Senior IT System Administrator Purpose and Scope

1.1. Objective:
The 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.

1.3. Mission:
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.

• Architecture & 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 (Cap Ex) 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.

• Academic Background: A Bachelor’s or Master’s degree in Computer Science, Computer Engineering, Management Information Systems, or a strictly related field is required.
• Professional Credentials:
  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).

• Advanced Active Directory & IAM:
  Deep 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 .
• Linux/Unix Expertise:
  Expert-level administration of enterprise Linux distributions (RHEL, Ubuntu Server). Advanced mastery of performance tuning, kernel parameters optimization, systemd troubleshooting, and deep shell scripting (Bash).
• Windows Server Mastery:
  In‑depth knowledge of Windows Server (2019/2022) clustering, Storage Spaces Direct (S2D), and advanced troubleshooting of core network…
