What we’ll need from you:
Are you an experienced application support professional who thrives in a fast-paced, mission-critical environment and enjoys working in partnership with global colleagues? If so, we'd love to hear from you. To succeed in this role, you will bring:
Strong hands-on technical expertise across the core technology stack, including Java, WebSphere, TIBCO EMS, IBM MQ, and IBM Connect Direct.

Proficiency with application monitoring and observability tools such as Kibana, Splunk, and AppDynamics to proactively identify, diagnose, and resolve production issues.
A strong problem-solving and incident-management mindset, with the ability to perform root cause analysis, debug complex issues, and deliver timely, effective resolutions — including leveraging Citi's AI tools.
