Snowflake DBT Developer

Overview Senior Data Engineer (Snowflake, DBT, Fivetran) — Hybrid in Dallas. We are seeking a hands‑on data engineering expert who builds modern, scalable data pipelines and transformation frameworks using Snowflake and dbt. This role focuses on delivering high‑quality, production‑grade data solutions with strong engineering discipline, leveraging Python, CI/CD, and Git‑based development practices. The ideal candidate has deep, practical experience in dbt coding and Snowflake engineering, a strong sense of ownership and accountability, and the ability to operate independently. Fivetran experience is beneficial, but the primary focus is on dbt and Snowflake expertise. Responsibilities Design, build, and maintain scalable ELT pipelines, leveraging Fivetran (or similar tools) for ingestion and dbt for transformation. Develop and maintain robust dbt projects, including: Modular models (staging, intermediate, marts) Reusable macros and Jinja templating Snapshots for SCD Type 2 handling Schema and custom data quality tests Documentation using dbt docs Implement modular and reusable dbt architecture supporting multi‑environment deployments (dev, test, prod). Design and implement scalable data models using best practices (dimensional modeling, star schema, and data vault where applicable). Optimize Snowflake performance and cost efficiency, including: Query tuning and execution optimization Warehouse sizing and workload management Effective use of micro‑partitions, clustering, and pruning Build and enforce strong data quality and validation frameworks, including: Unit testing for transformations (dbt and custom frameworks) Data reconciliation and consistency checks Develop Python‑based solutions for automation, orchestration support, metadata‑driven processing, and operational tooling. Implement and enforce Git‑based development practices: Version control, branching strategies, pull requests, and code reviews Consistent and collaborative engineering workflows Build, maintain, and enhance CI/CD pipelines for dbt deployments: Automated build, test, and deployment processes Environment promotion (dev → test → prod) Integration with enterprise deployment pipelines Work with orchestration tools such as Airflow / Astronomer to schedule, monitor, and manage data pipeline execution (preferred). Collaborate closely with platform, governance, and business teams to align on data requirements, access control, and delivery expectations. Required Qualifications 10+ years of experience in data engineering / analytics engineering roles. Strong hands‑on experience with dbt in production, including: Model development and dependency management Macro development and reusable frameworks Testing strategies (schema tests, custom tests) Deployment and environment management Strong Snowflake expertise, including: Data modeling and warehouse design Performance tuning and cost optimization Virtual warehouses, micro‑partitions, clustering, and query pruning RBAC and secure data access Advanced SQL expertise with ability to build and optimize complex transformations. Strong Python programming skills for data engineering use cases. Proven experience with Git integration, including collaborative development workflows. Strong experience implementing CI/CD pipelines for data platforms and dbt deployments. Experience building and maintaining production‑grade data pipelines with SLAs, monitoring, and reliability standards. Preferred Qualifications Experience with Fivetran (connector setup, ingestion patterns, schema management, troubleshooting). Experience with Airflow / Astronomer or similar orchestration tools. Exposure to data governance, lineage, and observability tools. Financial services / banking domain experience is strongly preferred and will be prioritized, though not mandatory. #J-18808-Ljbffr Cognizant
