• Modify and enhance VistA/MUMPS applications to eliminate or replace SSN usage within business processes, user interfaces, reports, audit trails, and related functionality while implementing approved approaches for transitioning to enterprise identifiers.
• Analyze existing VistA routines, data structures, workflows, and application dependencies to identify affected functionality, troubleshoot defects, and implement secure, maintainable code consistent with VA and project development standards.
• Develop and execute unit tests and support functional, integration, regression, User Acceptance Testing, deployment validation, and production-readiness activities to ensure modifications preserve existing functionality and meet approved requirements.
• Collaborate with Quality Assurance personnel to investigate defects, implement corrections, verify resolutions, and support post-release troubleshooting and application stability.
• Follow secure software development and sensitive-data-handling practices when working with PII and PHI, support applicable VA privacy, security, and NIST control requirements, and produce technical documentation describing application changes and implementation considerations.
• Collaborate with Lead Developers, Business Analysts, Product Owners, QA personnel, cybersecurity teams, and other stakeholders within an Agile environment, participating in Sprint Planning, backlog refinement, daily stand-ups, Sprint Reviews, and Retrospectives while communicating estimates, technical issues, dependencies, and risks.

• Strong hands-on experience programming within VistA using MUMPS/M and InterSystems Caché, GT.M, or a comparable M-based platform.
• Experience modifying or supporting VistA packages, modules, data structures, or other healthcare information systems, including analysis of existing routines, workflows, and application dependencies.
• Experience with software debugging and troubleshooting, source control, peer code review, unit and integration testing, and Agile software development practices.
