Position Summary

The Network, Infrastructure & Cybersecurity Specialist is responsible for maintaining, supporting, securing, monitoring, and continuously improving network and connectivity infrastructure across corporate offices and multiple retail locations.

 

This position serves as the primary technical owner for LAN/WAN connectivity, SD-WAN, switches, firewalls, wireless infrastructure, internet circuits, network monitoring, infrastructure documentation, and network-focused cybersecurity.

 

The role requires strong technical ownership, proactive monitoring, structured troubleshooting, accurate documentation, vendor coordination, and flexibility to support a multi-location retail environment where technology availability is critical to daily business operations.

 

This is a specialized infrastructure position rather than a traditional Help Desk role.

Monitoring & Incident Management (15%)

· Proactively monitor network infrastructure and connectivity.

· Take ownership of network and infrastructure incidents from identification through resolution.

· Troubleshoot network incidents using a structured root-cause approach.

· Coordinate with vendors and service providers when external escalation is required.

· Maintain internal ownership of an incident even when a third-party provider is involved.

· Provide timely and clear communication during network outages and major incidents.

· Communicate business impact, escalation status, progress, and expected next actions.

· Document incident findings, root causes, resolutions, and preventive actions.

· Identify recurring patterns and recommend improvements to reduce future incidents.

· Ensure incidents and infrastructure activities are properly documented through established IT ticketing processes.

New Stores, Remodels & Infrastructure Deployments (10%)

This position will play a key technical role in supporting company growth and new locations.

· Document the completed network environment, configurations, equipment, circuits, and topology.

· Participate in SD-WAN migrations, network modernization, equipment refreshes, and other infrastructure initiatives.

On-Call & Critical Incident Support (5%)

Participation in the IT department's on-call process is an expectation of this position.

· Document on-call incidents, actions taken, escalation history, and final resolutions.

· Participate in post-incident reviews for significant outages when appropriate.

· Maintain sufficient documentation and cross-training so backup personnel can assist when necessary.

After-Hours, Weekend & Overnight Work (5%)

Because technology changes and infrastructure maintenance cannot always be safely performed while retail locations are actively operating, this position requires scheduling flexibility.

· Be available for planned after-hours infrastructure maintenance.

· Be willing to work evenings when infrastructure changes cannot be safely completed during normal business hours.

· Participate in weekend maintenance and technology deployments when required.

· Be willing to perform overnight work when network migrations, infrastructure changes, store deployments, or business requirements require it.

· Support critical store openings or major technology deployments outside normal business hours when necessary.

· Respond to critical network or infrastructure incidents according to the established on-call and escalation process.

Due to the operational nature of a multi-location retail environment, this position requires flexibility to participate in an on-call rotation and to work evenings, weekends, overnight maintenance windows, emergency incidents, and store-opening activities when business or infrastructure requirements demand it.

Travel & Field Support (5%)

· Travel regularly between corporate offices and retail locations as part of normal responsibilities.

· Travel to locations for network troubleshooting, installations, upgrades, infrastructure assessments, and store openings.

· Provide onsite technical support when network or infrastructure issues cannot be effectively resolved remotely.

· Cross-train designated IT personnel to provide backup coverage.

Ownership & Accountability (5%)

This position requires a strong sense of technical ownership.

· Serve as the primary technical point of ownership for network and connectivity infrastructure.

· Take ownership of assigned incidents from identification through resolution.

· Maintain ownership when an ISP, vendor, or external service provider must participate in resolution.

· Proactively identify infrastructure risks, weaknesses, and improvement opportunities.

· Research and recommend infrastructure improvements.

· Provide technical recommendations based on reliability, security, scalability, cost awareness, and business requirements.

· Communicate proactively during outages, projects, maintenance activities, and critical incidents.

· Follow established ticketing, documentation, security, and change-management procedures.

· Properly plan and document infrastructure changes before implementation.

· Complete appropriate post-incident documentation following significant outages.

· Identify preventive actions after recurring or major incidents.

· Build sufficient internal documentation and backup knowledge to reduce single-person dependency.

· Continuously develop technical knowledge in networking, infrastructure, and cybersecurity.

The expectation of ownership is simple:

Own the issue, investigate it, engage the appropriate resources, communicate its status, drive it toward resolution, document the outcome, and identify opportunities to prevent recurrence.
