AI Summary

The Lead Ontologist will translate business use cases into semantic models, schemas, and query patterns to support knowledge-first systems. They will also communicate technical results to stakeholders and lead design workshops for client interactions.

Overview

Black Canyon Consulting (BCC) is searching for a Lead Ontologist supporting the delivery of knowledge-first systems. We turn fragmented scientific and enterprise data into structured, reusable knowledge assets. These systems are designed to support explainable reasoning, governed analytics, and trustworthy AI. The approach starts with the questions that matter and builds toward the semantics required to address them. We define competency questions as the contract for what a system must be able to answer, design queries that satisfy those questions, and derive schema and data transformations from there. The result is modular, minimal, and grounded systems that can be explained, validated, and extended over time.

BCC is seeking a Lead Ontologist to execute and help shape this approach. This role sits at the boundary between business understanding and technical implementation. You will work with stakeholders to clarify use cases, define competency questions, and translate those into semantic models, schemas, and query patterns. You will design and build models using LinkML and RDF/OWL, define query skeletons, and ensure that data transformation aligns with the intent of the question. You will also play a visible role in communicating results, both internally and with clients, explaining what the system can answer and why.

This is a remote-first role, with a preference for U.S.-based candidates working East Coast hours. Travel is limited, generally no more than once per month, and focused on design workshops or key client interactions. Depending on experience, you may lead these sessions directly or work alongside senior team members..
