The Sr Data Engineer is a senior-level, hands‑on technical leader responsible for designing, building, and evolving Subway’s enterprise data platform on Snowflake or Databricks. This role serves as a technical authority and builder, driving Lakehouse architecture, engineering frameworks, and best practices across multiple data domains. The Sr Data Engineer operates with a high degree of autonomy, leading through working code and influence — shipping reference implementations, POCs, and platform‑level solutions that other teams build upon.

• Personally design and build reference implementations and production‑grade frameworks on Databricks or Snowflake.
• Design lakehouse platforms using Delta Lake or Iceberg Tables with Medallion (Bronze/Silver/Gold) architecture.
• Define and evolve enterprise data standards, patterns, and reusable accelerators.
• Ensure solutions align with data governance, security, scalability, and cost‑efficiency standards.
• Evaluate technologies through hands‑on benchmarking — not vendor decks.
• Build the first working version of complex pipelines, frameworks, and POCs (ingestion, CDC, streaming, DQ, observability, CI/CD).
• Drive emerging tech (Iceberg, Lakeflow , Openflow , Cortex, Mosaic AI) from POC to production rollout.
• Solve high‑complexity performance, cost, and governance challenges at petabyte scale.
• Identify and address systemic technical debt and architectural risks.
• Implement Lambda or Kappa architectures using Databricks Structured Streaming / DLT or Snowflake Dynamic Tables / Snowpipe Streaming.
• Build GenAI and ML enablement patterns (RAG, feature stores, semantic layers) using Databricks Mosaic AI or Snowflake Cortex.
• Partner with Data Science and Analytics teams to operationalize models and AI workflows.
• Collaborate closely with Product, Architecture, Security, Infrastructure, and Analytics leaders.
• Translate business needs into sound technical direction backed by working prototypes.
• Communicate technical trade‑offs, risks, and decisions clearly to technical and non‑technical stakeholders.
• Influence roadmaps and platform investments through technical insight and de‑risking POCs.
• Mentor Senior and Staff Data Engineers through pair‑programming, PR reviews, and design coaching.
• Raise engineering maturity by shipping working examples and codifying patterns.
• Foster a culture of technical excellence, learning, and continuous improvement.

• Exceptional hands‑on expertise in Databricks or Snowflake lakehouse platforms.
• Deep proficiency in PySpark or advanced SQL, plus Python for data engineering and automation.
• Proven experience building Medallion architecture with Delta Lake or Iceberg Tables.
• Real‑time and batch streaming experience (Lambda or Kappa) using Databricks DLT or Snowflake Dynamic Tables / Snowpipe Streaming.
• Hands‑on with orchestration tools — Airflow, Databricks Lakeflow, or Snowflake Openflow; dbt experience a plus.
• Performance and cost tuning expertise (clustering, partit ioning, Z‑ordering, warehouse/cluster sizing, Fin Ops).
• Governance experience with Unity Catalog (Databricks) or Horizon Catalog…
