Leidos is seeking a Systems Interface Designer to join the Defense Healthcare Management System Modernization (DHMSM) program engineering team. The successful candidate will provide technical leadership for interface planning, integration, validation, and deployment activities supporting the migration of MHS GENESIS capabilities to Oracle Cloud Infrastructure (OCI). This position will coordinate activities across engineering teams, product teams, program management offices, vendors, and other technical stakeholders to ensure interfaces and boundary systems are prepared for migration and production cutover. The role will also support the definition, implementation, deployment, and sustainment of new capabilities within the MHS GENESIS electronic health record environment.

Primary Responsibilities

• Lead a recurring, cross-functional technical working group supporting OCI migration planning, interface readiness, testing, and cutover activities.

• Serve as a primary coordination point among engineering teams, product owners, program management offices, vendors, and external stakeholders responsible for MHS GENESIS boundary, or B-side, systems.

• Define and communicate stakeholder roles, responsibilities, dependencies, milestones, and completion criteria for assigned interfaces and boundary systems.

• Develop and maintain integrated interface plans, schedules, readiness criteria, action items, risks, issues, and dependencies across production and non-production environments.

• Prioritize and coordinate line-of-sight testing, connectivity verification, interface validation, and operational-readiness activities in preparation for OCI migration and cutover events.

• Assess existing interfaces and integration dependencies to identify migration impacts, technical gaps, compatibility concerns, and potential risks to system interoperability.

• Develop, review, and maintain Interface Control Documents, interface design specifications, data-flow diagrams, technical requirements, configuration documentation, and operational runbooks.

• Ensure interface documentation accurately captures source and target systems, data elements, message flows, connectivity requirements, transformation rules, security requirements, error-handling procedures, and operational dependencies.

• Coordinate interface design, configuration, implementation, testing, deployment, and post-deployment validation activities throughout the migration lifecycle.

• Support the development and execution of interface test plans, validation procedures, defect-management processes, and production-readiness assessments.

• Analyze test results and technical issues, facilitate defect triage, and coordinate corrective actions with development, infrastructure, cybersecurity, database, application, and vendor teams.

• Verify that interfaces and boundary systems meet established technical, performance, security, availability, and operational-readiness requirements before deployment.

• Support cutover planning, including interface sequencing, implementation procedures, rollback plans, production verification, and post-cutover stabilization activities.

• Provide technical input during architecture reviews, design reviews, technical interchange meetings, configuration-management boards, and migration-readiness reviews.

• Translate complex technical requirements, system dependencies, and migration impacts into clear, actionable information for technical and non-technical stakeholders.

• Collaborate with product owners, systems engineers, solution architects, cloud engineers, developers, testers, cybersecurity personnel, and subject-matter experts to resolve interface and integration challenges.

• Work within an Agile engineering environment and provide regular status updates, technical recommendations, risk assessments, and decision-support information to program leadership.

• Promote consistent interface engineering practices, documentation standards, validation methods, and configuration-management processes across participating teams.

• Support the sustainment and continuous improvement of interfaces following deployment, including troubleshooting, performance monitoring, root-cause analysis, and implementation of corrective actions.

Minimum Qualifications

• Bachelor’s degree in Systems Engineering, Computer Science, Information Systems, Engineering, Health Informatics, or a related discipline with 8–12 years of relevant experience; additional experience may be considered in lieu of a degree.

• At least five years of recent experience leading systems integration, interface engineering, cloud migration, technical delivery, or full-lifecycle system implementation efforts.

• Must be a U.S. citizen with an active ADP/IT-II Public Trust clearance based on a minimum Tier 3 investigation, as required by the federal government. Contract requirement.

• Demonstrated experience coordinating complex technical activities across multiple engineering teams, vendors, government organizations, and program stakeholders.

• Experience supporting cloud migration initiatives, including assessment, planning, design, testing, cutover, validation, and post-deployment stabilization.

• Experience designing, documenting, implementing, testing, or sustaining interfaces between complex enterprise systems.

• Experience developing and maintaining Interface Control Documents, interface specifications, system diagrams, integration plans, test documentation, and technical requirements.

• Experience conducting interface, connectivity, interoperability, or end-to-end validation in production and non-production environments.

• Working knowledge of systems engineering, systems integration, configuration management, requirements management, verification and validation, and risk-management practices.

• Ability to analyze complex technical dependencies, identify risks and gaps, develop mitigation strategies, and drive issues to resolution.

• Strong written and verbal communication skills, including the ability to lead technical working groups and communicate effectively with engineering teams, customers, vendors, and senior program stakeholders.

• Ability to manage multiple priorities, coordinate interdependent activities, and deliver results within established schedules and migration milestones.

Preferred Qualifications

• Experience supporting Oracle Cloud Infrastructure migration, modernization, integration, or sustainment activities.

• Experience supporting MHS GENESIS, Oracle Health/Cerner Millennium, Department of War healthcare systems, or another large-scale electronic health record environment.

• Experience integrating commercial off-the-shelf applications within a large, complex federal enterprise environment.

• Knowledge of healthcare interoperability standards, integration engines, APIs, web services, messaging technologies, or healthcare interface protocols.

• Experience supporting interface test events, operational-readiness reviews, production cutovers, post-deployment validation, and system stabilization.

• Familiarity with Department of War systems engineering, configuration management, cybersecurity, change control, and technical-review processes.

• Experience with technical requirements and work-management tools such as Jira, Confluence, ServiceNow, DOORS, or similar platforms.
