SDET

As an SDET, you'll build the automated testing frameworks that ensure the quality, reliability, and integrity of our customer data ecosystem. You'll work across data, Martech, and engineering environments to test everything from customer data pipelines and identity resolution to SDK events, APIs, CDP integrations, and downstream activation in platforms such as Databricks, mParticle, Braze, and OneTrust. This is a hands-on engineering role focused on automating quality rather than manually testing it. You'll write code that tests code, build scalable validation frameworks, and work closely with Data Engineers and Martech teams to identify issues early, prevent regressions, and ensure customer data is accurate, compliant, and ready for activation. Please note this role is part time (Monday / Tuesday / Wednesday half day). What Will You Do? • Build automated testing frameworks to validate customer data, schemas, data contracts, and identity resolution across the data ecosystem • Develop automated tests for web and app events, SDK implementations, consent signals, and customer journeys • Test end-to-end data flows across platforms such as Databricks, mParticle, Braze, and OneTrust, including API integrations and audience activation • Validate batch and near real-time data pipelines, transformations, data quality, freshness, and latency against defined SLAs • Use SQL and Python to identify data anomalies, validate large datasets, and automate regression testing • Build API mocks and automated integration tests to ensure data and customer actions flow correctly between systems • Establish automated data quality and schema validation rules to detect corrupted records, data issues, and schema drift • Partner closely with Data Engineers and Martech teams to triage defects, identify root causes, and prevent recurring issues • Embed automated testing and data quality checks into CI/CD workflows and continuously improve the testing architecture • Validate consent and preference management across customer data flows to support GDPR, UK GDPR, and other privacy requirements.
