Containerized application environments (Kubernetes, Docker)

CI/CD pipelines and release engineering infrastructure

Govern code vulnerability assessment and remediation programs , including SAST/DAST tooling integration (SonarQube, Checkmarx) and mandatory security gates in CI/CD pipelines

Liaise with Cybersecurity, Risk, and Compliance teams to address audit findings and implement security improvement plans

Delivery & Operational Excellence

Monitor and govern all phases of the software development lifecycle — analysis, design, construction, testing, and implementation — ensuring consistent quality and on-time delivery across all programs

Ensure essential procedures are followed and define operating standards and processes for the entire group

Appropriately assess risk when business decisions are made, demonstrating particular consideration for the firm's reputation and safeguarding Citigroup, its clients and assets — by driving compliance with applicable laws, rules and regulations, adhering to Policy, applying sound ethical judgment, and escalating, managing, and reporting control issues with transparency
