Lead Solution Architect, Senior Vice President in City of Westminster

The Finance Technology Transformation program is focused on migrating existing Citi-coded platforms to Oracle SaaS, impacting accounting engines, end-to-end data flow from Front Office to BA AR, Ledger Balances, and enterprise downstream consumption. The Lead Solution Architect will be responsible for leading the design and implementation of end-to-end architectural solutions for specific domains within this program. This role will translate strategic architectural direction into detailed designs, guide development teams, and ensure technical solutions meet functional and non-functional requirements. The Lead Solution Architect will report to the Principal Solution Architect and may lead a small team of Senior Solution Architects.

Responsibilities

• Lead the design of comprehensive architectural solutions for assigned areas of the Finance Technology transformation, such as accounting engines migration, specific data pipelines (Front Office to BA AR, Ledger Balances to downstream), or reconciliation frameworks.
• Develop detailed architectural blueprints, including system integration patterns (e.g., APIs, ETL via ADTS, Pub/Sub), data models, security frameworks (e.g., layered security model, TLS 1.2 encryption), and infrastructure considerations (e.g., FastConnect).
• Apply in-depth knowledge of Oracle SaaS modules (e.g., GL, AFCS, ARCS, FCCS) to design optimal configurations and ensure effective integration within the broader architecture.
• Design strategies for integrating with and ultimately deprecating legacy systems, ensuring minimal impact to upstream and downstream applications during the migration phases.
• Lead and mentor a team of Senior Solution Architects and collaborate closely with engineering leads, product managers, and other architects to ensure architectural alignment and successful project delivery.
• Work with various stakeholder groups to gather requirements, resolve technical impediments, and communicate architectural decisions effectively.
• Ensure the creation and maintenance of high-quality architectural documentation, including design specifications, decision logs, and best practice guides.
