SAIC is seeking an Systems Integration Lead to serve as the primary engineering entry point for external systems, mission partners, data providers, and user communities seeking integration into the ecosystem. This individual will guide onboarding efforts from initial engagement through operational integration by coordinating the technical, cyber, infrastructure, test, and governance activities required for successful implementation.

The successful candidate will work across engineering, cyber, test, infrastructure, and program teams to define integration approaches, document interfaces and data flows, coordinate actions, and ensure integrations progress efficiently through the System Integration Process (SIP).

Job Duties Include

• Serve as the primary engineering point of contact for external systems, mission partners, and data providers seeking integration.
• Lead onboarding efforts by identifying integration requirements, data flows, interfaces, security considerations, and operational objectives.
• Own the lifecycle of external integrations from initial engagement through operational fielding, tracking status, risks, dependencies, and action items.
• Coordinate activities across systems engineering, cyber, test, architecture, infrastructure, operators, and government stakeholders.
• Develop and maintain integration artifacts, including OV-1s, SV-1s, SV-2s, data flow diagrams, interface diagrams, ICDs, and EICDs.
• Define and document external interfaces, data exchanges, ports, protocols, services (PPS), and integration dependencies.
• Assess connectivity requirements, UCI message exchange requirements, and operational impacts of new integrations.
• Facilitate external participation in technical reviews, working groups, architecture discussions, and governance activities.
• Coordinate with infrastructure and cyber teams to ensure integrations are prepared for testing, exercises, demonstrations, and operational use.
• Support the development of model-based representations of interfaces and integrations as the program matures its digital engineering capabilities.
• Serve as the communication focal point for external integrations, ensuring stakeholders understand requirements, progress, issues, and decisions.

Qualifications

Required Qualifications

• Bachelor's degree and fourteen (14) years or more of related experience; OR Master's degree and twelve (12) years or more of related experience; OR PhD and nine (9) years or more of related experience.
• TS/SCI clearance and U.S. citizenship.
• Experience supporting systems engineering, system integration, interface management, or technical onboarding of complex systems within DoD or Intelligence Community environments.
• Experience coordinating technical activities across engineering, cyber, infrastructure, operational, and program stakeholders.
• Experience developing architecture products such as OV-1, SV-1, SV-2, interface diagrams (ICD/EICD), or data flow diagrams.
• Understanding of system interfaces, data flows, messaging architectures, and PPS concepts.

Desired Qualifications And Experience

Experience documenting system integrations, external connections, and interface requirements

• Experience supporting command and control, battle management, ISR, air operations, space operations, or similar mission systems.
• Experience with OMS, UCI, XML, APIs, messaging systems, or machine-to-machine interfaces.
• Familiarity with Model-Based Systems Engineering (MBSE) tools and methodologies including Cameo, SysML, and Teamwork Cloud.
• Experience supporting ARBs, CCBs, requirements reviews, or engineering governance activities.
