Senior QA Automation Engineer

-

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.
