About The Position

Platinum Technologies is seeking a Senior Software Engineer to join our team. In this position you will design, develop, integrate, and maintain software applications and services that support Object-Based Intelligence (OBI) mission requirements, enterprise ontologies, and knowledge graph capabilities. The Senior Software Engineer serves as a key contributor to the design, development, and sustainment of mission-critical software solutions that enable semantic data integration, knowledge management, and advanced analytics. This position develops scalable applications, APIs, and microservices that integrate ontology-driven data models, knowledge graphs, and enterprise data sources to support Object-Based Intelligence workflows. Working within an Agile DevSecOps environment, the Software Engineer collaborates with ontology engineers, database engineers, data scientists, and Government stakeholders to deliver secure, high-performance applications that leverage Semantic Web technologies and AI/ML capabilities.

Requirements

• Must be a U.S. citizen and have an active TS/SCI with CI polygraph.
• Minimum twelve (12) years of experience and an advanced degree or 17 years of experience with a bachelor's degree.
• Demonstrated experience designing, developing, and maintaining enterprise software applications using modern programming languages such as Java, Python, or C#.
• Experience developing RESTful APIs, microservices, and distributed applications.
• Experience integrating applications with relational databases, graph databases, or semantic data platforms.
• Experience with containerization technologies such as Docker and Kubernetes/OpenShift.
• Familiarity with Agile software development methodologies, DevSecOps practices, and CI/CD pipelines.
• Experience with version control systems such as Git.
• Ability to communicate complex technical concepts effectively to both technical and non-technical stakeholders.

• Implement software solutions that leverage Semantic Web technologies, including RDF, OWL, SPARQL, and graph-based data models, to enable advanced search, reasoning, and data interoperability.
• Collaborate with ontology engineers, database engineers, data scientists, analysts, and Government stakeholders to translate mission requirements into scalable software solutions.
• Design and develop secure, containerized applications using modern software engineering practices and cloud-native technologies.
• Integrate heterogeneous data sources through RESTful APIs, messaging services, and data integration frameworks to support enterprise knowledge management.
• Develop automated unit, integration, and system tests while supporting continuous integration and continuous deployment (CI/CD) pipelines.
• Optimize application performance, scalability, and reliability to support high-volume mission operations and advanced analytics.
• Participate in Agile development activities, including sprint planning, code reviews, technical design sessions, and backlog refinement.
• Produce and maintain software design documentation, interface specifications, API documentation, and technical implementation guides.
• Support AI/ML initiatives by developing software services that enable access to semantic data, knowledge graphs, and contextual reasoning capabilities.
• Provide technical leadership, mentoring, and knowledge transfer activities to Government personnel and project team members on software engineering best practices.
