Job Description: Senior Data Engineer (Snowflake, DBT, Fivetran)
Hybrid in Dallas
Role Overview
We are seeking a Senior Data Engineer who is highly hands-on and experienced in building 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 brings deep, practical experience in dbt coding and Snowflake engineering, along with a strong sense of ownership, accountability, and the ability to operate independently. Fivetran experience is beneficial, but the primary focus is on dbtand Snowflake expertise.
Key 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
- Deep understanding of virtual warehouses, micro-partitions, clustering, and query pruning
- Role-based access control (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 dbtdeployments.
- 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.
