Senior QA Automation Engineer

About the role

Idego Group is hiring a Senior QA Automation Engineer for a remote position based in Gdynia, Poland. The role focuses on building and maintaining automated data regression tests for the migration from a legacy Postgres warehouse to Snowflake, and on strengthening the existing Playwright framework.

Key responsibilities

• Build and maintain automated data regression tests covering 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 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.

Required profile

• At least 4 years of experience in test automation for web applications, writing code in TypeScript or JavaScript.
• Experience testing data migrations, data pipelines or data warehouses.
• Experience integrating tests into CI/CD and reporting results.
• 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.

Required skills

• Strong Playwright skills (or another modern framework), including the Page Object Model.
• API testing (REST, contract or snapshot tests).
• Strong SQL, including reconciliation and data quality queries on large tables.
• CI/CD integration (GitLab CI or similar).
