Each day U.S. Customs and Border Protection (CBP) oversees the flow of people, capital, and products that enter and depart the United States via air, land, sea, and cyberspace. The volume and complexity of border crossings require solutions to aid officers in detecting threats while promoting efficient trade and travel. The strongest applicant will have a proven track record of delivering production-ready enterprise applications used in the field and by mission-support entities.

In this role, you will design, develop, test, deploy, and maintain complex applications and services.

You will leverage your expertise across the full technology stack, with a strong focus on robust backend development using Java, while also contributing to frontend implementation. You will apply modern software development practices, including comprehensive unit testing, version control, and CI/CD pipelines to ensure high-quality, automated software delivery. As an SME, you will participate in architectural decisions, mentoring junior developers, and driving best practices within the team.

Some formal training exists to support building knowledge of missions and data-driven solutions, but much of the knowledge is gained through on-the-job training and individual initiative.

Technical knowledge must be augmented with rapid acquisition of mission knowledge and demonstrated commitment to positive mission outcomes; therefore, we seek self-starters capable of independent exploration, knowledge acquisition, informal support network development, and an appreciation for safeguarding the Nation’s borders.

Responsibilities include but are not limited to:

• Lead and perform development and maintenance of end-user focused, object-oriented, data-driven analytic applications to support CBP threat analysis and targeting in an agile environment.
• Contribute to all phases of the software engineering lifecycle (SELC), including requirements gathering, architecture design, coding, testing, deployment, and maintenance.
• Develop and consume RESTful APIs and ensure seamless integration between front-end and back-end systems.
• Develop new code, modify existing application code, conduct unit and system testing, and document developed and delivered application use cases, data flows, and functional operations.
• Develop, manage, and optimize CI/CD pipelines (e.g. using Jenkins, Git Lab CI, Harness) for automated builds, testing, and deployments.
• Demonstrate practical understanding to integrate rapid deployment of AI/ML services into the application delivery framework for targeting.
