What is network security?

Network security refers to the strategies, policies, and technologies used to protect computer networks from unauthorized access, misuse, or theft. It involves implementing measures such as firewalls, encryption, intrusion detection systems, and secure protocols to safeguard data and ensure the integrity, confidentiality, and availability of network resources. Network security is essential for organizations to prevent cyberattacks, data breaches, and other security threats that can disrupt operations or compromise sensitive information.

What is the difference between Network Security vs Cybersecurity Specialist?

AspectNetwork SecurityCybersecurity Specialist
CertificationsCompTIA Security+, Cisco CCNA SecurityCompTIA Security+, CISSP, CEH

Job description

Network Engineer / Network Architect (OT / ICS - DOE Energy Sector)
 

Make an Impact in America's Energy Future

Are you passionate about building secure, resilient networks that keep critical infrastructure running safely and reliably? Do you thrive in environments where precision, safety, and mission-driven engineering truly matter? If so, we want you on our team.

We're looking for a talented Network Engineer / Network Architect to help modernize and secure Operational Technology (OT) and Industrial Control System (ICS) environments that support some of the nation's most critical energy-sector operations. This is a chance to work at the crossroads of advanced engineering, cybersecurity, and national mission support-directly contributing to safe, efficient operations across nuclear, highvoltage, and facilityscale systems.

What You'll Do

Design the OT Networks That Power Critical Operations
Architect secure, segmented OT/ICS networks using the Purdue Model (Levels 0-3)
Develop highavailability, deterministic designs supporting SCADA, PLCs, DCS, historians, and realtime automation
Implement secure vendor/remote access pathways aligned to cybersecurity frameworks
Build zoning, conduits, DMZs, and trusted dataflow architectures for mission operations
Design and support industrial protocol environments (Modbus, DNP3, EtherNet/IP, OPCUA, Profinet, IEC 61850, BACnet)

Engineer, Deploy, and Operate OT Infrastructure
Configure and maintain industrialgrade switches, routers, firewalls, and ruggedized hardware
Support facility systems such as building automation, utilities, power systems, and nuclear/experimental equipment
Maintain diagrams, inventories, IP schemas, and documentation aligned with cybersecurity and configuration controls

Advance OT Cybersecurity & DOE Compliance
Apply NIST 80082, NIST 80053/171, and ISA/IEC 62443 security controls
Support DOE readiness activities, audits, and assessment documentation
Collaborate with Cybersecurity teams on firewall policies, monitoring, logging, and threat detection
Support vulnerability management while maintaining operational uptime in sensitive environments

Automate, Monitor & Sustain Critical Systems
Build automation workflows (Ansible/Python) where safe and appropriate
Integrate network health and security telemetry using approved OT monitoring platforms (Nozomi, Claroty, Splunk, SolarWinds, ELK/Grafana)
Develop crisp documentation, changecontrol packages, and incident response materials

What You Bring

Required:
5-10+ years in network engineering/architecture, including 3+ years supporting OT/ICS in critical infrastructure
Experience with:
- SCADA, historians, PLC/DCS systems
- Industrial protocols such as Modbus, DNP3, EtherNet/IP, OPCUA, Profinet
- NIST 80082, NIST 80053/171, and related frameworks
- Industrial network gear (Cisco IE/Stratix, Hirschmann, Moxa)
- OT firewall/DMZ architecture (Palo Alto, Fortinet, ASA)
Experience in energy, utilities, nuclear, national labs, or similarly highsecurity sectors
Strong collaboration with Controls, Facilities, Cybersecurity, and mission support partners

Preferred:
Certifications such as CCNP/CCIE, GICSP, ISA/IEC 62443, CISSP, PCNSE
Experience with OT cybersecurity platforms (Nozomi, Claroty, Dragos)
Background supporting DOE or other highly regulated environments
Familiarity with cyber audits, readiness reviews, and facility safety/security protocols

Work Environment

Onsite role supporting plantfloor and missioncritical operations
Occasional 24/7 oncall participation
Travel to facilities, secured areas, or plant locations as needed
PPE and safety training required
Must be eligible for Q or L clearance

Success in This Role Looks Like

More resilient, visible, and secure OT network operations
Successful execution of Purdue Model and 62443aligned segmentation
Clear, consistent configurationmanaged network baselines
