About this role
* Build and maintain automated data regression tests for the migration from a legacy Postgres warehouse to Snowflake: query validation, integration tests on real data, scheduled reconciliation (row counts, IDs, checksums, freshness) and monitoring of schema and data changes. * Analyse production comparison results, classify mismatches and give go / no-go recommendations for each rollout stage. * Build an API regression suite (contract or snapshot tests) for critical endpoints, running in GitLab CI on every change. * Take ownership of the existing Playwright framework: stabilise it, remove flaky tests, extend it to critical user journeys and add post-deployment smoke tests. * Learn the business domain in depth and run structured exploratory and edge-case testing (roles, markets, time zones, large data volumes, browsers). * Run non-functional tests: performance and load, fallback and rollback, tenant isolation and personal data protection. * Prepare anonymised test data and test accounts, and coordinate UAT with business stakeholders. * Report defects in Jira, retest fixes, deliver a quality report every sprint and work shift-left within two-week Scrum sprints. * At least 4 years of experience in test automation for web applications, writing code in TypeScript or JavaScript. * Strong Playwright skills (or another modern framework), including the Page Object Model. * Experience in API testing (REST, contract or snapshot tests). * Strong SQL, including reconciliation and data quality queries on large tables. * Experience testing data migrations, data pipelines or data warehouses. * Experience integrating tests into CI/CD (GitLab CI or similar) and reporting results. * A structured approach to exploratory testing and clear, precise defect reporting. * Experience with multi-tenant systems and handling personal data (GDPR). * Professional written and spoken English.
