 * Experience collecting, interpreting, and documenting information from architecture models.
 * Experience drafting architecture artifacts, technical documentation, interface documentation, models, diagrams, roadmaps, or related engineering materials.
 * Experience architecting systems within relevant mission domains such as space systems, air systems, intelligence systems, C4ISR, or similar DoD or Intelligence Community environments.
 * Experience defining interfaces and supporting integration across multiple independent systems, services, stakeholders, or mission domains.
 * Familiarity with SysML, UML, UAF, MBSE tools, interface control documents, data models, or sequence diagrams.

## Description

Apex Systems is currently hiring a Systems of Systems Architect with a large federal client. This individual will define and evolve the end-to-end architecture for a complex ecosystem of interconnected systems, services, and platforms. The System-of-Systems Architect will work closely with government stakeholders, program leadership, systems engineers, software teams, cybersecurity specialists, and operational users to ensure diverse systems integrate into a cohesive, resilient, and scalable mission capability.

Project Details / Mission Supported:

 * Support the DIFC2 project under the CBC2 program, an Air Force initiative associated with the ABMS IDIQ.
 * Contribute to a software acquisition program focused on enabling and executing low-range kill chains.
 * Develop and maintain system-of-systems architecture across operational, logical, physical, and data views.
 * Collect, analyze, and translate information from architecture models into actionable engineering and program recommendations.
 * Define end-to-end system interfaces, integration patterns, and data exchanges across multiple systems and mission domains.
 * Create and maintain architecture artifacts using DoDAF, Model-Based Systems Engineering methodologies, and applicable modeling approaches.
 * Lead architecture trade studies, alternatives analyses, and technology assessments to support modernization and capability evolution.
 * Ensure traceability from mission objectives and operational needs through requirements, architecture, design, integration, and implementation.
 * Partner with systems engineers, MBSE modelers, software teams, and cybersecurity professionals to align architecture models with implementation roadmaps.
 * Develop architecture roadmaps, transition plans, technical insertion strategies, interface documentation, and support technical materials.
 * Support technical reviews and governance activities, including SRR, PDR, CDR, TRR, and architecture review boards.
 * Provide technical leadership to small engineering teams and communicate architectural concepts to both technical and non-technical stakeholders.
