What’s the role?

As a Senior Business Analyst, you will partner closely with business stakeholders and program leadership to support the seamless migration of products, processes, and data from legacy systems to a new core banking platform. You will bridge business needs and technical solutions, ensuring the migration delivers operational efficiency, regulatory compliance, and an improved customer experience across impacted portfolios.

Additionally, you'll elicit, document, and validate detailed business requirements relating to customer data, product portfolios, and end‑to‑end workflows. You will map current‑state (AS‑IS) processes and design future‑state (TO‑BE) processes aligned with the target platform, while proactively identifying gaps, dependencies, and potential risks within migration plans.

You will act as a key liaison between business and technology teams, ensuring alignment on requirements and delivery outcomes. You will also support user acceptance testing, data validation cycles, and defect triage to ensure solutions are fit for purpose and ready for successful deployment.

What do I need?

• Extensive Senior Business Analyst experience within the banking or financial services sector, delivering large‑scale transformation programs.
• Strong expertise in customer origination, servicing, and end‑to‑end product origination processes. 
• Proven experience in customer migration initiatives, including customer‑to‑account relationships and authority migration.
• High‑level stakeholder management skills, with the ability to work across multiple business units and senior program leadership. 
• Solid understanding of data migration, validation, reconciliation, and data governance practices.
• Advanced capability in requirements elicitation, process modelling (AS‑IS / TO‑BE), gap analysis, and risk identification.
• Experience working in agile and waterfall hybrid environments, with strong knowledge of core banking products (customers, accounts, transactions, deposits, loans, payments, treasury).
