Integration Subject Matter Expert

SAIC is seeking an experienced Integration Subject Matter Expert (SME) to support a mission-critical modernization program delivering a modular, adaptable software suite of essential capabilities across multiple warfighting functions. In this role, you will serve as the technical authority responsible for ensuring seamless integration of complex software systems, data services, and third-party capabilities across a modern, open-architecture framework spanning enterprise cloud and tactical edge environments.


This position operates across cloud and tactical edge environments, supporting integration planning, execution, and validation across the full software development lifecycle — from initial architecture through fielding — in both garrison and deployed settings, including Denied, Degraded, Intermittent, and Low Bandwidth (DDIL) environments.

The work is to be performed at the customer site at Aberdeen Proving Ground (APG), MD.

This role is contingent upon award news in Fall 2026.

Key Responsibilities:

• Lead integration planning, design, and execution across enterprise cloud and tactical edge environments, ensuring seamless interoperability between systems, data services, and third-party applications within an open-architecture framework


• Translate integration requirements into technically sound interface control documents, API specifications, and data exchange agreements that support bi-directional, cross-platform data sharing across classified and unclassified network domains


• Serve as the primary technical liaison between Government stakeholders, vendors, and development teams to ensure integration requirements are accurately captured, communicated, traceable, and verifiable throughout the program lifecycle


• Evaluate and validate platform integration capabilities including data onboarding and normalization, credential authority, object databases, API performance, and interoperability across multiple security domains


• Support development and validation of tactical edge configurations, ensuring integration approaches account for operations in DDIL environments 


• Participate in product demonstrations, design reviews, and agile development cycles, providing rapid technical assessment of integration solution compliance against documented requirements and operational needs


• Collaborate with vendors, partners, requirements analysts, and Government stakeholders to identify and resolve integration risks, dependencies, and technical gaps throughout the program lifecycle
