A Day in the Life of Semantic Modeler – Data & AI!
- Architect and own the Universal Semantic Layer, ensuring it serves as the single source of truth for all reports, self-service, and AI/ML initiatives.
- Enable AI Agency: Build the metadata "map" that allows AI Agents and LLMs to understand, browse, and analyse enterprise data with high precision and trust.
- Democratize Data Access: Design a self-service environment where non-technical business users can explore data using business terms rather than complex SQL.
- Ensure Cross-Project Consistency: Align the semantic definitions used in traditional BI reporting with the features used in AI/ML model training to prevent "metric drift"
- Standardize Semantic Governance: Define the workflows for how new metrics are proposed, validated, and deployed into the enterprise semantic layer.
In this role, You will..
Be responsible for the following:
- Leading the design and evolution of the enterprise semantic layer, ensuring it is optimized for high-performance querying in BigQuery and seamless integration with downstream tools.
- Creating "Agent-Friendly" Metadata: Developing rich descriptions, tags, and relationship mappings within the semantic layer to guide AI Agents in autonomous data retrieval.
- Collaborating with Data Scientists and ML Engineers to ensure the semantic layer provides consistent, governed inputs for feature engineering and model inference.
- Developing and maintaining a "Metric Store" approach, allowing the business to define a KPI once and consume it everywhere (Dashboards, Python notebooks, AI Agents).
- Providing architectural guidance to BI and Delivery teams on how to build thin-client reports that rely entirely on the governed semantic model.
- Architecting the security and privacy layer within the semantic model, ensuring that PII and sensitive data are handled according to global compliance standards.
- Evaluating and implementing emerging "Headless BI" technologies to decouple data logic from the visualization layer, increasing architectural flexibility.
- Mentoring Data Modeler and Analytics Engineers on the shift from "flat-table" reporting to "object-oriented" semantic modeling.
- Leading the "Semantic Governance Board" to resolve naming conflicts and ensure that the bus.
What are we looking for?
- 10+ years of experience in Data Architecture, Software Engineering, or Information Management, with a specialized focus on building scalable semantic layers and metric stores.
- Extensive experience with Semantic Layer Technologies: Proficiency in tools like Looker (LookML)/dbt Semantic Layer/Cube/AtScale/Power BI (Tabular/DAX).
- Deep understanding of Data Modeling methodologies: Expert knowledge of Data Vault 2.0, Star Schema (Kimball), and Knowledge Graph/Ontology modeling.
- GCP Ecosystem Mastery: Proven experience architecting solutions on GCP, leveraging BigQuery, Dataform, Analytics Hub, and Dataplex.
- AI/Agent-Ready Modeling: Practical experience in structuring metadata for LLM consumption (RAG), ensuring that AI Agents can accurately navigate & query enterprise data without "hallucinating" business logic.
- Architectural Pattern Expertise: Understanding of Data Mesh and Data Fabric principles and how to implement “Headless BI" architecture.
- API & Integration Skills: Experience exposing semantic models via GraphQL, SQL, or REST APIs for consumption.
- Advanced Data Governance: Deep knowledge of metadata management, data lineage, and the ability to implement row-level and column-level security within the semantic layer.
- Excellent Communication: Ability to reconcile business definitions across departments and codify them into a single technical logic.
