• Build and maintain messaging and integration layers using JMS, Web Sphere 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.

• Proficiency with messaging and integration technologies including Apache Camel, JMS, Web Sphere 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 Open Shift, for deploying and managing application workloads.
• Experience operating within Agile development life cycles, including sprint planning, iterative delivery, and continuous integration practices.
• Proficiency with Dev Ops tooling, including Git Hub, uDeploy, and Sonar Qube, 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.

• Familiarity with critical-situation diagnostic tools such as Samurai and Thread Dump Analyser (TDA) for advanced JVM troubleshooting.
