Job requirements

Key Responsibilities

• Design, develop, and maintain ETL/ELT pipelines using PySpark and Python in Databricks (including notebooks, jobs, Delta Lake tables, and Unity Catalog for governance).

• Implement medallion architecture (bronze/silver/gold layers) and optimize Spark jobs for performance, cost, scalability, and reliability (handling partitioning, skew, caching, adaptive query execution, etc.).

• Write efficient SQL queries for data transformation, validation, and analytics within Databricks.

• Provision and manage cloud infrastructure using Terraform (IaC) for Databricks workspaces, clusters, jobs, storage (ADLS/S3), networking, IAM roles/permissions, and related resources on Azure and/or AWS.

• Implement and maintain CI/CD pipelines using Jenkins, GitHub (Actions/Repositories), and branching strategies for automated testing, deployment of notebooks, jobs, Delta Live Tables, and Terraform configurations.

• Integrate data from diverse sources (databases, APIs, streaming, files) into cloud storage and processing layers.

• Ensure data quality, lineage, security, and compliance (including Delta Lake ACID transactions, schema evolution, time travel, and access controls).

• Monitor pipeline performance, troubleshoot failures, and implement alerting/observability (using Databricks tools, cloud monitoring services, or third-party solutions).

• Optimize cloud costs through auto-scaling clusters, spot instances, job scheduling, and efficient resource usage.

• Collaborate in agile teams, participate in code reviews, and contribute to best practices for data engineering.

Required Skills & Experience

• Strong proficiency in Python and PySpark for distributed data processing and ETL.

• Advanced SQL skills with experience in complex querying, window functions, and optimization.

• Hands-on experience with Databricks (clusters, notebooks, Delta Lake, Unity Catalog, Delta Live Tables, workflows/jobs).

• Proficiency in Terraform for infrastructure provisioning and management (Databricks resources, cloud storage, IAM, networking).

• Experience with GitHub for version control and collaboration (branching, pull requests, code reviews).

• Solid knowledge of CI/CD practices and tools, particularly Jenkins (pipelines, plugins for Databricks/GitHub/Terraform).

• Working experience on Azure (Data Lake, Data Factory, Synapse, Key Vault, etc.) and/or AWS (S3, Glue, EMR, IAM, Lambda, etc.).

• Understanding of big data concepts, data modeling (star/snowflake, dimensional), and lakehouse principles.

• Familiarity with performance tuning in Spark/Databricks environments.
