• Partner directly with business teams to discover operational pain points and scope high-value AI solutions.
• Serve as BRUNT’s internal AI expert and first point of contact for employees who want to understand how AI tools can support their work, providing clear, accessible guidance that translates technical capability into practical business value.
• Deliver periodic practical training and enablement sessions to help BRUNT employees effectively use approved AI tools.

• Proven track record designing and implementing Retrieval Augmented Generation (RAG) architecture, vector data stores, embedding pipelines, and agent frameworks.
• Strong Python skills for backend services and API design (REST/GraphQL) paired with frontend capability (React, Next.js, or equivalent) to build internal tools end-to-end.
• Practical experience with Google BigQuery, specifically designing AI-consumable data access patterns, semantic layers, and grounding strategies.
