Automation Test Engineer – Data &

• Platform Engineering Hybrid: 2–3 days per week from the Madrid/Barcelona office Contract: Long-term We’re looking for an experienced Automation Test Engineer to own Quality Engineering across data and platform engineering. This is not a Test Lead or Test Management role . You’ll be hands-on, building scalable automation frameworks, designing data validation strategies, challenging weak implementations, and creating quality gates that prevent issues from reaching production. You should be highly comfortable with Python, SQL, data testing, automation frameworks, streaming systems and cloud technologies , while actively using AI-assisted ways of working to accelerate automation and engineering productivity. Design and evolve scalable, modular, metadata-driven test automation frameworks Build automation for batch and streaming data pipelines, APIs and backend services Develop reusable data testing capabilities for: SQL assertions and reconciliation Data contracts YAML/JSON-based test configurations Proactively test failure scenarios including: Late-arriving data Validate ETL/ELT pipelines using row, aggregate and hash-based reconciliation Test incremental loads, backfills and event-processing semantics Integrate and extend Great Expectations, Soda or similar data-quality tools Embed automated quality gates into CI/CD and DataOps pipelines Work with GitHub Actions, Jenkins or equivalent Develop strategies for synthetic, masked and deterministic test data Perform performance,



stress and reliability testing across data platforms Automate security and compliance validations around PII/PHI, encryption, access control and data retention Work closely with Data Engineers, Platform Engineers and Architects to embed quality early Reduce flaky tests, false positives and unnecessary compute Use AI tools and AI-assisted engineering practices wherever possible to accelerate automation ️ Programming &
