System Integration: Integrate mobile applications with backend enterprise systems, databases, and real-time data feeds to provide actionable intelligence to personnel in the field.
UI/UX Design: Create intuitive user interfaces optimized for field use, ensuring high usability under varying operational conditions.
Maintenance & Optimization: Monitor application performance, troubleshoot issues, and implement updates to ensure continuous availability and reliability.

Minimum Qualifications:

Degree in Computer Science, Engineering, or a related technical field. BS/BA and 7+ years or MS/MA/MBA and 5+ years or PhD/Doctorate and 3+ years.
Hands on experience in mobile application development (Swift, Kotlin, React Native, or Flutter).
Proficiency in RESTful APIs, mobile security protocols, and cloud-based backend services (e.g., AWS GovCloud, Azure Government).
Knowledge of mobile data storage and testing frameworks.
Demonstrated ability to develop software solutions for complex, high-stakes operational environments.

Preferred Qualifications:

Experience developing applications for federal law enforcement or defense agencies.
Knowledge of mobile device management (MDM) solutions and secure containerization.
Experience with offline-first application architecture for use in remote or low-connectivity areas.
Familiarity with Agile/DevSecOps methodologies.
Experience with Atlassian suite of tools such as Jira and Confluence.

Clearance Requirements:

Must be a U.S. citizen with a current/active Top-Secret clearance and the ability to obtain and maintain DHS CBP suitability prior to starting this position.
