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, Song Shan 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.

• Infrastructure Monitoring:
  Monitor the health, performance, and uptime of all RDL hardware, including Checkpoint 3980 Firewalls, Silver Peak 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.

• 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 environment.
• Remote Session Administration:
  Administer daily customer connections using Cyber Ark 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.

• Multi‑Tier Sync Execution:
  Execute and monitor the secure transfer of "transfer bundles" containing OS packages (Rocky Linux, Ubuntu, CentOS, etc.), drivers, and software libraries across the air gap.
• Local Repo Hosting:
  Ensure local web repositories (Apache/Nginx hosted at /var/(Use the "Apply for this Job" box below).) are operational, indexed, and accessible to local lab systems.
• Integrity Validation:
  Verify the cryptographic hashes (SHA‑256 checksums) of all data packages moving from the Global Repository Server to the RDL Local Repository Server.

• End‑User Support:
  Act as the primary technical point of contact for HPS design engineers needing network troubleshooting, IP conflicts resolved, or new package requests.
• Ticketing Operations:
  Process, update, and resolve secure lab support tickets in accordance with established Service Level Agreements (SLAs).
• Escalation Point:
  Identify complex network issues or design deviation requests and escalate them directly to the Lead Network Architect.

• Software Auditing:
  Conduct regular logical audits of systems within the RDL to ensure strictly banned corporate agents (e.g., Crowd Strike, Threat Locker, Big Fix, Service Now Agents, Clear Pass NAC) are not installed.
• Asset Tracking:
  Maintain a flawless inventory of all HPS‑owned assets inside the RDL physical rooms, including servers, switches, wireless access points (Aruba 755), and connected lab machines.

• Network & Security Hardware:
  Practical experience configuring and troubleshooting Cisco switches (Catalyst/Nexus) and administering Checkpoint Firewalls (defining security rules, NAT, and logs).
• Linux System Administration:
