10 - Technical Lead, IT Infrastructure 1Req ID: Region:AmericasCountry: CanadaState/Province: OntarioCity: Toronto Summary We are seeking a proactive and detail-oriented RDL Network Administrator to manage the day-to-day operations and administration of our global Research and Development Lab (RDL) networks. Reporting directly to the Lead Network Architect, you will be responsible for the run-and-maintain aspects of our isolated, air-gapped networks across multiple HPS Design Center locations (including San Jose, Richardson, Thailand, Shanghai, SongShan Lake, Penang, Chennai, and future sites). The ideal candidate will handle routing, switching, and firewall adjustments, manage user access, configure local jump hosts, and execute secure file transfers across air gaps. Since this environment operates under strict security isolation without typical enterprise automated management tools (e.G., Active Directory, automated endpoint agents), this role requires a hands-on, highly disciplined administrator who excels at executing manual and semi-automated workflows securely and consistently. Core Responsibilities 1. Daily Network Operations & Maintenance Infrastructure Monitoring: Monitor the health, performance, and uptime of all RDL hardware,



including Checkpoint 3980 Firewalls, SilverPeak SD-WAN appliances, Cisco Catalyst 9400/9200 switches, and Celestica DS2000/ES1500 switches. Configuration Management: Implement localized VLAN adjustments, IP address allocations, and switch port provisioning to isolate multi-tenant projects as directed by the Network Architect. Routine Maintenance: Execute hardware diagnostics, physical cabling checks, and firmware/OS updates across network and server appliances following strict maintenance window guidelines. 2. Identity & Secure Access Administration User Onboarding & Management: Provision local user accounts and role-based permissions directly on Linux-based jump hosts. Manage access credentials in a strict, decentralized non-Active Directory workplace. Remote Session Administration: Administer daily customer connections using CyberArk vPAM (Virtual Privileged Access Management) and internal user access using Zscaler ZTNA/Zscaler App Connectors. Security Audits: Review, audit, and clean up inactive user sessions and local accounts weekly to maintain strict security posture. 3. Data
