Job Title: Lead Databricks Data Engineer
Location: Remote
Duration: 6 months+

Purpose:  

Build and operate the pipelines that land, conform and curate sources into the lakehouse. Each integration follows the same pattern — ingest to bronze, design, build silver, build gold — so this role adds throughput against a queue of integrations that is currently the binding constraint on coverage.  

Key responsibilities:  

• Build ingestion into the bronze layer for assigned sources: gateway and observability logs, productivity tool admin APIs, AI-enabled SaaS usage, hyperscaler billing exports and reference data. Land raw and untransformed, on a scheduled refresh, replayable if the downstream design changes.  
• Work to the shared bronze landing contract so each tool is ingested once and serves both this program and the parallel productivity initiative, rather than being integrated twice.  
• Build the silver layer: typed, deduplicated and conformed to the canonical dimensions, refreshed independently of any downstream publication schedule.  
• Build gold marts carrying attribution method, attribution level, cost basis and provisional status alongside cost and usage.  
• Implement the attribution and allocation logic designed by the analysts, including precedence resolution and ratio-based splitting of shared endpoint cost.  
• Work within Unity Catalog governance — shared bronze and silver, separate gold marts with a recorded owner per dataset — including permissions, lineage and cataloging.  
• Implement data quality rules and monitoring: completeness, freshness and tag-coverage checks with alerting, so pipeline problems surface before they reach a divisional invoice.  
• Manage the volume impact of enabling caller-identity data in the cost and usage report, which multiplies row counts by the number of calling identities per model.  
• Work to the per-source cadence — daily where controls and anomaly detection depend on it, monthly where they do not — within the team's existing CI/CD and promotion practices.  

Essential skills and experience:

• Advanced Databricks engineering: Delta Lake, medallion architecture, Databricks Workflows, Auto Loader and incremental ingestion patterns.  
• Unity Catalog to a governance standard — catalogs, schemas, permissions, lineage — not merely as a place tables happen to live.  
• Strong Python and PySpark, and strong SQL. Notebook-based development.  
• Ingestion from REST APIs including pagination, throttling, incremental watermarks and credential handling, plus cloud object storage across AWS, Azure and GCP.  
• Performance and cost optimization of Spark workloads: partitioning, clustering, file sizing and cluster configuration.  
• CI/CD for Databricks — asset bundles or equivalent — and Git-based development workflow.  
• Able to work to an existing catalog structure and coding standard rather than introducing a parallel approach.  

Desirable:  

• Databricks Genie familiarity, including preparing semantic context so natural-language querying returns trustworthy answers.  
• Experience with cloud billing data at volume.  
• Prior work on a shared platform where another team owned adjacent datasets in the same catalog.
