Job Description:

What you'll do Scope of Role: You will be the primary technical lead for the LAN and Wireless infrastructure supporting 1,000 FTEs across 70 sites. This portfolio includes a diverse mix of Corporate Offices, Distribution Centers with retail components, and large-scale Warehouses. Multi-Environment Site Evaluations: Visit and audit a variety of settings, from high-density corporate offices to industrial warehouses and retail-integrated distribution centers. Determine what equipment should be retained, what requires replacement, and what requires configuration optimization. Standardization and Remediation: Bring inherited or non-standard network closets up to corporate standards. This includes firmware alignment, VLAN cleanup, and improving physical rack hygiene in diverse physical environments. New Site Launches: Lead the end-to-end networking for new location openings, from initial site surveys and hardware list creation to final go-live and testing. Performance Tuning: Optimize wireless coverage and Layer 2/3 switching to ensure 1,000 users have stable connectivity, whether they are in a carpeted office or a high-interference warehouse floor. Escalated Support: Serve as the on-site expert for complex connectivity issues that remote teams cannot resolve, spanning all facility types. Travel Component: The first 6 months will require more travel to touch each location for audits, new builds, and optimizations. Once the baseline is established, travel reduces to 20% or less with a focus on Corporate HQ and remote management. What we're looking for Versatile Engineering Skills: You are as comfortable troubleshooting a core switch in a data closet as you are mapping out access point placement in a 100,000 square foot warehouse. Technical Stack: Proficiency with Juniper (Junos CLI for VLANs, trunking, and L3 routing) and Ubiquiti UniFi (Controller management, AP adoption, and RF channel planning). Enterprise Perspective: Experience managing a distributed footprint of 70 sites. You understand the unique challenges of industrial networking, such as RF interference in warehouses and high-uptime requirements for retail/distribution. Pragmatism: You evaluate the actual performance of existing hardware and prioritize stability over simply replacing gear for the sake of it. Multi-Locations: Proven experience supporting multiple locations and environments ranging from Corporate HQ to field sites. Hardware: Juniper EX/QFX, Ubiquity/UniFi Wireless and Switching.
