Full Job Description

BasisPath is seeking an experienced Semantic Knowledge Graph Engineer to design, develop, and maintain advanced semantic and graph-based applications that support mission-critical analysis and decision-making across the U.S. Intelligence Community (IC). The ideal candidate combines deep expertise in RDF graph technologies with practical software engineering skills and a strong understanding of ontological modeling frameworks such as the Common Core Ontologies (CCO) and Basic Formal Ontology (BFO).

About BasisPath:

BasisPath, a rapidly growing woman and veteran-owned small business, is actively seeking talented candidates to support our expanding business commitments. We offer a comprehensive benefits package, including signing bonuses, relocation assistance, expense reimbursement, 100% paid health insurance, competitive compensation, growth opportunities, profit sharing, relevant training, and generous PTO.

At BasisPath, we prioritize our employees' well-being and professional development. Join us and become part of our dedicated team!

Responsibilities:

Design, develop, and maintain advanced semantic and graph-based applications that support mission-critical analysis and decision-making across the U.S. Intelligence Community (IC).
Develop and manage RDF-based databases and graph solutions using technologies such as AllegroGraph, Amazon Neptune, or comparable platforms.
Build scalable microservices and RESTful APIs that expose graph data and analytics capabilities to downstream systems.
Implement complex graph algorithms for relationship analysis, pattern detection, and data reasoning.
Design and extend ontological frameworks aligned with the Common Core Ontologies (CCO), Basic Formal Ontology (BFO), and IC data standards.
Collaborate with analysts, data scientists, and mission stakeholders to translate operational requirements into semantic architectures and optimized solutions.
Optimize graph queries and data structures for performance in secure, resource-constrained, and classified computing environments.
Contribute to Agile development practices, including sprint planning, code reviews, automated testing, and CI/CD workflows.
Ensure compliance with IC/DoD cybersecurity and data protection standards.

Required Qualifications:

U.S. Citizenship and an active Top Secret clearance with the ability to obtain and maintain SCI.
Bachelor’s degree in Computer Science, Engineering, Physics, Mathematics, or a related technical discipline.
Minimum of five years of professional software engineering experience.
Hands-on experience with RDF and graph databases (e.g., AllegroGraph, Amazon Neptune, GraphDB, etc.).
Proficiency in Python, Java, or C++, with experience developing microservices and RESTful APIs.
Proficiency in graph query languages such as SPARQL, Cypher, or Gremlin.
Strong understanding of semantic web standards (RDF, OWL, SHACL).
Experience deploying and maintaining applications in classified or air-gapped environments.

Desired Qualifications:

Experience supporting Intelligence Community missions or working within classified domains.
Direct experience implementing or extending CCO or BFO.
Experience with Docker or Kubernetes deployments in secure environments.
Familiarity with graph visualization tools, semantic analytics, and reasoning systems.
Experience with AWS or Azure, especially graph and analytics services.
Relevant certifications such as Security+, CISSP, or other DoD 8570 credentials.
Advanced degree in Computer Science, Data Science, or a related field.
Current TS/SCI with Polygraph preferred.

If you are passionate about semantic technologies, ontological modeling, and developing solutions that enhance data interoperability and reasoning across national security missions, we would love to hear from you.
