Responsibilities include designing secure application architectures, developing RESTful services and APIs, building responsive user interfaces, integrating with mission systems, and supporting deployment pipelines in secure environments.
This position emphasizes Java full stack development, secure coding, CI/CD automation, and compliance with DoD cybersecurity requirements. Developers will work closely with system engineers, cybersecurity teams, database administrators, and mission stakeholders to deliver resilient, high-performing solutions that support critical intelligence operations.
Key Responsibilities
Design, develop, test, and maintain full stack enterprise applications with a primary focus on Java/J2EE development
Develop robust back-end services using Java, Spring Boot, Spring Framework, Hibernate/JPA, and RESTful API architectures
Build and enhance front-end interfaces using JavaScript, TypeScript, and modern frameworks such as Angular, React, or similar technologies
Develop and optimize relational database solutions using Oracle, PostgreSQL, MySQL, and SQL query tuning
Design and implement microservices-based architectures and secure API integrations across enterprise platforms
Support DevSecOps pipelines including automated builds, testing, code quality validation, vulnerability scanning, and deployments
Implement secure coding practices aligned with DoD cybersecurity policies, RMF requirements, and vulnerability remediation processes
Integrate applications with cloud services, enterprise platforms, and mission-critical intelligence data sources
Troubleshoot application defects, performance bottlenecks, and production issues across front-end and back-end systems
Participate in Agile development activities including sprint planning, code reviews, backlog refinement, and release planning
Produce and maintain technical documentation including architecture diagrams, API documentation, deployment guides, and configuration management artifacts
Required Qualifications
Active Top Secret clearance with SCI eligibility
DoD IAT Level II certification or higher (e.g., Security+ CE, CASP+, or equivalent)

Strong proficiency in:
Java, J2EE, Spring Boot, Spring Framework
RESTful web services and API development
Front-end development using JavaScript, TypeScript, Angular, or React
SQL development using Oracle, PostgreSQL, MySQL, or similar platforms
Experience working in a DevSecOps environment, including CI/CD pipeline implementation and sustainment
Familiarity with source control and configuration management tools such as Git, GitLab, or GitHub
Experience with secure coding standards, application security, and vulnerability remediation
Desired Qualifications
5+ years of experience in Full Stack Java development within DoD or Intelligence Community environments
Experience with microservices architecture, API gateway integration, and service-oriented design
Familiarity with Docker, Kubernetes, OpenShift, or containerized application deployments
Experience supporting RMF, system accreditation, and Authority to Operate (ATO) processes
Knowledge of AWS, Azure, or DoD cloud environments
Experience with message brokers, event-driven architecture, and enterprise integration patterns
