Network site design intern

The Network Site Design (NSD) Team at Leidos has an opening for an intern to help us modernize how network site designs are developed and delivered. This is an exciting opportunity to gain hands-on experience supporting the Service Management, Integration, and Transport (SMIT) contract, the Department of the Navy's largest IT services contract. Under SMIT, Leidos delivers and sustains the backbone of the Navy Marine Corps Intranet (NMCI), providing services such as network site infrastructure design, network architecture, configuration management, and digital engineering. The successful candidate will support the NSD team in designing, documenting, and supporting the implementation of critical network infrastructure solutions that enable naval operations worldwide, while gaining exposure to modern digital engineering methodologies, including Model-Based Systems Engineering (MBSE).

Primary Responsibilities

• Support the development and review of change requests for network site designs and associated technical documentation for infrastructure projects across multiple naval installations
• Assist with network site topology design and documentation, including site layout development, network device placement, and logical/physical topology diagrams
• Work with the Active Bill of Materials (ABOM) to track network equipment, validate component specifications, and maintain accurate inventory records for site implementations
• Participate in network architecture planning activities, including site connectivity design, routing protocols, and network segmentation strategies
• Collaborate with network architects and engineers to develop site-specific designs that align with enterprise architecture standards and best practices
• Support the preparation of network design templates in Cameo Systems Modeler and help ensure compliance with NSD procedures and standards
• Assist with site survey validations, network solution assessments, and evaluations for infrastructure upgrade projects
• Participate in digital engineering initiatives, including curating designs in Cameo Systems Modeler and learning MBSE methodologies for network architecture modeling
• Contribute to the development and maintenance of Standard Operating Procedures (SOPs), network design documentation, and technical guides for site topology standards
• Help process implementation feedback from field teams and support post-deployment validation activities
• Verify data integrity of network device inventories, site topology databases, and ABOM records
• Attend team meetings and collaborate with network engineering, operations, and quality assurance teams

Basic Qualifications

• Currently enrolled in an accredited bachelor's or master's degree program in Engineering (any discipline), Computer Science, Information Technology, Network Engineering, or a related technical field
• Cumulative GPA of 3.0 or higher on a 4.0 scale
• Technical knowledge or coursework in one or more of the following areas: network design and architecture, systems engineering, database management, or IT infrastructure
• Strong attention to detail and the ability to follow technical procedures accurately
• Effective written and verbal communication skills
• Ability to work both independently and collaboratively in a team environment
• U.S. citizenship and the ability to obtain and maintain a Secret security clearance

Preferred Qualifications

• Experience with database management, data analysis, or configuration management tools
• Knowledge of network infrastructure components (routers, switches, firewalls, load balancers, wireless access points)
• Understanding of network topologies and site connectivity architectures
• Familiarity with Bill of Materials (BOM) processes and inventory management systems
• Exposure to Model-Based Systems Engineering (MBSE) concepts or tools (e.g., Cameo Systems Modeler, SysML, Teamwork Cloud)
• Understanding of IT service management frameworks or processes
• Experience with network diagramming tools (e.g., Microsoft Visio or similar)
• Experience with Microsoft 365 (Office, SharePoint, Teams) or similar collaboration platforms
• Coursework or projects involving network architecture, network design, site planning, or infrastructure topology
• Interest in pursuing a career in network engineering, network architecture, or IT infrastructure design
• Previous internship or co-op experience in a technical or networking environment
