- Coordinate start-of-day platform checks, continuous monitoring, and structured regional handovers, maintaining SLA adherence and clear stakeholder communication throughout the incident lifecycle via ServiceNow.
- Serve as the internal operational point of contact for client-impacting incidents, providing timely and accurate communication to client-facing teams including Client Services, Technology Relationship Managers, and Operations.
- Identify recurring incident patterns and drive structured problem management to eliminate root causes, reduce manual effort, and prevent reoccurrence across the platform portfolio.
- Improve platform observability and operational efficiency by contributing to automation and monitoring initiatives using Grafana, ITRS Geneos, and GCO — reducing the volume of manual interventions required.
- Act as subject matter expert (SME) for one or more platforms, owning operational knowledge, coaching junior analysts, and serving as the escalation point for complex issues.
- Adopt and apply AI-assisted tooling for incident troubleshooting, automated investigation, and resiliency gap detection — contributing to Citi's firm-wide intelligent operations strategy.




- Manage change management activities including release preparation, deployment support, post-implementation review, and production risk assessments to support protected and controlled platform evolution. Required qualifications & skills
- 5+ years of experience in application support, production management, or platform operations — ideally within financial services or data-intensive environments, with hands-on experience across data pipelines, reporting platforms, or client-facing financial applications.
- Active ITRS Geneos monitoring and alerting experience, including dashboard configuration and alert management at an administrator level.
- SQL proficiency sufficient to independently investigate data quality issues across relational and cloud databases.
- Demonstrated practice of ITIL-aligned incident, problem, and change management — with a structured, process-disciplined approach to production operations.
- Shell or Python scripting ability applied to the automation of operational tasks — not just theoretical awareness, but practical, working implementation.
- Experience operating within a global follow-the-sun support model, including shift handovers, on-call discipline, and cross-regional coordination.
- Bachelor's degree in Computer Science, Information Technology, Engineering, Finance, or a related discipline — or equivalent professional experience. Beneficial skills & qualifications

- Experience building or maintaining Grafana or ITRS dashboards for proactive platform monitoring.
- Domain knowledge in Securities Services, Investor Services, or Capital Markets environments.
- Exposure to AI-assisted operations tooling — including agentic triage, automated root cause analysis, or intelligent monitoring platforms.
- A track record of leading or mentoring a support team, with evidence of SME accountability and knowledge transfer in a senior operational capacity.
