Job Description

To develop, implement, and optimize complex Data Warehouse (DWH) and Data Lakehouse solutions using the Databricks platform (including Delta Lake, Unity Catalog, and Spark) to ensure a scalable,
- performance, and governed data foundation for analytics, reporting, and Machine Learning.

Responsibilities

A. Databricks Development and Architecture

• Advanced Design and Implementation: Design and implement robust, scalable, and
  - performance ETL/ELT data pipelines using Py
  Spark/Scala and Databricks SQL on the Databricks platform.
• Delta Lake: Expertise in implementing and optimizing the Medallion architecture (Bronze, Silver, Gold) using Delta Lake to ensure data quality, consistency, and historical tracking.
• Lakehouse Platform: Efficient implementation of the Lakehouse architecture on Databricks, combining best practices from DWH and Data Lake.
• Performance Optimization: Optimize Databricks clusters, Spark operations, and Delta tables (e. g. , Z-ordering, Compaction, Tuning Queries) to reduce latency and computational costs.
• Streaming: Design and implement
  - time/near-real-time data processing solutions using Spark Structured Streaming and Delta Live Tables (DLT).

B. Governance and Security

• Unity Catalog: Implement and manage Unity Catalog for centralized data governance,
  - grained security (row/column-level security), and data lineage.
• Data Quality: Define and implement data quality standards and rules (e. g. , using DLT or Great Expectations) to maintain data integrity.

C. Operations and Collaboration

• Orchestration: Develop and manage complex workflows using Databricks Workflows (Jobs) or external tools (e. g. , Azure Data Factory, Airflow) to automate pipelines.
• Dev
  Ops/CI/CD: Integrate Databricks pipelines into CI/CD processes using tools like Git, Databricks Repos, and Bundles.
• Collaboration: Work closely with Data Scientists, Analysts, and Architects to understand business requirements and deliver optimal technical solutions.
• Mentorship: Provide technical guidance and mentorship to junior developers and promote best practices.

A. Mandatory Knowledge (Expert Level)

• Databricks Platform: Proven,
  - level experience with the entire Databricks ecosystem (Workspace, Cluster Management, Notebooks, Databricks SQL).
• Apache Spark: In-depth knowledge of Spark architecture (RDD, Data
  Frames, Spark SQL) and advanced optimization techniques.
• Delta Lake: Expertise in implementing and managing Delta Lake (ACID properties, Time Travel, Merge, Optimize, Vacuum).
• Programming Languages: Advanced/expert-level proficiency in Python (with Py
  Spark) and/or Scala (with Spark).
• SQL: Advanced/expert-level skills in SQL and Data Modeling (Dimensional, 3NF, Data Vault).
• Cloud: Solid experience with a major Cloud platform (AWS, Azure, or GCP), especially with storage services (S3, ADLS Gen2, GCS) and networking.

B. Additional Knowledge (Major Advantage)

• Unity Catalog: Hands-on experience with implementing and managing Unity Catalog.
• Lakeflow: Experience with Delta Live Tables (DLT) and Databricks Workflows.
• ML/AI Concepts: Understanding of basic MLOps concepts and experience with MLflow to facilitate integration with Data Science teams.
• Dev
  Ops: Experience with Terraform or equivalent tools for Infrastructure as Code (Ia
  C).
• Certifications: Databricks certifications (e. g. , Databricks Certified Data Engineer Professional) are a significant advantage.

C. Education and Experience

• Education: Bachelor’s degree in Computer Science, Engineering, Mathematics, or a relevant technical field.
• Professional Experience: Minimum of 5+ years of experience in Data Engineering, with at least 3+ years of experience working with Databricks and Spark at scale.
