Application Test Analyst

Key Responsibilities

• Develop test plans and test cases for each sprint release: based on functional specifications and user stories provided by the Delivery Manager, design test scripts covering happy-path scenarios, edge cases, negative tests, and critical integration touchpoints between client’s systems.
• Execute system integration testing (SIT) across all client’s platforms: Shopify Plus (e-commerce flows, checkout, integrations), Power Pages Vendor Portal (vendor workflows, D365 sync, approval routing), D365 F&SCM (financial postings, PO/GRN flows), AWS data pipelines (Bronze, Silver, Gold data completeness and accuracy), Amazon Bedrock AI agents (query accuracy, guardrail behaviour, MCP responses), Cloud & Infrastructure changes, and Cybersecurity configuration changes.
• Execute regression testing: before each production release, run the regression test suite covering previously-passed scenarios to confirm that new changes have not broken existing functionality. Maintain and update the regression test library after each release.
• Manage defect lifecycle in Azure DevOps: log all defects with clear reproduction steps, severity classification, and screenshots or log evidence; assign to the relevant specialist; track to resolution; verify fixes and close confirmed defects.
• Produce SIT summary reports for the Delivery Manager before each CAB submission: test coverage, pass/fail rates, open defects by severity, and a clear go/no-go recommendation for production deployment.
• Coordinate UAT with Singapore business users: prepare UAT test data and scenarios, walk Singapore stakeholders through test scripts, log UAT defects, and track resolution.
• Conduct POS deployment testing: validate POS configuration changes in staging/sandbox environments before Singapore IT Infrastructure & Support executes on-site; test end-to-end transaction flows, payment processing, and integration with loyalty and financial systems.
• Test API integrations between client’s systems: use Postman or equivalent to validate request/response behaviour for key integration points.
• Support performance and load testing for customer-facing systems (e-commerce storefront) ahead of peak trading periods: coordinate tooling, execute test runs, and report results to the Delivery Manager.
• Maintain test environment hygiene: coordinate with the Cloud & Infrastructure Engineer to ensure staging environments are refreshed with appropriately masked data; confirm no production PII is used in test environments.

Kualifikasi

Required Qualifications & Experience

• Minimum 4 years of software testing or QA experience, with at least 2 years in a retail, e-commerce, or enterprise application testing context.
• Demonstrable experience executing SIT and regression testing across integrated multi-system environments, not just single-application testing.
• Experience writing structured test cases and test scripts from functional specifications or user stories.
• Experience managing defects through a full lifecycle in a defect tracking tool (Azure DevOps, Jira, or equivalent); able to write clear, reproducible defect reports.
• English proficiency at B2 minimum (IELTS 6.0), written and spoken. Must be able to write clear UAT packs in plain business English for Singapore stakeholders.
• Demonstrated independence and rigour: does not sign off on testing because a developer says it works; independently verifies all claims; proactively identifies integration risk areas that developers may have missed.

Technical Proficiency

• Azure DevOps Test Plans: test case authoring, test suite management, defect tracking, test run execution and SIT summary reporting.
• API testing: Postman or equivalent, able to construct and execute API requests to validate integration endpoints.
• SQL: ability to write validation queries against client’s databases and AWS Athena Gold layer to verify data integrity after pipeline runs or system changes.
• Browser-based testing: Chrome DevTools, network inspection, and console log review for e-commerce and Vendor Portal front-end defects.
• Basic understanding of CI/CD pipelines: sufficient to identify which build or deployment introduced a defect and communicate clearly to the Delivery Manager.
• Microsoft Teams and SharePoint: defect communication, test artefact storage, and UAT coordination with Singapore business users.
