Our target playground is the cutting edge of modern cloud data platforms, specifically Microsoft Fabric IQ on Azure (or equivalent stacks).

True to our culture of ownership and passion, you won't just draw diagrams; you will bridge the gap between complex enterprise data and Generative AI, shaping how intelligent systems search and understand information.

Design the LLM enrichment strategy (taxonomy, prompts, evaluation) using Azure OpenAI or equivalent LLM services

Produce the phased data roadmap for the Build phase

Align technical direction with client stakeholders

Required Qualifications:

Solid experience in data architecture, with deep knowledge of knowledge graphs, semantic layers, or ontologies.

Hands-on experience with modern cloud data platforms and services (e.g., Azure, AWS, GCP, Snowflake, Databricks)

Working knowledge of graph/knowledge-layer platforms such as Microsoft Fabric IQ, Palantir Foundry, Neo4j with ontology support, or dbt Semantic Layer

Proficient in knowledge graph/ontology modeling concepts (e.g., RDF/OWL, property graphs, semantic layers) and comfortable working across query languages such as GQL, Cypher, or SPARQL

Experience designing LLM-augmented pipelines with human-in-the-loop review

Strong client-facing communication and leadership skills

Hands-on experience with Microsoft Fabric / Fabric IQ specifically

Direct hands-on experience with RDF/OWL

CPG, retail, or food industry experience

Familiarity with schema.org, JSON-LD, and GEO (Generative Engine Optimization)

Microsoft certifications: Fabric Analytics Engineer or Azure Solutions Architect Expert
