Senior Databricks Data Engineer

Position Overview

We are looking for a Senior, Super Hands-On Databricks Data Engineer who lives and breathes code, query optimization, and modern data architecture. In this role, you won't just design architectures on whiteboards—you will write production PySpark/SQL, optimize Databricks clusters, build streaming and batch pipelines, and enforce data governance.

You will own end-to-end pipeline execution from raw ingestion to curated Gold layer models, playing a lead role in modernizing our Lakehouse platform.

Key Responsibilities

1. Hands-On Pipeline Development & Lakehouse Architecture

• Design, build, and maintain enterprise-scale batch and real-time streaming pipelines using PySpark, SQL, Delta Live Tables (DLT), and Auto Loader.
  
• Implement and refine Medallion Architecture (Bronze Silver Gold) to support downstream BI, reporting, and Machine Learning workloads.
  
• Enforce schema evolution, ACID transactions, and data compaction using Delta Lake core constructs.
  

2. Performance Tuning & Optimization (Deep Tech)

• Diagnose and resolve Spark performance bottlenecks: data skew, OOM errors, excessive shufflings, and memory spills.
  
• Optimize queries using Liquid Clustering, Z-Ordering, Data Partitioning, AQE (Adaptive Query Execution), and Photon engine tuning.
  
• Benchmark and optimize Databricks compute workloads to minimize DBU (Databricks Unit) consumption and cloud costs (FinOps).
  

3. Governance, Security & Quality

• Implement end-to-end data governance, fine-grained access control (row/column-level security), and lineage tracking using Unity Catalog.
  
• Automate automated data quality validation checks and alert mechanisms across the pipeline life cycle.
  

4. Operations, CI/CD & DevOps

• Automate pipeline orchestration using Databricks Asset Bundles (DABs) or Databricks Workflows / Apache Airflow.
  
• Build CI/CD pipelines (GitHub Actions, Azure DevOps, or GitLab) for automated testing, deployment, and code promotions.
  

Requirements

Required Skills & Qualifications

Must-Haves

• Experience: 8+ years in Data Engineering, with 4+ years of intensive, hands-on production experience on Databricks.
  
• Programming Mastery: Fluent in PySpark, Advanced SQL, and Python.
  
• Databricks Ecosystem: Deep experience with Delta Lake, Unity Catalog, Delta Live Tables (DLT), Auto Loader, and Databricks Workflows.
  
• Cloud Infrastructure: Strong hands-on experience in at least one primary cloud provider (AWS, Azure, or GCP) integration with Databricks (S3/ADLS Gen2, IAM, Key Vaults/Secret Manager).
  
• Data Modeling: Solid understanding of dimensional modeling (Kimball), One Big Table (OBT) strategies, and data vault patterns.
  
• CI/CD & Software Engineering: Proficient in Git workflows, unit testing PySpark code (pytest), and deployment automation.
  

Preferred / Nice-to-Haves

• Certifications: Databricks Certified Data Engineer Professional.
  
• Streaming: Hands-on with Apache Kafka, Event Hubs, or Kinesis integration via Structured Streaming.
  
• GenAI / ML Ops: Familiarity with MLflow, Feature Store, or Vector Search within Databricks.
  
• Infrastructure as Code (IaC): Experience using Terraform to provision Databricks workspaces and storage resources.
  

Performance Indicators (How success is measured)

1. Pipeline Reliability: Maintaining strict SLA thresholds on critical Gold-layer models.
   
2. Cost Efficiency: Measurable reduction in DBU costs through effective compute profiling and tuning.
   
3. Code Quality: High test coverage and zero-downtime CI/CD deployments.
