Are you looking for a career move that will put you at the heart of a global financial institution? Then bring your skills in analysis, problem solving, and communication to Citi's Finance Technology Transformation program.

By Joining Citi, you will become part of a global organisation whose mission is to serve as a trusted partner to our clients by responsibly providing financial services that enable growth and economic progress.# # Team/Role Overview 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.#

* 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., Fast Connect).
* 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.# # What we'll need from youThis role requires a highly experienced architect with a proven track record in leading complex financial technology transformations. The essential qualifications and skills required include:
* Expertise in designing and implementing end-to-end architectural solutions for large-scale enterprise programs.
* Strong ability to develop detailed architectural blueprints, encompassing system integration patterns, data models, security frameworks, and infrastructure considerations.
* Deep knowledge and practical experience with Oracle SaaS modules (GL, AFCS, ARCS, FCCS) and their optimal configuration and integration.
* Proficiency in designing strategies for legacy system integration and deprecation with minimal business impact.
* Demonstrated leadership skills in mentoring architectural teams and fostering collaboration across diverse stakeholder groups.
* Excellent communication skills to articulate complex architectural concepts and decisions to both technical and non-technical audiences.
