Senior UAT Tester Core Banking Implementation

We are looking for an experienced Senior UAT Tester to support a core banking implementation. This role requires someone who is confident working hands-on in the system, executing detailed test cases, investigating issues, and working closely with the business and technical teams to validate end-to-end banking processes.

Role Responsibilities

• Execute end-to-end UAT scenarios across core banking modules, including account creation, transactions, payments, loans, deposits, and customer servicing.
• Review requirements and process flows, and convert them into clear, detailed test cases.
• Prepare and manage test data required for each test cycle.
• Carry out functional, regression, negative, and integration testing.
• Log defects with complete and accurate information.
• Analyse failed tests to understand the root cause, whether its data, configuration, mapping, or functional behaviour.
• Work closely with the project team, vendor, and business SMEs to support defect triage and ensure timely resolution.
• Validate data passed through interfaces, APIs, and reports, including basic checks using SQL (if needed).
• Provide daily updates on progress, risks, and issues.
• Ensure all test evidence is recorded accurately and kept up to date for review and sign-off.

Required Experience

• At least 5 years of hands-on UAT experience within banking or financial services.
• Solid practical experience testing any core banking platform (Temenos, Sunline, Flexcube, Finacle, or similar).
• Strong understanding of common banking products and processes (deposits, loans, payments, customer onboarding, GL postings, etc.).
• Comfortable working directly in the system and handling test execution independently.
• Strong analytical skills with the ability to investigate issues deeply and explain them clearly.
• Experience using tools such as JIRA, Azure DevOps, or HP ALM to manage test cases and defects.

Preferred Skills

• Experience validating data migration results.
• Ability to run basic SQL queries for data checks.
• Familiarity with regulatory testing requirements.
• Testing certification (e.g., ISTQB) is an advantage but not required.

What We Are Looking For

• Someone with a high level of accuracy and attention to detail.
• Strong communication skills and the confidence to work with business stakeholders.
• A proactive, organised, and structured tester who takes ownership of their work.
• Comfortable in fast-paced, multi-vendor environments.
