with cross-functional technology teams to drive application stability and reliability. This is an opportunity to take ownership of meaningful technical challenges, mentor junior colleagues, and operate as a subject matter expert within a collaborative, performance-driven engineering environment.

Responsibilities

Design, develop, and implement enterprise Java applications using Spring Boot, Apache Camel, and related open-source technologies to meet complex business and system requirements. Build and maintain messaging and integration layers using JMS, WebSphere MQ, and TIBCO EMS to support high-volume, low-latency transaction processing. Lead application analysis, performance tuning, and measurement activities to ensure systems meet reliability and throughput standards in production environments. Manage Tier 3 production support, diagnosing and resolving critical issues using tools such as Thread Dump Analyser and Memory Analyser Tool to minimize service disruption. Contribute to all phases of the software development lifecycle — from requirements analysis and design through to testing, deployment, and post-implementation review — within an Agile delivery model. Implement and recommend security measures during post-deployment analysis to protect system integrity and ensure continued functionality. Act as a technical advisor to senior stakeholders and less experienced team members, setting engineering standards and guiding development practices across the team. Assess technical and operational risk when making development decisions, ensuring solutions align with compliance requirements and safeguard the integrity of Citi's systems and clients. Required Qualifications & Skills 5+ years of hands-on experience developing and maintaining enterprise shared services, with demonstrable expertise in Java 8, Spring Boot, and MongoDB. Proficiency with messaging and integration technologies including Apache Camel, JMS, WebSphere MQ, TIBCO EMS, and OSGi, applied within large-scale, high-transactional environments. Practical knowledge of RESTful API development, SSL, and Git-based source control workflows. Working knowledge of containerization technologies, including Docker and OpenShift, for deploying and managing application workloads. Experience operating within Agile development lifecycles, including sprint planning, iterative delivery, and continuous integration practices. Proficiency with DevOps tooling, including GitHub, uDeploy, and SonarQube, to support build automation, deployment, and code quality management. Solid SQL knowledge with the ability to query, analyse, and troubleshoot relational data sources effectively. Bachelor's degree in a relevant field or equivalent practical experience. Beneficial Skills & Qualifications Familiarity with critical-situation diagnostic tools such as Samurai and Thread Dump Analyser (TDA) for advanced JVM troubleshooting. Hands-on experience with Linux command-line administration, particularly on Red Hat Enterprise Linux (RHEL) environments. Prior experience with Lightspeed CI/CD pipelines or equivalent enterprise deployment platforms.

What We Offer

At Citi, you will work on technology that directly supports global financial services at scale. Our Technology teams operate in a collaborative, results-oriented environment where engineers are empowered to solve complex problems, develop their expertise, and make a tangible impact on systems used by clients and institutions worldwide. A hybrid working model with 3 days in the office and 2 days working remotely, giving you flexibility alongside meaningful in-person collaboration.
