Job description

Who we are.
Platinum Technologies is a Northern Virginia based integrated solutions firm that specializes in Cybersecurity, Cloud and Digital Services to the Public Sector. Our team solves hard problems and helps our Mission Partners achieve their goals. If you are self-motivated, possess demonstrated learning agility, and are passionate about delivering high-quality work products - we want to hear from you.
We lead with technical expertise, but that is just the tip of the iceberg - the 'Why' matters. At Platinum, we don't hire people to do a job. We provide professional and leadership development to complement our self-motivated domain experts. Our teammates are dot-connecting leaders that operate in a mutually accountable environment to deliver thought leadership, expert technical analysis, and quality execution for our clients.
This position requires an active U.S. Government Security Clearance at the TS/SCI level with CI polygraph.
You.
Platinum Technologies is seeking a Senior Developer to join our team. In this position you will design, develop, and maintain mission-critical applications that support Object-Based Intelligence (OBI) mission requirements, enterprise ontologies, knowledge graphs, and semantic data integration.
The Senior Developer serves as a senior technical contributor responsible for developing secure, scalable, and maintainable software solutions that enable semantic data integration, object management, and advanced analytics. This position develops application services, APIs, user interfaces, and backend components that leverage enterprise ontologies, knowledge graphs, and Semantic Web technologies to support data interoperability and mission workflows. Working within an Agile DevSecOps environment, the Senior Developer collaborates with ontology engineers, software engineers, database engineers, data engineers, and Government stakeholders to deliver high-quality software that supports operational mission requirements.
What you get to do.
  • Design, develop, test, deploy, and maintain enterprise software applications supporting Object-Based Intelligence mission requirements.
  • Develop scalable backend services, RESTful APIs, and user-facing applications that integrate with ontology services, knowledge graphs, semantic databases, and enterprise data platforms.
  • Implement software solutions utilizing Semantic Web technologies, including RDF, OWL, and SPARQL, to support semantic search, data integration, and knowledge discovery.
  • Collaborate with ontology engineers, database engineers, data engineers, analysts, and Government stakeholders to translate mission requirements into software solutions.
  • Develop secure, containerized applications using modern software engineering principles and cloud-native technologies.
  • Integrate applications with relational databases, graph databases, messaging systems, and enterprise APIs to enable seamless access to mission data.
  • Participate in Agile development activities, including sprint planning, technical design reviews, code reviews, and backlog refinement.
  • Develop automated unit, integration, and regression tests while supporting continuous integration and continuous deployment (CI/CD) pipelines.
  • Troubleshoot and resolve software defects, optimize application performance, and ensure application scalability, reliability, and security.
  • Produce and maintain software design documentation, API specifications, technical implementation guides, and operational documentation.
  • Support AI/ML initiatives by developing software services that provide access to semantic data, contextual knowledge, and enterprise analytics capabilities.
  • Mentor junior developers and provide technical guidance to project team members while supporting knowledge transfer activities with Government personnel.

Required Skills.
  • Must be a U.S. citizen and have an active TS/SCI with CI polygraph.
  • Minimum ten (10) years of experience and an advanced degree or 15 years of experience with a bachelor's degree.
  • Demonstrated experience developing enterprise software applications using Java, Python, C#, or comparable object-oriented programming languages.
  • Experience developing RESTful APIs, microservices, and distributed applications.
  • Experience integrating applications with relational databases, graph databases, or enterprise data platforms.
  • Experience with containerization technologies such as Docker and Kubernetes/OpenShift.
  • Familiarity with Agile software development methodologies, DevSecOps practices, CI/CD pipelines, and Git-based version control.
  • Ability to communicate complex technical concepts effectively to technical and non-technical stakeholders.

The Company is an Equal Opportunity/Affirmative Action employer. All qualified candidates will receive consideration for employment without regard to disability, protected veteran status, race, color, religious creed, national origin, citizenship, marital status, sex, sexual orientation/gender identity, age, or genetic information.
We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
