About the 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.
Requirements
* 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.
