Senior QA Engineer(Data Platform Testing)

Responsibilities

• Design, implement, and maintain automated test suites across API, data workflow, and graph components, integrating them into CI/CD pipelines with quality gates (unit, static analysis/security, data quality, contract/compliance, and final integrity checks).
• Own CI/CD quality enforcement , including gated releases, automated evidence of test results, and publish blocks when validation fails (e.g., consent, schema, integrity, scoring).
• Develop automated contract and compliance checks , including schema validation, required fields mapping, TCF/consent validation, and PII‑risk checks aligned to governance requirements.
• Build and execute automated end‑to‑end API tests using tools such as Bruno, Insomnia, or Postman, validating API behaviour through API Gateway, Lambda integrations, and downstream data/graph operations.
• Build data quality monitors (nulls/ranges, volume deltas, distribution checks) and statistical tests suited to identity clusters; operationalize them as part of routine runs.
• Drift detection and score distribution monitoring for identity resolution outcomes; alerting on behavioural/statistical shifts.
• Consent and governance checks that mirror operational policies (e.g., consent‑only processing at node/edge level, version‑controlled thresholds).
• Prior testing experience with identity resolution / data science / probabilistic systems -including calibration/threshold validation and explainability.
• Familiarity with observability (alerts, dashboards) to uphold guardrails on performance, resilience, and cost visibility.
• Python, Data testing, API Testing, Reporting, Automation
• Strong CI/CD automation with gated release controls and the ability to block publication when gates fail (e.g., consent, integrity, scoring). Experience integrating automated suites into Harness CI/CD tool.
• Nice‑to‑Have Experience:
• Data‑driven SaaS platforms; regulated data processing environments
• Contract‑testing frameworks (e.g., Pact) and property‑based testing approaches
• Cloud observability stacks (e.g., CloudWatch/OpenSearch/Grafana) for pipeline and API SLOs
