Senior Network & Security Specialist

Job Description

Responsibilities

• Lead the design and implementation of complex Fortinet and Cisco solutions (firewalls, switching, wireless, HA, SD-WAN), including Purdue Model–aligned network segmentation based on a clear understanding of application communication flows and IT/OT integration requirements.
• Design, implement, and support network security and NAC solutions, including policy design, enforcement, and ongoing optimization.
• Design and deploy secure authentication solutions for VPN, wireless, and NAC (e.g., RADIUS, 802.1X, certificate-based auth, MFA).
• Design and support hybrid network architectures, including cloud networking in platforms such as Microsoft Azure, with consideration for connectivity, security controls, and integration with on-premises and industrial environments.
• Serve as the technical lead for network projects, driving delivery from discovery and design through implementation, including greenfield deployments, network refreshes, security improvements, and architecture changes.
• Review designs and implementations produced by other team members.
• Provide technical mentorship and escalation support.
• Occasionally travel to client sites to perform detailed network discovery, assist with on-site implementation activities, and validate physical and logical designs during project delivery.
• Be personable, articulate, and clear in your communication – both written and spoken.

Qualifications & Experience

• Minimum of 8–10 years experience in mid-large enterprise/industrial/mining network design and delivery, including firewall, switching, wireless, and security architecture.
• Extensive hands-on experience with both Cisco and Fortinet enterprise environments. Expertise in Fortinet Fortigate firewalls is required. Experience with Palo Alto Networks firewalls is considered an advantage.
• Strong understanding of physical network connectivity and design considerations, including fiber and copper interfaces, SFP/GBIC selection and laser wavelength considerations, patch panel and termination design, ring and resilient topologies, LTE connectivity, and the application of technologies such as VXLAN where appropriate.
• Ability to read and critically review fiber network block diagrams is required; experience creating or updating such diagrams is considered an asset.
• Experience with centralized network and security management platforms, such as FortiManager, FortiAnalyzer, Cisco Catalyst Center, and NAC platforms such as Cisco ISE.
• You are confident in your expertise, comfortable making technical decisions, and able to clearly articulate trade-offs to both technical and non-technical stakeholders.
• Proficiency in ITSM tools such as incident and change management.
• A sense of humor. We’re building a team, in the truest sense.
• Tolerance and encouragement for people being and doing things differently – if you see only one way for the world to be, we’d very much prefer you respectfully decline this role
