• Make quality a standard, not an afterthought: Own the testing strategy, from unit tests built into the pipeline to independent regression testing and set shared quality standards with Core Data and data governance.
• Drive AI-powered data engineering: Use AI to speed up how the squads build, test, and operate data pipelines, and apply agentic AI to automate repetitive engineering work, with sound guardrails and human review.
• Turn business needs into a roadmap: Partner with product owners and tech leads to translating what the business needs into a clear, prioritized data roadmap.
• Raise the engineering bar: Mentor engineers, lead code reviews, and model the practices you want the squads to follow.
