Role Overview This role is responsible for the end-to-end design, implementation, and evolution of a secure, private, air-gapped OT network. The engineer will be the initial and sole network authority, owning technical decisions from assessment through deployment, with designs reviewed and certified by external stakeholders.
Core Responsibilities Assess the existing network and industrial infrastructure, including switches, firewalls, cabling, and servers, to determine:
Hardware reuse opportunities
Upgradability and lifecycle risks
Security and compliance gaps relative to DoD / Navy standards
Security posture and compliance risk
Operational reliability and uptime
Cost, procurement lead time, and vendor supportability
OT Network Design Design a private, air-gapped OT network architecture from the ground up, including:
VLAN and subnetting strategy aligned to industrial control boundaries
Secure zoning between PLCs, HMIs, control rooms, and server rooms
Isolation between multiple control/manufacturing groups with no lateral communication
Private 5G Backbone Integration Architect and implement a private OT network that integrates with a newly deployed private 5G backbone being built and operated by a separate team, integrating:
Private 5G connectivity between control rooms, server rooms, and operational areas
Fiber connectivity from manufacturing buildings to their associated control rooms
Clear security boundaries between wireless, fiber, and core infrastructure
Hands-On Implementation Hands‑on implementation of all network infrastructure, including:
Racking, cabling, labeling, and power coordination
Configuration of Cisco and Dell network equipment
Firewall rules, routing, switching, and management plane access
PLC → HMI communication within control rooms
Controlled PLC/HMI data forwarding to centralized server infrastructure
Protection of industrial systems from unintended access or broadcast traffic
Documentation Produce and maintain authoritative network documentation to support compliance certification, including:
Logical and physical network diagrams
IP address management and VLAN maps
As‑built and as‑designed artifacts
Clear security boundaries and documentation for RMF/STIG review
Logging, segmentation, and access controls required for auditability
Scalable Platform Build the network as a scalable platform, not a one‑off deployment, ensuring:
Additional control/manufacturing groups can be added with minimal redesign
Capacity, addressing, and segmentation can evolve over time
Technical Authority Serve as the technical authority for network decisions, working with stakeholders to:
Explain trade‑offs and risks clearly
Support procurement, installation, and acceptance activities
Guide future expansion and modernization efforts Required Experience & Skills
Minimum of 5 years’ experience as a hands‑on network engineer
Proven experience designing and implementing industrial / OT networks

Understanding of PLC, HMI, and industrial data flows
Ability to operate independently and make sound technical decisions with minimal oversight
Strong documentation and communication skills
Bachelor’s degree from an accredited college or university in Computer Engineering, Computer Science, Cybersecurity, or related discipline, or equivalent military experience
Minimum of DoD 8140 / DoD 8570 IASAE Level II certification
Strong attention to detail and organizational skills
Strong Hands-On Background
Enterprise switches and firewalls (Cisco and Dell preferred)
Server configuration (Linux and Windows), Windows workstations
Fiber and copper cabling in industrial environments
VLANs, subnetting, routing, and network segmentation
