· Support applications designed to operate in offline or intermittently connected environments , including data replication, store-and-forward patterns, queue-based synchronization, and conflict resolution.

· Participate in Agile development activities, including backlog refinement, sprint planning, development, testing, code reviews, demonstrations, and defect remediation.

· Support CI/CD and DevSecOps pipelines , automated testing, vulnerability scanning, deployment, and release activities.

· Support application integration and API development with other DoD systems and services.

· Assist with troubleshooting production and sustainment issues and implement patches, bug fixes, and approved enhancements.

· Support DoD cybersecurity and compliance requirements, including ATO, RMF, STIG, CAC/PKI authentication, and continuous compliance activities.

The PWS specifically requires Agile development, software updates to address defects/test results, and CI/CD pipelines incorporating testing, security scanning, compliance and deployment automation.
