Sr AI Data Engineer (Snowflake, AWS, GenAI)

Hyatt’s Data Engineering team is looking for a Senior AI Data Engineer to deliver data and AI capabilities for key initiatives. You’ll work with Data Product Management and Data Science to build scalable ingestion, transformation, and GenAI-enabled pipelines in Snowflake and AWS. A large part of the work is turning messy free-text customer data into clean, structured, trustworthy data with Snowflake Cortex AI, and packaging it as a Snowflake Native App. Roles and Responsibilities: Must have: Human-in-the-loop workflows and taxonomy-driven classification Data privacy and compliance for customer data Snowflake governance and security (RBAC, masking and row access policies, tagging) Automated regression testing for prompts and LLM outputs Snowpark Container Services or containerized ML/AI services Windows task automation and scripting AWS or Snowflake certifications Snowflake Cortex AI, Hyatt’s Data Engineering team is looking for a Senior AI Data Engineer to deliver data and AI capabilities for key initiatives.

A large part of the work is turning messy free-text customer data into clean, structured, trustworthy data with Snowflake Cortex AI, and packaging it as a Snowflake Native App. What you’ll do Ingest: Design and build pipelines from multiple source systems into Snowflake using AWS services and Python. Transform: Build and optimize SQL pipelines that cleanse, normalize, and deduplicate free-form text. Apply GenAI: Implement Snowflake Cortex AI workflows for classification, extraction, and structured data generation. Build prompt versioning, response parsing, validation, and fallback logic. Ship Native Apps: Build and deploy Snowflake Native Apps, including permissions, versioning, upgrades, and release workflows, with Snowpark logic and CI/CD for repeatable delivery. Measure quality: Define and track data and model KPIs (precision, recall, coverage, drift, error rates). Integrate Arize or a comparable platform for observability and root-cause analysis. Operationalize: Own production rollout, deployment automation, runbooks, documentation, and handoff to internal teams.
