Senior QA Engineer(Data Platform Testing)

Role Overview

We are looking for an experienced Automated Tester to build and evolve a robust scalable automation capability across APIs data pipelines and our graphbased identity platform. This role spans CI/CD gating automated data and contract validation graph integrity testing performance and regression testing and full endtoend API testing within AWS. The successful candidate will ensure that our identity platform consistently meets quality compliance and operational standards.

Key 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 PIIrisk checks aligned to governance requirements.
•   Build and execute automated endtoend 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.
• Create graph integrity tests in Neo4j covering node/edge parity constraints traversal path validation merge/split detection and evidencepath reproducibility checks.
• Implement performance and resilience testing including query latency targets batch window completion for rebuilds and regression suites for every deployment.
• Contribute to operational guardrails by instrumenting monitoring alerting and costaware test strategies; collaborate with engineering to ensure predictable weekly rebuild cadence and controlled adhoc extracts.

API Testing

• Ability to design and implement endtoend automated API tests using Bruno Insomnia Postman or similar frameworks.
• Strong understanding of REST API behaviours request chaining environment variables authentication flows and test assertions.
• Experience testing APIs running on AWS API Gateway with Lambda backends including understanding of routing payload transformations throttling and logging.

AWS

• Handson experience with:
  • S3 (structured landing/prepared zones and artefact validation).
  • IAM (roles/permissions for automated testing and leastprivilege CI/CD).
  • Airflow/MWAA (endtoend workflow testing scheduled rebuilds and validation tasks).
  • Logging/monitoring (instrumentation for quality gates alerts and evidence capture).

Data & API Testing

• Data contract and schema validation; automated data quality checks (null/range volume deltas distribution/consistency) for identity datasets.
• Performance testing for query latency and batchprocess windows; regression testing for rebuilds and deployments.
• Compliance validation (consent enforcement PII risk auditready outputs) integrated into automated pipelines.

Qualifications :

• 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. consentonly processing at node/edge level versioncontrolled thresholds).
• Prior testing experience with identity resolution / data science / probabilistic systemsincluding 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.

NicetoHave Experience:

• Datadriven SaaS platforms; regulated data processing environments
• Contracttesting frameworks (e.g. Pact) and propertybased testing approaches
• Cloud observability stacks (e.g. CloudWatch/OpenSearch/Grafana) for pipeline and API SLOs
