Role Overview

Design, optimize, and operate reliable, large-scale, cost-aware Spark and Delta Lake workloads.

Build and optimize Spark pipelines on Microsoft Fabric or Databricks. Diagnose performance using Spark UI and Delta statistics. Manage Delta Lake design, Fabric capacity consumption, compute sizing, throttling exposure, and operational reliability. Create reusable Python libraries and Spark modules for ingestion, governance, security, monitoring, and optimization.

·       Shuffle skew, spill, OOM, task-duration analysis, AQE, join strategy, and predicate pushdown

·       Delta Lake optimization: liquid clustering, partitioning, Z-order, file sizing, OPTIMIZE, statistics, VACUUM, and incremental MERGE

·       Fabric capacity economics: CU-seconds, bursting, smoothing, throttling stages, pool configuration, node sizing, concurrency, and workload isolation

·       Production Python library development, packaging, validation, logging, testing, versioning, and documentation

·       Operational pipeline design: idempotency, watermarks, quarantine, monitoring, failure recovery, and SLA awareness

Good-To-Have Skills

·       OneLake security and access roles

·       Governance metadata and TBLPROPERTIES

·       Reusable ingestion and maintenance frameworks
