Role
Design and own a governed semantic layer and procedural query system that enables AI agents to reliably converse with enterprise data. Build the bridge between user intent → structured queries → reproducible results, ensuring all interactions are accurate, explainable, and deterministic.
Responsibilities
- Define canonical entities, relationships, metrics, and hierarchies
- Enforce consistent business definitions across systems
- Model join paths, grain, and aggregation rules
- Create versioned, reusable metric definitions
- Resolve conflicting logic across teams
- Ensure correctness across all query combinations
- Design APIs for filtering, aggregation, grouping, and joins
- Enable agents to operate via predefined semantic procedures, not raw SQL
- Map intent → validated query plans
- Support systems where users ask questions in natural language
- Ensure responses are grounded in: Semantic layer definitions Deterministic execution paths
- Control how queries are constructed: Enforce valid joins and filters Prevent ambiguity and incorrect aggregations
- Inspect and optimize generated SQL
- Maintain traceability from source → semantic model → output
- Implement validation tests and metric checks
- Optimize queries, materializations, and caching
- Ensure low-latency responses for interactive use
Requirements
- 5–7 years of experience in large-scale enterprise data modeling for AI/ML applications
- Strong proficiency in Java or Python, with a preference for Java for production service development and Python for NLP workflows
- Deep understanding of joins, grain, aggregations, and window functions
- Strong experience with semantic layers (e.g. Cube) and modern data warehouses (e.g. Snowflake)
- Experience building metric layers used across teams, and with query abstraction or API-based data access
Preferred
- Experience enabling natural language → data query systems Familiarity with:
- Controlled use of LLMs in data applications
- Query planning or rule-based systems
What We Are Not Looking For
- Direct AI/LLM access to raw databases
- Ad-hoc or conflicting metric definitions
- Opaque or non-traceable query generation
PHYSICAL DEMANDS AND WORKING CONDITIONS:
- Some travel is required, typically to meet with customers, team and organizational meetings, etc.
- Must be able to work exceptionally well with people of varying backgrounds and personality types.
- Ability to operate a computer and work at a desk for extended periods of time.
