Overview

Who We AreAt ERMCO, we energize the world by empowering people. Our team keeps your lights on and your future bright. We welcome innovation, test ideas fearlessly, and turn them into scalable, market-ready solutions. We are driven by purpose, aligned in our goals, and agile in the face of change. If you are ready to be part of a company with a strong legacy and an even stronger vision, we’re ready to meet you. Join a team where your career can trulyTRANSFORM.

Who Are You

The Senior Network Engineer will possess advanced expertise in enterprise networking and Fortinet technologies. This role is critical in designing, securing, and managing complex network infrastructures that support a high-availability manufacturing environment.

This role demands deep enterprise networking expertise, with advanced, hands-on Fortinet skills. Candidates must hold an NSE4 or higher certification, exceeding the baseline “Fortinet Certified Professional” level. Success requires real-world capability to independently manage and configure complex deployments. Fortinet experience must be on par with Palo Alto, and more advanced than Meraki or Ubiquiti. The largest challenge in this position is the ability to get into the cockpit of Fortinet and take off.

The ideal candidate brings expert-level network engineering experience and a proven track record of deploying and managing Fortinet infrastructure in complex environments. While knowledge of manufacturing systems is preferred, the key requirement is demonstrated hands-on experience with Fortinet technologies used to secure and administer enterprise networks. Candidates should have successfully implemented Fortinet solutions to manage and protect mission-critical systems and be motivated to expand their expertise in high-availability, security-focused environments. A strong fit for this role has demonstrated the ability to contribute creative ideas and help bring them to life through effective, real-world network engineering solutions.

**Remote or hybrid work flexibility with up to 50% travel required to company locations including Tennessee, Wisconsin, and Georgia; relocation assistance available if needed.

Responsibilities

What Will You Do

• Design, implement, and manage secure network infrastructure using Fortinet technologies, including FortiGate firewalls, SD-WAN, VPNs, and threat detection tools.
• Lead Fortinet deployments and configurations, ensuring proper segmentation, access control, and alignment with enterprise security standards.
• Support enterprise and plant-level network engineering projects, collaborating on implementations involving Fortinet, Palo Alto, Cisco, and wireless networking.
• Troubleshoot and resolve complex network connectivity and performance issues, focusing on high availability and security in both IT and limited OT environments.
• Assist with the integration of industrial control systems (SCADA, PLCs, HMIs) into secure network architectures, applying best practices for uptime and reliability.
• Apply cybersecurity frameworks such as the Purdue Model to guide secure network segmentation between IT and OT layers.
• Monitor and maintain network health through firmware updates, performance tuning, and proactive threat mitigation using Fortinet tools.
• Participate in the development of network security policies and procedures, ensuring alignment with NIST 800 series and industry best practices.
• Collaborate with cross-functional teams to support secure data exchange between OT systems and enterprise IT infrastructure.
• Stay up to date on Fortinet advancements, cybersecurity trends, and evolving best practices to continually strengthen the network environment.

Qualifications

What Will You Need

• Bachelor’s degree in Computer Science, Network Engineering, or a related technical field; advanced certifications are a plus.
• Minimum of 5 years of experience in enterprise network engineering, including hands-on management of secure, multi-site environments.
• Fortinet NSE4 certification or higher is required; must have demonstrated experience with complex Fortinet deployments, including firewalls, VPNs, and SD-WAN.
• Strong knowledge of routing, switching, and wireless networking, with practical experience using Fortinet, Palo Alto, and Cisco technologies.
• Experience designing and securing network architectures, including segmentation, access control, and threat mitigation.
• Familiarity with OT systems (SCADA, PLCs, DCS) and industrial networking concepts is preferred but not required.
• Solid understanding of cybersecurity frameworks and best practices, including NIST 800 series and the Purdue Model.
• Proven ability to troubleshoot and resolve advanced network issues in high-availability environments.
• Experience supporting IT/OT integration initiatives and managing secure connectivity between industrial and enterprise networks is a plus.
• Excellent collaboration and communication skills; able to work effectively with cross-functional teams including IT, engineering, and operations.
• Proven ability to brainstorm, develop, and implement innovative network solutions from concept to execution.
