  • Evaluate and recommend appropriate data storage patterns (relational, dimensional, lakehouse, graph).


Data Integration:

  • Architect and oversee data pipelines and ETL/ELT processes across source systems.
  • Design integration patterns for batch, near-real-time, and streaming data flows.
  • Ensure robust data lineage, traceability, and auditability across all pipelines.

Analytics Enablement:

  • Develop semantic and analytical data models that serve BI, reporting, and advanced analytics use cases.
  • Partner with analytics and data science teams to define trusted data products.
  • Champion a self-service data culture by enabling reusable, well-documented data assets.

  • Proven ability to translate business requirements into scalable data architecture solutions.


Preferred:

  • Prior exposure to conversational AI platforms or event-driven architectures.
