Responsibilities
Network Design and Deployment:
Architect, implement, and maintain LAN/WAN/WLAN infrastructure across office and manufacturing environments using Cisco Meraki and Ubiquiti UniFi platforms.
OT Network Management:
Design and maintain segmented OT/IT network environments supporting industrial control systems, PLCs, and manufacturing floor devices. Enforce strict zone isolation in accordance with NIST and CMMC control families.
Security and Compliance:
Implement and enforce network security controls aligned with NIST and CMMC requirements, including access control, boundary protection, audit logging, and incident response.
Firewall and Segmentation:
Configure and manage firewalls, VLANs, ACLs, and micro‑segmentation policies to protect CUI and sensitive manufacturing data.
Monitoring and Troubleshooting:
Proactively monitor network health, respond to outages, and perform root cause analysis across both IT and OT segments.
VPN and Remote Access:
Administer and maintain secure remote access solutions including site‑to‑site and client VPN configurations, ensuring least‑privilege access.
Documentation:
Maintain detailed network diagrams, configuration baselines, change logs, and system security plans (SSPs) as required for CMMC assessments.
Cross‑Functional Collaboration:
Partner with Engineering, Operations, and IT teams to support network requirements for automation, data acquisition, and production systems.
Government and Compliance Support:
Support internal audits, CMMC assessments, and government contract compliance reviews with thorough documentation and evidence collection.

OT Network Experience:
Hands‑on experience designing or maintaining OT/IT converged networks including familiarity with industrial protocols (Modbus, EtherNet/IP, PROFINET) and IC‑SCADA network architecture.
Platform Proficiency:
Direct hands‑on experience with Cisco Meraki (switching, wireless, security appliances) and Ubiquiti UniFi (switches, APs, gateways) required.
Security Mindset:
Working knowledge of NIST 800‑171, CMMC, and network‑level controls. Experience supporting or preparing for CMMC assessments is strongly preferred.
Government Experience (Preferred):
Prior experience supporting federal contractors, DoD programs, or government‑adjacent facilities with CUI handling and export‑controlled environments (ITAR/EAR).
Routing and Switching:
Strong fundamentals in BGP, OSPF, spanning tree, VLANs, QoS, and SD‑WAN concepts.
Problem Solving:
Ability to diagnose and resolve complex network issues across both IT and OT environments with minimal downtime.
Physical Requirements:
Ability to lift up to 50 lbs, work in a manufacturing environment, and perform cable runs, rack installations, and equipment mounting.
Preferred Certifications:
