Position Overview

Pantheon Data has a SME Graph/Data Engineer requirement to support development and deployment of our CB Suite product. This roll reports to the Principal Cloud & ML Ops Engineer, and will support CB Suite product development.

The SME Graph Database Engineer will build and lead our semantic infrastructure capability for knowledge domain applications. We seek a technical leader who can establish graph-based architecture as a core competency, grow a team around it, and champion the graph approach across the organization. You will own the integration of open-source graph database infrastructure into our growing platform, serving as the semantic backbone for cross-domain knowledge management.

More importantly, you will shape how Pantheon thinks about and implements knowledge graphs, establishing standards, mentoring engineers, and building the foundation for scalable semantic systems.

• Own query performance optimization strategies: rewriting, caching, materialized views, indexing.
• Design and implement ontology versioning and migration frameworks.
• Manage security architecture: access control, audit logging, sensitive data handling.
• Support domain onboarding as new frameworks are added to the graph.

• 10+ years  experience with graph database development and deployment for large-scale enterprise data projects including GSQL, entity-relationship mapping, schema development, temporal data management, ontology design, hybrid graph/relational data systems, and query automation.
• Familiarity with cloud platforms (e.g., AWS, Azure, GCP).
• Demonstrated experience leading technical teams or building engineering capabilities.
• Track record of production deployments with graph databases at scale.
• Experience mentoring engineers and influencing architectural decisions.
• Ability to use Jira, Confluence, and SharePoint folder access for configuration and data management processes.
• Competency in Microsoft applications including Word, Excel, Visio and PowerPoint.
