Technology Infrastructure Architect - Senior Vice President

The Technology Infrastructure Architect is a critical role responsible for envisioning, designing, and overseeing the implementation of robust, scalable, and secure infrastructure solutions that span both traditional on‑premise data centers and diverse cloud environments (public, private, and hybrid). This position requires a deep understanding of infrastructure architecture modeling, a proactive approach to leveraging emerging technologies including containerization, and the ability to drive strategic cloud adoption while maintaining operational excellence and cost efficiency.

The architect will translate complex application and business requirements into comprehensive infrastructure designs, define enterprise cloud and containerization strategies, ensure strict adherence to architectural standards and Citi’s security posture, and lead the charge in continuous platform optimization and innovative solution delivery.

• Strategic Design & Implementation: Plan, design, and provide expert assistance in the implementation of infrastructure solutions, translating complex application designs and business requirements into highly scalable, resilient, secure, and optimized architectures across hybrid environments.
• Cloud & Container Architecture Modeling: Model sophisticated cloud and container architectures, providing specialized expertise in designing and developing the underlying infrastructure for public, private, and hybrid cloud deployments, with a strong focus on container orchestration platforms like Kubernetes.
• On‑Premise & Cloud Integration: Develop detailed infrastructure designs, including network topologies, server configurations, storage solutions, and virtualization strategies for both on‑premise data centers and major public cloud platforms (e.g., AWS, Azure, GCP).
• Application Containerization: Design strategies and architectures for identifying existing applications suitable for containerization, re‑platforming, and migrating them to containerized environments.
• Performance & Sizing: Perform comprehensive sizing and capacity planning based on business Non‑Functional Requirements (NFRs) to ensure optimal performance, resource utilization, and cost‑effectiveness for both virtualized and containerized workloads.
• Remediation & Refresh: Lead and execute initiatives for End‑of‑Vendor Support (EOVS) remediation, technology refreshes, and disaster recovery/business continuity strategies across the entire infrastructure landscape, including containerized applications.

• Technology Strategy & Leadership: Provide expert guidance and consulting on appropriate technology strategies, leveraging emerging technologies and evolving engineering practices to guide project teams and solve complex business problems.
• Application Portfolio Analysis: Analyze application portfolios to identify dependencies, common infrastructure components, and assess migration feasibility to cloud environments and suitability for containerization.
• Proof of Concept & Solution Building: Deliver proof‑of‑concept projects to validate new technologies and solutions, and build reusable cloud patterns and containerized solutions for standard web applications and other enterprise needs.
• Performance Benchmarking: Conduct application performance benchmarking and analysis to identify bottlenecks and propose architectural improvements for both traditional and containerized applications.

• Standards Definition & Enforcement: Define enterprise cloud and containerization strategies, publish, maintain, and enforce reference architectures and platform roadmaps that encompass both on‑premise, cloud, and container infrastructure patterns.
• Compliance & Adherence: Ensure rigorous alignment of all infrastructure designs and rollouts with established enterprise reference standards, CATE (Citi Approved Technology and Engineering) certified products/stacks, and regulatory requirements. Define and enforce containerization standards, including image hardening, registry management, and deployment best practices.
