• Manage enterprise wireless security and authentication technologies, including WPA3-Enterprise, RADIUS, and ISE.
• Configure and optimize Wireless LAN Controllers (WLCs), DCIM platforms, and Power over Ethernet (PoE) capacity requirements.
• Lead root cause analysis (RCA) for major incidents and outages, implementing corrective actions to improve infrastructure reliability.
• Develop and maintain standard operating procedures (SOPs), technical documentation, and environmental health and safety (EHS) standards.
• Coordinate technical assignments, delegate tasks, monitor progress, and communicate project status during kickoff meetings, incident reviews, and stakeholder discussions.
• Support advanced infrastructure technologies, including liquid-cooled AI/ML computing clusters.
• Apply established L1 and L2 operational practices while providing technical guidance and leadership to field teams.

Required Experience/Skills for the Field Technician III:

• 5+ years of relevant experience in data center infrastructure, network integration, field engineering, or telecommunications environments.
• Advanced knowledge of data center infrastructure, including power distribution, high-density fiber architecture, hardware deployment, and site expansion activities.
• Expertise with LC, SC, MPO, and MTP fiber connectors and associated cabling standards.
• Strong hands-on experience with fiber cleaning, inspection, testing, light-level analysis, polarity, bend radius, and troubleshooting signal loss.
• Demonstrated ability to diagnose Layer 1 and Layer 2 network issues, including VLANs, LACP, and Spanning Tree.
• Experience with server hardware repairs, motherboard swaps, DIMM troubleshooting, and remote management technologies such as iDRAC and iLO.
• Strong understanding of wireless RF principles, including SNR, RSSI, interference, access point placement, and high-density wireless design.
• Experience with enterprise wireless security, WPA3-Enterprise, RADIUS/ISE, WLC configuration, and active site surveys.
• Proficiency with Data Center Infrastructure Management (DCIM) platforms and PoE capacity planning.
• Proven ability to conduct root cause analysis, resolve major incidents, and implement lasting corrective actions.
• Strong technical writing, documentation, communication, and team coordination skills.
• Ability to manage multiple assignments, delegate tasks, track progress, and communicate project updates to stakeholders.
• Demonstrated knowledge of standard operating procedures, safety practices, and infrastructure operational standards.

Preferred Experience/Skills for the Field Technician III:

• Experience supporting liquid-cooled AI/ML clusters or other advanced high-performance computing environments.
• Background in large-scale data center migrations, decommissions, and infrastructure expansions.
• Experience managing vendor service-level agreements (SLAs) and coordinating infrastructure projects with significant budgets.
• Familiarity with enterprise-scale wireless deployments in warehouses, corporate offices, and other high-density environments.
• Experience creating technical standards, operational playbooks, and safety procedures for field engineering teams.
• Demonstrated leadership in incident management, technical project coordination, and cross-functional collaboration.

Education Requirements:

• Relevant technical education, certifications, or equivalent hands-on experience in data center infrastructure, networking, telecommunications, or systems engineering.
• Industry certifications in networking, fiber optics, data center operations, or wireless technologies are preferred.

Benefits:

• Atrium Care Package available, upon eligibility (including healthcare plans, discount programs, and paid time off).
