• Working knowledge of privacy and compliance practices (GDPR/CCPA) in data workflows.
• CI/CD, containers, test strategy; observability (metrics/logs/tracing) with tools like Datadog; incident readiness and SLO thinking.
• Demonstrated, recent hands-on use of AI-assisted development tools (e.g., GitHub Copilot, Cursor, OpenAI-based assistants).
• Clear technical writing; stakeholder management; ability to drive consensus and unblock execution.

• Direct experience with UID2/TTD integrations, Roku/Pubmatic/NBCU, or Meta Advanced Analytics/Google ADH pipelines.
