CACI is currently looking for a Full Stack Developer with agile methodology experience to join our BEAGLE (Border Enforcement Applications for Government Leading-Edge Information Technology) Agile Solution Factory (ASF) Team supporting Customs and Border Protection (CBP) client located in Northern Virginia! Join this passionate team of industry-leading individuals supporting the best practices in Agile Software Development for the Department of Homeland Security (DHS). In this vital role, you will apply your expertise to develop high-impact applications directly supporting critical CBP operations. Utilizing React for crafting intuitive and responsive user interfaces, and Spring Boot for building robust, scalable, and secure back-end services, you will also be instrumental in designing and implementing event-driven middleware to facilitate seamless messaging across multiple internal and external services supporting border missions. Your work will directly translate into tangible improvements for national security and the protection of American citizens. What you’ll get to do: Full-Stack Development Leadership: Architect, design, develop, test, and deploy robust and scalable full-stack applications and features for both modernized and legacy systems. This includes hands-on development across front-end (UI/UX implementation using React), middle-tier (API development), and back-end (database interaction and business logic using Spring Boot) components with minimal supervision. Agile Collaboration & Contribution: Actively participate and contribute to all Agile Scrum ceremonies, including daily stand-ups, sprint planning, backlog refinement, sprint reviews, and retrospectives. Collaborate effectively with cross-functional teams to define requirements, estimate tasks, and deliver committed sprint goals. Code Quality & Best Practices: Promote and ensure high standards of code quality through rigorous code reviews, automated testing (including collaboration with Automated Test Engineers on tools like Selenium for end-to-end testing, alongside unit and integration tests), and continuous integration/continuous delivery via Harness (experience with pipeline development is crucial). Leverage tools like SonarQube for static code analysis and adherence to secure coding practices. Contribute to the development and refinement of software engineering guidelines and best practices. System Integration & Optimization: Design and implement robust APIs, microservices, and event-driven messaging solutions for seamless integration between various system components and external services. Optimize application performance, scalability, and security across all layers of the stack, ensuring high availability for critical border missions. Technical Problem Solving: Proactively identify, diagnose, and resolve complex technical issues and architectural challenges. Provide technical guidance and innovative solutions to enhance system reliability and efficiency. Continuous Improvement: Contribute to the continuous improvement of development processes, tools, and technologies. Stay current with emerging industry trends and evaluate their applicability to the project. Mentorship & Support: Support and collaborate with teammates, fostering a culture of shared responsibility and knowledge transfer to ensure collective product and team success.
