VistA Subject Matter Expert

What You’ll Do:

• Provide subject matter expertise supporting VA VistA systems, workflows, and modernization initiatives.
• Review generated MUMPS code, Fileman definitions, business rules extractions, and system documentation for accuracy and completeness, identifying errors, omissions, or misrepresentations against actual VistA behavior and VA configuration before outputs are used by development or architecture teams.
• Review generated workflow diagrams, process documentation, and clinical or administrative procedure descriptions for correctness against actual VA operational practices, flagging gaps or inaccuracies that could affect modernization design decisions.
• Advise technical and program teams on VistA architecture, functionality, dependencies, and operational processes.
• Support analysis and modernization of legacy MUMPS-based healthcare applications and integrations.
• Collaborate with architects, developers, infrastructure teams, and business stakeholders to support modernization and migration strategies.
• Assist with requirements gathering, workflow analysis, and system impact assessments related to VistA environments.
• Support interoperability initiatives involving legacy and modern healthcare systems.
• Provide expertise related to clinical, administrative, and operational healthcare processes supported within VistA.
• Assist with troubleshooting, root cause analysis, and resolution of complex VistA-specific issues including MUMPS code defects, Fileman data anomalies, RPC failures, and VA configuration problems—drawing on direct knowledge of VistA internals to identify root causes that generic and workflow issues.
• Support data mapping, interface analysis, and integration efforts involving VistA Fileman structures, MUMPS globals, RPCs, and VA-specific data configurations and enterprise systems.
• Participate in modernization planning sessions, architecture reviews, MUMPS and modernized code reviews, and interface design reviews, testing activities, and implementation efforts.
• Develop and review technical documentation, workflow diagrams, process documentation, and operational procedures.
• Support stakeholder communication and provide guidance to both technical and non-technical audiences regarding VistA-related functionality and modernization impacts.
• Assist with knowledge transfer and mentoring activities across project teams.

What We’re Looking For:

• Bachelor’s degree in Information Technology, Healthcare Administration, Computer Science, Engineering, or related discipline; equivalent experience may be considered.
