• Modern data platform paradigms-data lake, medallion architecture, data mesh concepts, and consumption layer design.
• Machine learning pipeline requirements-feature engineering, training data preparation, and model data dependencies.
• Data governance frameworks-metadata management, lineage, cataloging, access control, and regulatory compliance (HIPAA).
• Agile engineering practices-sprint delivery, DevOps hygiene, CI/CD for data pipelines, and technical documentation standards.

Skills:

• Cultural competency and the ability to communicate effectively in a culturally sensitive manner with both individuals and groups from diverse backgrounds.
• Architect and deliver complex, production-grade data pipelines that meet enterprise reliability and performance standards.
• Design scalable data models and platform structures that serve analytics, reporting, and AI consumption patterns simultaneously.
• Lead data quality engineering-automated testing, validation frameworks, SLA monitoring, and incident response.
• Mentor and elevate Data Engineers through code review, architectural feedback, and knowledge transfer.
• Translate product and analytical requirements into sound engineering designs and delivery plans.

Abilities:

• Communicate complex data concepts clearly to both technical and non-technical stakeholders.
• Work independently and manage competing priorities in a lean, fast-paced team environment.
• Embrace accountability and take ownership of deliverables end-to-end.
