Skills
About the Role
You will design, build, and optimize data pipelines and ETL workflows in Snowflake using Snowpark, Streams/Tasks, and Snowpipe. You will develop scalable data models supporting user 360 views, churn prediction, and recommendation engine inputs, and lead integration across data sources including MySQL, BigQuery, Redis, Kafka, GCP Storage, and API Gateway. You'll implement CI/CD for data pipelines using Git and dbt, and define data quality checks and auditing pipelines. You will mentor and guide junior data engineers, partner with Data Science, ML, and Backend teams to productionize machine learning features, and collaborate with Legal, Security, and Infrastructure teams on compliance and governance of user data. You will tune algorithm performance, establish data partitioning, clustering, and materialized views, and build dashboards to monitor pipeline health. You'll also establish naming conventions, data lineage, and metadata standards, lead code reviews, and contribute to the company's evolving data mesh and streaming architecture vision.
