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).\nThe 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.\nCore Responsibilities\n1. Daily Network Operations & Maintenance\nInfrastructure 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.\nConfiguration Management: Implement localized VLAN adjustments, IP address allocations, and switch port provisioning to isolate multi-tenant projects as directed by the Network Architect.\nRoutine Maintenance: Execute hardware diagnostics, physical cabling checks, and firmware/OS updates across network and server appliances following strict maintenance window guidelines.\n2. Identity & Secure Access Administration\nUser 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.\nRemote Session Administration: Administer daily customer connections using CyberArk vPAM (Virtual Privileged Access Management) and internal user access using Zscaler ZTNA/Zscaler App Connectors.\nSecurity Audits: Review, audit, and clean up inactive user sessions and local accounts weekly to maintain strict security posture.\n3. Data Transfer & Repository Sync Operations\nMulti-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.\nLocal Repo Hosting: Ensure local web repositories (Apache/Nginx hosted at /var/www/html/repo/) are operational, indexed, and accessible to local lab systems.\nIntegrity Validation: Verify the cryptographic hashes (SHA-256 checksums) of all data packages moving from the Global Repository Server to the RDL Local Repository Server.\n4. Support Ticket Resolution & SLA Adherence\nEnd-User Support: Act as the primary technical point of contact for HPS design engineers needing network troubleshooting, IP conflicts resolved, or new package requests.\nTicketing Operations: Process, update, and resolve secure lab support tickets in accordance with established Service Level Agreements (SLAs).\nEscalation Point: Identify complex network issues or design deviation requests and escalate them directly to the Lead Network Architect.\n5. Compliance & Clean Environment Enforcement\nSoftware Auditing: Conduct regular logical audits of systems within the RDL to ensure strictly banned corporate agents (e.g., CrowdStrike, Threat Locker, Big Fix, ServiceNow Agents, ClearPass NAC) are not installed.\nAsset 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.\nKnowledge/Skills/Competencies\nRequired Technical Skills:\nNetwork & Security Hardware: Practical experience configuring and troubleshooting Cisco switches (Catalyst/Nexus) and administering Checkpoint Firewalls (defining security rules, NAT, and logs).\nLinux System Administration: Mid-to-senior level competency in Linux (Rocky, CentOS, Ubuntu)-specifically user management, bash scripting, basic routing, and running local web servers (Apache/Nginx).\nAccess Tools: Experience working with remote access tools such as Zscaler ZTNA / App Connectors and Privilege Access Management solutions (specifically CyberArk).\nVirtualization Basics: Solid experience administering VMs, clusters, and virtual switches within VMware vSphere or Microsoft Hyper-V environments.\nAir-Gap Protocols: Working knowledge of secure file transfer protocols (SFTP, SCP, rsync) and security scanning methodologies.Preferred \nCertifications:\nCCNA (Cisco Certified Network Associate)\nCheck Point Certified Security Administrator (CCSA)\nCompTIA Security+ or Linux+\nCyberArk Certified Trustee or Defender\nSoft Skills & Working Style:\nHigh Operational Discipline: Ability to strictly adhere to Standard Operating Procedures (SOPs) without cutting corners, even during urgent troubleshooting.\nExcellent Communicator: Strong written and verbal communication skills, necessary for translating technical issues to designers and coordinating with corporate security teams.\nMulti-Tasker: Capable of balancing ticket requests from multiple global labs concurrently while maintaining accurate records.\nPhysical Demands\nDuties of this position are performed in a normal office environment.\n\nDuties may require extended periods of sitting and sustained visual concentration on a computer monitor or on numbers and other detailed data. Repetitive manual movements (e.g., data entry, using a computer mouse, using a calculator, etc.) are frequently required.\n\nEducation & Experience\nBachelor’s degree in Network Administration, Information Technology, Computer Science, or equivalent hands-on experience.\n10+ years of experience in network administration or system administration, preferably managing secure, segmented, or laboratory networks.\nNotes\nThis job description is not intended to be an exhaustive list of all duties and responsibilities of the position.
