Senior System Administrator

Senior IT System AdministratorThe purpose of this document is to define the expert-level technical criteria, structural engineering responsibilities, and leadership expectations for the Senior IT System Administrator role at Foxconn Industrial Internet. The Senior System Administrator is responsible for designing, optimizing, and securing the organization's global enterprise server infrastructure, data storage, virtualization layers, and cloud ecosystems. Serving as the Tier-3 escalation point for all enterprise system issues, this role leads complex datacenter migrations, cloud-native transformations, and ensures business continuity across all production-critical systems.Core ResponsibilitiesArchitecture & Infrastructure Design: Lead the design, sizing, implementation, and lifecycle management of enterprise server infrastructure, high-performance storage arrays (SAN/NAS), hyper-converged systems (HCI), and hybrid cloud environments. Tier-3 Escalation & Problem Management: Serve as the ultimate internal technical authority for complex server operating system anomalies, Active Directory forest-level issues, virtualization deadlocks, and critical storage failures. Lead root-cause analysis (RCA) and emergency recovery during high-priority (P1/P0) system outages. Infrastructure as Code (IaC) & Automation: Drive the automation strategy for system provisioning, configuration management, and patching. Design, build, and maintain automation pipelines to eliminate manual overhead and enforce standard system baselines. Cloud & Hybrid Integration: Architect and manage enterprise workloads across public cloud platforms (AWS, Azure) and on-premises datacenters. Lead migrations from legacy infrastructures to highly redundant, cloud-native or hybrid models. Business Continuity & Disaster Recovery (BC/DR): Design, implement, and periodically test enterprise-grade disaster recovery architectures, automated backup strategies, and multi-site replication policies to guarantee strict Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO). Security hardening & Compliance: Oversee system security hardening in alignment with international standards (such as ISO 27001 or NIST). Manage enterprise identity services, Role-Based Access Control (RBAC), and patch compliance matrices across thousands of endpoints. Capacity Planning & Budget Input: Conduct technical audits and deep capacity analysis of compute, memory, and storage footprints. Provide data-driven recommendations and technical inputs for annual IT capital expenditure (CapEx) and operational expenditure (OpEx) budgeting. Leadership & Mentorship: Establish corporate system engineering standards and approve technical Standard Operating Procedures (SOPs). Actively mentor and cross-train junior system administrators and network engineers to elevate overall team capabilities.Technical QualificationsEducation and CertificationA Bachelor's or Master's degree in Computer Science, Computer Engineering, Management Information Systems, or a strictly related field is required. Active expert-level certifications are highly preferred, such as MCSE (Core Infrastructure), VMware VCP/VCAP (DCV), Red Hat Certified Engineer (RHCE), or Professional Cloud Architect certifications (AWS Professional / Azure Solutions Architect Expert).Enterprise Operating Systems & Directory ServicesDeep expertise in managing enterprise Active Directory Domain Services (AD DS) in multi-domain/multi-forest environments, including Group Policy (GPO) architecture, trust relationships, Active Directory Certificate Services (AD CS), and seamless synchronization with Azure AD / Entra ID. Expert-level administration of enterprise Linux distributions (RHEL, Ubuntu Server). In-depth knowledge of Windows Server (2019/2022) clustering, Storage Spaces Direct (S2D), and advanced troubleshooting of core network services (DNS, DHCP, NPS) at scale.Virtualization, Storage & Cloud ArchitectureExpert-level configuration, management, and troubleshooting of VMware vSphere suites (vCenter, ESXi, vSAN, NSX). Proven experience deploying and maintaining high-availability (HA) clusters, Distributed Resource Scheduler (DRS), and live migration mechanics. Advanced management of enterprise-grade storage hardware (e.g., Dell EMC, NetApp, Pure Storage) utilizing Fibre Channel (FC), iSCSI, and NFS protocols. Designing robust multi-pathing (MPIO) and fabric configurations. Foundational-to-advanced experience with Docker container environments and orchestration platforms like Kubernetes (K8s) or Red Hat OpenShift in a production setting.DevOps, Automation & ToolingMastery of configuration management and deployment automation tools such as Ansible, Terraform, Puppet, or Chef. High proficiency in building robust scripts using PowerShell or Python to query APIs, automate auditing, and manipulate complex data structures. Design and optimization of centralized monitoring systems (e.g., Zabbix, Prometheus/Grafana, Datadog) with customized alerting thresholds, log aggregation, and synthetic transactions monitoring.Physical and Operational RequirementsFlexibility to lead high-risk infrastructure upgrades during scheduled weekend maintenance windows. Must participate in a Tier-3 on-call rotation to support 24/7/365 production facility uptime. Superior understanding of modern datacenter physics, including hot/cold aisle containment, power distribution unit (PDU) calculations, and thermal environmental optimization.Security & ComplianceDue to unrestricted privileged access (Domain Admin / Root) to critical intellectual property and industrial automation data, execution of a comprehensive NDA and IP agreement is mandatory. Must pass an extensive, executive-level pre-employment background and professional credential check.
