Senior Data Engineer

• Design, build, and optimize scalable data pipelines and ETL/ELT workflows to ingest, transform, and load data from multiple source systems into Snowflake.
• Develop, maintain, and enhance data transformation logic using DBT Cloud following best practices (modularity, testing, documentation, CI/CD).
• Build and manage integrations using SnapLogic or equivalent ETL/iPaaS tools (Informatica, Talend, Matillion, Fivetran, etc.) for batch and near real-time data movement.
• Write and optimize complex SQL queries, stored procedures, and Snowflake-specific features (streams, tasks, materialized views, clustering, warehouses sizing) for performance and cost efficiency.
• Knowledge on data models (dimensional/star schema, Data Vault, or 3NF) and contribute to building a semantic layer for consistent, governed reporting across BI tools.
• Collaborate with data analysts, BI developers, and business stakeholders to translate requirements into reliable, well-documented data solutions.
• Implement data quality checks, validation frameworks, and monitoring/alerting for pipeline reliability.
• Manage version control, CI/CD deployment pipelines for DBT models and ETL jobs (Git, GitHub Actions/Azure DevOps/Jenkins).
• Optimize Snowflake performance and cost through query tuning, warehouse right-sizing, and efficient storage/partitioning strategies.
• Document data flows, transformation logic, and semantic layer definitions for maintainability and knowledge transfer.
• Mentor junior data engineers and enforce engineering best practices and coding standards.
