• Governance: Experience with data versioning, schema evolution, and distributed metadata management.

Education and work experience

• Experience: 7+ years of professional experience in data engineering or data management, preferably within a high‑growth or multi‑brand industry.
• Education: Advanced degree (Masters or PhD) in Computer Science, STEM, or a related quantitative field.
