Job description

As a Senior Application Support Analyst, Assistant Vice President at Citi, you will take ownership of mission-critical production applications, ensuring the stability, performance, and continuous availability that global financial operations depend on. This is a senior-level role with real influence — you will act as a subject matter expert, coordinate across technology and business teams, and directly shape the reliability of systems used by traders, business users, and operations teams worldwide. If you thrive in a fast-paced environment where your technical decisions have tangible impact, this role offers the scope, autonomy, and cross-functional reach to make that count.

Responsibilities

• Manage and maintain production application environments, ensuring stability, quality, and performance consistently meet agreed service levels.
• Monitor applications continuously across the trading day, perform start-of-day health checks, execute same-day risk reconciliations, and coordinate regional handovers to maintain uninterrupted operations.
• Assess the risk and business impact of production incidents, **escalate** issues to the appropriate technology and business teams in a timely manner, and ensure resolution within service level commitments.
• Identify and implement improvements to application stability, efficiency, and effectiveness by leading or contributing to active support projects across these themes.
• Partner with development and production support teams to define scope for complex application enhancements, prioritise bug fixes, and coordinate end-to‑end release participation from testing through to deployment.
• Identify security vulnerabilities and technology risks within the current environment, communicate their impact clearly, and ensure contingency plans are in place to maintain user availability.
• Serve as a subject matter expert and point of escalation for senior stakeholders, interfacing with internal technology groups, vendors, and business users to resolve issues and align on priorities.
• Coach and mentor junior analysts, setting standards for technical documentation, operating procedures, and quality of delivery across the team.

Required Qualifications & Skills

• 6 or more years of experience in application support, production systems management, or a closely related technical operations role.
• Hands‑on experience supporting applications built on cloud infrastructure, including microservices architectures and cloud-hosted database technologies.
• Practical knowledge of messaging and event-streaming platforms such as Kafka or Solace, and experience supporting containerised application environments.
• Working knowledge of active monitoring tools used to track application health and performance in production environments.
• Ability to analyse and monitor IP network traffic, with a solid understanding of web technologies and how they interact within production systems.
• Demonstrated ability to lead within a team setting, communicate complex technical information clearly to a range of stakeholders, and plan and organise workload across multiple concurrent priorities.
• Bachelor's degree or equivalent practical experience in a relevant technical discipline.

Beneficial Skills & Qualifications

• Experience leading requirement‑gathering efforts across multiple large-scale development projects running simultaneously.
• Familiarity with storage and archiving procedures in enterprise production environments.
• Background in post‑implementation analysis and system design validation following application releases.

What we offer

• A hybrid working model with 3 days in the office and 2 days working remotely, giving you structure and flexibility in equal measure.
• Genuine ownership of production stability and improvement initiatives, with the autonomy to make decisions and drive outcomes at a senior level.
• Exposure to complex, large-scale systems across a global technology organisation, with the opportunity to broaden your expertise and deepen your specialism.
• Access to learning and development programmes that support your continued professional growth and long‑term career progression at Citi.
• Competitive compensation and a comprehensive benefits package designed to support your financial wellbeing and overall quality of life.
• A collaborative team environment where your contributions are recognised and your technical leadership shapes how the broader team performs.
