Full Job Description

Department
Information Technology

We are seeking a highly motivated Network Engineer to join our team!

We partner with the U.S. national defense community to create fully integrated, resilient, and innovative digital solutions that enable smart, real-time decision-making. We work with our customers on everything from conquering their data to improving and safeguarding IT infrastructure. Our ultimate goal is to enhance the nation’s ability to identify, address, and act — no matter what challenges arise.

Location: On-Site in Indian Head, MD
Clearance: Secret clearance required

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

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

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 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

Enable secure OT data flows, including:

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

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

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

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
Strong hands-on background with:

– 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

Experience working in air-gapped or highly restricted environments
Familiarity with DoD / Navy cybersecurity expectations, including designing systems that can be certified
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
Excellent communication skills

Equal Opportunity Employer

All employment opportunities are made without regard to age, race, creed, color, religion, sex, national origin, ancestry, disability status, veteran status, sexual orientation, gender identity

Job Type: Full-time

Pay: $150,000.00 - $165,000.00 per year
