JOB RESPONSIBILITIES Requirements & Product Quality AnalysisSupport the Lead Business Analyst in gathering, analyzing, documenting, and maintaining business and functional requirements.Prepare and update user stories, use cases, process flows, business rules, acceptance criteria, meeting notes, and other project documentation.Participate in stakeholder meetings, workshops, backlog refinement sessions, demonstrations, and requirement walkthroughs.Clarify open points with relevant stakeholders under the guidance of the Lead Business Analyst.Review requirements from the perspective of an end user and tester and identify unclear wording, missing information, inconsistencies, and possible edge cases.Maintain traceability among requirements, acceptance criteria, test cases, defects, and delivered functionality.Routine & Exploratory Product TestingPerform routine functional, regression, integration, usability, and user-journey testing of mobile, web, and back-office applications.Prepare, maintain, and execute test scenarios and test cases based on approved requirements and acceptance criteria.Perform exploratory testing in addition to executing predefined test cases: actively explore the system, investigate unexpected scenarios, challenge assumptions, and assess the product from the perspective of a real user.Identify negative scenarios, unusual user behaviors, boundary conditions, and combinations of actions that may not be covered by documented test cases.Ensure that new functionality, defect fixes, and critical existing processes are tested consistently in each relevant release cycle.Prepare required test data and verify that test environments are ready for planned testing activities.Document test results clearly and retain appropriate evidence of execution.Report defects with precise reproduction steps, expected and actual results, supporting evidence, severity, and business impact.Retest resolved defects and performed regression testing to confirm that changes have not affected existing functionality.Escalate critical defects, testing blockers, and quality concerns promptly to the Senior Business Analyst and project team.Domain & Regulatory ValidationValidate business logic, workflows, calculations, controls, and system behaviors against approved business requirements.Verify that relevant functionality is consistent with applicable banking, securities, and capital-markets regulations, as interpreted and confirmed by the responsible business, legal, and compliance stakeholders.Identify regulatory, operational, or customer-impact risks arising from incomplete, inconsistent, or incorrectly implemented business logic.Maintain evidence of domain-validation checks for critical product journeys and regulated processes.Data, Calculation & Integration ValidationVerify data directly in relevant databases using SQL queries and compare stored values with information displayed in user interfaces and reports.Reconcile financial calculations, balances, interest accruals, fees, transaction values, statuses, and other critical outputs against expected results.Validate data consistency and completeness across mobile, web, back-office, database, and external-system layers.Perform integration testing and verify that data is transmitted, transformed, processed, and recorded correctly between connected systems.Investigate data discrepancies and support developers in identifying their source and confirming resolution.API TestingTest REST APIs using Postman or equivalent tools as a core part of routine product testing.Validate requests, responses, status codes, authentication, authorization, validation rules, error handling, and data structures.Test positive, negative, boundary, and failure scenarios for business-critical APIs.Compare API results with database records, user-interface behaviour, business rules, and downstream-system outcomes.Maintain reusable API collections, test data, environment co
