• Data Center Technologies: Mastery of data center switching fabrics, Cisco Nexus switches (NX-OS), vPC (Virtual Port Channels), VXLAN, and Quality of Service (QoS) design for traffic prioritization.
• Next-Generation Firewalls (NGFW): Expert-level configuration and lifecycle management of enterprise-grade firewalls, specifically Fortigate and Palo Alto clusters. Advanced implementation of High Availability (HA), Intrusion Prevention Systems (IPS), SSL Inspection, and Deep Packet Inspection (DPI).
• Cryptography & PKI Infrastructure: Thorough understanding of cryptographic protocols. Experience implementing highly secure Site-to-Site IPsec VPNs and remote-access SSL VPNs utilizing advanced symmetric/asymmetric algorithms (AES, RSA, ECC). Strong command of Public Key Infrastructure (PKI) concepts, including certificate lifecycle, Certificate Authorities, and handling revocation lists (CRLs/OCSP).
• Wireless Infrastructure: Expertise in designing, surveying, and tuning high-density enterprise wireless networks. Advanced management of centralized Wireless LAN Controllers (WLCs), Wi-Fi 6/6E/7 deployments, and secure authentication mechanism integration (802.1X, RADIUS, TACACS+).
• Network Programmability: Hands-on experience using Python, Ansible, or Terraform for network automation, configuration backup, and API-driven infrastructure management.
• Expert Protocol Analysis: Expert capability in using Wireshark, tcpdump, and network flow monitoring tools to dissect multi-layered protocol anomalies, performance bottlenecks, and security breaches at the packet level.
• Ability to participate in a senior-level on-call rotation for critical infrastructure emergencies.
• Flexibility to perform high-risk network maintenance during non-business hours/weekends.
• Capable of supervising physical datacenter layouts, ensuring structural cabling standards (Fiber and Copper) meet strict structural and environmental requirements.
• Execution of a strict, comprehensive NDA and IP protection agreement is mandatory.
• Must pass a stringent, comprehensive executive criminal and professional background verification.

Nice To Haves

• Active expert-level certifications are highly preferred, such as CCIE (Enterprise Infrastructure/Data Center), CCNP Enterprise, Fortinet NSE 7/8, or equivalent proven industry experience.

Responsibilities

• Lead the architectural design, engineering, and long-term capacity planning of corporate data centers, manufacturing plant networks, global WAN/SD-WAN structures, and enterprise campus environments.
• Act as the highest internal technical authority for complex routing, switching, wireless, and network security incidents. Direct emergency troubleshooting efforts during high-priority (P1/P0) network outages.
• Serve as the technical lead or Project Manager for major infrastructure initiatives, including data center migrations, cloud integrations, and core hardware refreshes. Ensure projects are delivered within scope, on schedule, and with zero business disruption.
• Champion network automation initiatives. Develop scripts and utilize orchestration tools to automate repetitive tasks, configuration provisioning, compliance auditing, and mass firmware deployments.
• Design and enforce enterprise-wide network security baselines, zero-trust architectures, and segmentation strategies. Ensure network infrastructure complies with global standards (e.g., ISO 27001, NIST) and Foxconn internal security policies.
• Oversee relationships with telecommunication carriers, internet service providers (ISPs), and core hardware vendors (Cisco, Fortinet, Palo Alto). Lead negotiations for service contracts, technical support agreements, and hardware procurements.
• Provide technical guidance, training, and mentorship to junior network administrators and helpdesk staff. Establish engineering standards, best practices, and approve comprehensive Standard Operating Procedures (SOPs).
