Leidos Digital Modernization Sector is looking for a Systems Engineering and Integration (SE&I) Draftsman to work on the Army Global Unified Network (AGUN) program. The Global Enterprise Network Modernization – OCONUS (GENM-O) is a critical mission provider responsible for keeping the Army connected through global network modernization projects. The AGUN modernization effort will unify the next generation of Army transport to comply with the Joint Regional Security Stack (JRSS) divestiture mandate. A phased systematic approach is required to provide individual sites with standardized, updated technology systems to ensure the Army’s Information Technology (IT) infrastructure is equipped to provide soldiers with cutting-edge technology to ensure applications, data, and enterprise services are accessible, trusted, and interoperable across the globe.

The SE&I Draftsman will support the program by developing and maintaining detailed technical drawings, architecture diagrams, and integration documentation in support of system-of-systems engineering efforts. This position plays a vital role in visualizing and documenting system designs, data flows, physical layouts, and interface connections that align with Army, MIL-STD, and government configuration management requirements.

The ideal candidate will work collaboratively within a multidisciplinary engineering team, supporting efforts across the system lifecycle, from concept development and design to test, fielding, and sustainment to ensure the Army’s Information Technology (IT) infrastructure is equipped to provide soldiers with cutting-edge technology across the globe.

Primary Responsibilities:

• Produce detailed system drawings, network schematics, interface control diagrams (ICDs), and equipment integration layouts in support of SE&I activities.

• Translate engineering concepts, requirements, and technical data into compliant documentation and visual design artifacts.

• Support architecture development under Army NETCOM and Model-Based Systems Engineering (MBSE) frameworks, ensuring accurate representation of operational, system, and technical views.

• Maintain version control of drawings, ensuring traceability within the Configuration Management (CM) process and alignment with program baselines.

• Collaborate with systems engineers, network engineers, and program integrators to capture evolving system configurations and design updates.

• Prepare drawing packages and integration documentation for System Design Reviews (SDRs), Preliminary Design Reviews (PDRs), and Critical Design Reviews (CDRs).

• Ensure drawing accuracy and compliance with GENM-O data deliverables (e.g., CDRLs, SOW requirements).

• Support rack elevations, cabling diagrams, and hardware layouts for systems integration facilities and deployed environments.

• Manage drawing repositories, apply CM identifiers, and ensure technical documentation meets MIL-STD-31000, MIL-HDBK-61A, or program-specific standards.

Basic Qualifications:

• US Citizen with a Secret security clearance.

• DoD 8570 certifications.

• IAT II, OS.

• Bachelor’s degree in Drafting, Engineering Technology, or a related discipline, minimum 3 years of experience supporting technical drafting within a DoD or government contracting environment.

• Proficiency in AutoCAD, Visio, or other CAD/diagramming tools.

• Strong understanding of systems engineering and integration processes.

• Excellent attention to detail, technical accuracy, and ability to interpret engineering data and system specifications.

• Strong teamwork and communication skills in a classified or controlled environment.

• Excellent written and verbal communication skills

• Ability to collaborate with cross-functional stakeholders

Preferred Qualifications:

• Experience supporting C4ISR, network modernization, or defense system integration programs.

• Knowledge of SysML, Cameo Enterprise Architect, or other Model-Based Systems Engineering (MBSE) tools.

• Familiarity with MIL-STD-973, EIA-649, or ANSI Y14.5 standards for engineering documentation.

• Experience supporting Integrated Product Teams (IPTs) and SE&I frameworks.
