QA Lead

Senior Quality Engineer / Test Lead

We are a dedicated Quality Assurance Competence Center committed to delivering high-quality software testing services across diverse industries and technologies. The Senior Quality Engineer / Test Lead is a senior hands-on quality role responsible for designing, coordinating, and executing end-to-end test coverage across complex, multi-party integration programmes. The role has a strong focus on data integration, reconciliation testing, and finance/accounting system assurance, ensuring that data flows correctly across transformation layers, integration platforms, and downstream finance systems. This role requires strong ownership, the ability to work across multiple teams and vendors, and the confidence to challenge coverage gaps, drive quality evidence, and support go/no-go decisions for business-critical releases.

Own and drive end-to-end test coverage for complex integration flows across multiple systems, teams, and vendors. Design business-critical E2E test scenarios covering customer journeys, data flows, transformation rules, finance postings, reconciliation points, and downstream accounting outputs. Lead testing activities for data integration and finance reconciliation, ensuring correctness, completeness, and auditability of data across source and target systems. Validate data flowing through transformation layers, data platforms, APIs, batch processes, event-driven integrations, and finance/accounting systems. Perform hands-on test execution where required, including SQL-based data validation, reconciliation checks, defect investigation, and evidence gathering. Coordinate with multiple delivery parties, including eCommerce, data, integration, finance, vendor, and reporting teams, to ensure agreed quality coverage is delivered. Define and manage Quality Contracts with autonomous teams, making sure ownership, scope, test evidence, and residual risks are clear. Identify test coverage gaps, integration risks, data quality issues, and reconciliation defects across distributed systems. Produce clear and defensible quality evidence to support release readiness and go/no-go decisions. Work closely with technical and non-technical stakeholders to explain quality status, risks, dependencies, and remediation actions. Support defect triage and root cause analysis across complex integration landscapes. Promote risk-based testing, data-driven validation, and continuous improvement in quality engineering practices. Contribute to quality strategy, test planning, reporting, and governance for enterprise-scale programmes.
