Databricks Data Engineer

Job Role: Databricks Data Engineer
Job Location: Seattle, WA(Onsite)
Job Type: Long Term Contract
Pay Range: $50 to $60/Hr on W2

Must Have Technical/Functional Skills

• Successfully executed a data migration or modernization to Data Bricks, preferably IBM Data Stage to Data Bricks on AWS.
• Should have Experience in handling Large Migrations to Data Bricks.
• Should have good analytical skills to compare the legacy and modern data platform end to end right from source to target.
• Good understanding of DataBricks implementation of Medallion layer architecture.
• Independently Lead and Managed large Data Bricks migrations.
• CI/CD Integration: Implement version control (e.g., Git) and automated deployment processes for Databricks assets.

Technical and Architectural Skills
Core Data Engineering Languages

• Experience in Advanced SQL for building modular analytics workflows, utilizing advanced Common Table Expressions (CTEs), and writing high-performance queries inside Data Bricks SQL Analytics.
• Experience in Python or Scala to build, optimize, and debug complex data transformation scripts, custom functions, and machine learning pipelines.

Big Data & Architecture Core

• Experience in Apache Spark Ecosystem for understanding cluster execution flow, memory allocation, driver/worker nodes, and handling data frames.
• Experience in Delta Lake Architecture to understand ACID transactions on object storage, data skipping, partition strategies, and automated data compaction.

Databricks Platform Expertise

• Experience in Delta Live Tables (DLT) & Workflows for constructing and orchestrating production-ready, declarative streaming, and batch ETL pipelines.
• Experience in Unity Catalog for setting up data governance, column/row-level access control, and tracking end-to-end data lineage across workspaces.
• Experience in Auto Loader for implementing modern, incremental data ingestion patterns from cloud blob storage into the lakehouse.

Code Translation & Refactoring
Pipeline Conversion

• Translate visual DataStage Parallel Jobs and Sequences into Python/PySpark scripts or Data bricks Notebooks.

Legacy Refactoring

• Modernize legacy logic rather than applying "lift and shift" anti-patterns; adapt workflows to think in distributed DataFrames rather than DataStage stages.

Logic Mapping

• Map DataStage components-such as Aggregators, Joiners, Transformers, and Sort stages-to equivalent Spark operations.

Testing & Reconciliation
Validation & Reconciliation

• Build automated reconciliation frameworks to compare row counts, checksums, and aggregate sums between legacy DataStage outputs and new Databricks output.

Data Cleansing

• Identify and resolve data type discrepancies, null-handling differences, and encoding issues during the extraction and loading phases.

Platform Orchestration & Governance
Orchestration

• Replace DataStage sequence jobs with Databricks workflows (or external orchestrators like Azure Data Factory/Airflow) to schedule and manage dependencies.

Data Governance

• Enforce data lineage, security, and cataloging using Unity Catalog to ensure compliance in the new Lakehouse environment.

Cloud Infrastructure & CI/CD

• Cloud Providers (AWS): Understanding underlying cloud object storage, identity access management (IAM), and network security configurations.
• DevOps & Bundles: Familiarity with Databricks Asset Bundles (DABs) and CI/CD tools to automate the deployment of workspaces and pipeline assets.

Legacy Assessment & Migration Mechanics
Code Conversion & Translation

• The ability to parse legacy code structures and refactor them into Databricks-native code.

AI-Assisted Migration

• Skills in using AI coding assistants and open framework agent tools to analyze application interdependencies, automate schema mapping, and accelerate lift-and-shift workloads.

Code Conversion & Translation

• The ability to parse legacy code structures from ETL pipelines, Informatica, data Stage preferred.
• Experience working in Agile teams and understanding of data governance frameworks.

Responsibilities
Post-Migration Support

• Support post-migration environment from IBM DataStage to Databricks.

Incident & Lifecycle Management
CI/CD Deployment

• Support code deployments across Development, Test, and Production environments using Databricks Repos and REST APIs.

Monitoring & Alerting

• Set up monitoring via Databricks System Tables and observability tools to catch job failures, data anomalies, or latency spikes early.

Pipeline Maintenance & Orchestration
Workflow Management

• Transition from DataStage job sequences to native data bricks workflows for scheduling, dependency tracking, and alerts.

ETL Refactoring

• Troubleshoot and fix issues in generated PySpark or Spark SQL code that replaced legacy DataStage Transformer or Lookup stages.

Streaming & Batch Integration

• Support ongoing data ingestion using data bricks autoloader to process files continuously from cloud storage.

Performance Tuning & Cost Optimization
Compute Management

• Monitor and configure serverless or classic clusters to prevent over-provisioning.

Query Optimization

• Analyze Spark execution plans. Replace inefficient row-by-row processing logic (a common DataStage carryover) with vectorized operations and native Spark functions.

Storage Optimization

• Maintain Delta Lake tables by enforcing layout optimization ((ZORDER).

Data Governance & Security
Access Control

• Implement granular permissions, column-masking, and row-level filters using Data bricks unity catalog to replace DataStage's legacy security policies.

Data Quality

• Utilize Delta Live Tables (DLT) to build pipelines with built-in, declarative data quality expectations and monitoring.

Additional Skills

• Excellent communication Skills.
• Ability to collaborate with Legacy and Modernize application teams and stakeholders.
