Job Description

Job Title

Join a product delivery team responsible for a high-scale data ecosystem used for analytics and decisioning. This role focuses on automated validation of APIs, data transformations, and downstream reporting. You'll be hands-on in building automation that proves data correctness end-to-end—across ingestion, transformation, storage, and consumption.

What You'll Own

You will define and implement an automation approach that is data-aware—meaning your tests don't just click through UI flows; they verify data rules, lineage, and outcomes. You'll partner with engineers and data-focused stakeholders to continuously raise quality, reduce release risk, and improve observability of defects.

Key Contributions
  • Build and evolve automation that validates services, pipelines, and data outputs across environments
  • Create test strategies that cover functional risk, integration points, regression, and non-functional requirements
  • Write automation utilities for repeatable dataset setup, assertions, and environment-ready test execution
  • Execute API testing and performance baselining; identify bottlenecks and reliability risks early
  • Investigate defects using logs, queries, and telemetry; communicate root cause and reproduction clearly
  • Contribute to sprint planning, estimation, and release readiness; mentor peers in automation patterns
What You Bring
  • 5+ years in QA automation / SDET / Quality Engineering roles
  • Strong scripting ability (Python and/or Java) and experience building automation frameworks
  • Experience testing analytics, data processing, or data-driven platforms at scale
  • Advanced SQL skills and comfort validating complex datasets in relational/warehouse environments
  • Experience testing service-based architectures (REST APIs, event-driven workflows, batch/stream patterns)
  • Familiarity with CI/CD, version control, and test reporting practices
  • Bonus: exposure to IaC concepts, cloud security testing, or data governance validation
