• Develop and optimize SQL-based transformation pipelines for cleansing, normalization, deduplication, and processing of free-form text.
• Build Generative AI workflows for classification, extraction, and structured data generation using Snowflake Cortex AI or comparable production LLM platforms.
• Develop prompt versioning, response parsing, validation, and fallback logic for production AI workflows.
• Build and deploy Snowflake Native Apps, including application packaging, permissions, versioning, upgrades, and release workflows.
• Integrate Snowpark-based logic and CI/CD processes to support repeatable application delivery.
• Define and track data and model quality KPIs, including precision, recall, coverage, drift, and error rates.
• Implement ML/LLM observability and monitoring using Arize or comparable platforms.
• Build structured extraction pipelines capable of processing free-text data at scale.
• Support production deployments, operational readiness, automation, documentation, runbooks, and handoff to internal teams.
• Partner with Data Science, Product, and technical stakeholders throughout design and delivery.

The ideal candidate brings a strong traditional Data Engineering foundation along with hands-on experience developing and deploying production Generative AI solutions. This is a hands-on engineering role requiring deep Snowflake expertise, strong AWS and Python skills, and experience taking AI/LLM workflows into production., * 8+ years of overall technology experience, including 5+ years of Data Engineering experience.
