? About the Role
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.
? What You’ll Be Doing
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
Schema validation and evolution
Data contracts
Lineage and freshness
YAML/JSON-based test configurations
Proactively test failure scenarios including:
Schema drift
Duplicate, missing and out-of-order events
Late-arriving data
Retries, DLQs and backpressure
High-volume and concurrency issues
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 Da
