What this job asks for AI summary
This role centers on building and maintaining knowledge graphs and knowledge bases — designing pipelines that pull entities and relationships from raw data, linking them into structured graph databases, and validating the quality of the resulting information. The work spans backend engineering, ontology and schema design, and applied AI, with an expectation of mentoring junior colleagues and communicating findings to both technical and non-technical audiences. It suits engineers with hands-on graph database experience and a solid Java/Spring background who hold or can obtain a security clearance.

Why we read it this way (6)
This role sits at the intersection of backend software engineering and applied AI/knowledge graph work, making it a genuine hybrid between Software Developers (15-1252) and Data Scientists (15-2051). The primary day-to-day work — building pipelines, designing graph schemas, writing backend services in Java/Spring Boot — leans toward software development, so 15-1252 was chosen as primary.
Security clearance is listed as a hard gate: candidates must hold an active Secret (or higher) clearance, or be able to obtain one. The 'ability to obtain' language is included in the gate, so the clearance requirement is set to Secret.
The role requires candidates to maintain a primary residence within a two-hour drive of Herndon, VA for onsite collaboration; it is not fully remote.
The monitoring/observability skill appears twice in the Desired Skills section under slightly different groupings (Prometheus/Grafana/CloudWatch/ELK and OpenTelemetry/Splunk/Prometheus/Grafana/CloudWatch). These have been consolidated into a single preferred skill entry.
No overall years-of-experience requirement is stated in the posting. Seniority is assessed as Senior based on the scope of responsibilities: end-to-end ownership, technical decision-making, mentoring junior data scientists, and customer-facing communication.
Requires a Secret clearance — the cleared population is a small fraction of this occupation, so the real candidate pool is materially smaller than the estimate below, which does not model clearance.
