Job Summary:
Working under limited supervision, the IT System Administrator III is a senior-level technical role responsible for managing, optimizing, and securing the organization's infrastructure. This position provides advanced support, leads system implementations, and acts as an escalation point for complex issues across servers, networks, applications, and cloud environments.
To perform this job successfully, an individual must be able to perform each essential duty satisfactorily. The requirements listed below are representative of the knowledge, skill, and/or ability required. Reasonable accommodations may be made to enable individuals with disabilities to perform the essential functions.
Responsibilities:
Administer, maintain, and optimize Windows and/or Linux server environments
Manage infrastructure services including Active Directory, DNS, DHCP, Group Policy, identity and access management, and directory synchronization
Oversee enterprise storage, virtualization platforms (VMware/Hyper-V), and backup/DR solutions
Implement and maintain security standards, patching, hardening, and monitoring across all systems
Provide Tier III incident and problem resolution for escalated infrastructure issues
Lead system upgrades, migrations, integrations, and infrastructure projects
Manage cloud environments such as Microsoft 365, Azure, or AWS
Develop and maintain technical documentation, diagrams, SOPs, and runbooks
Collaborate with cross-functional teams including Networking, Security, Helpdesk, and Application Support
Perform capacity planning and make recommendations for system improvements
Required Education & Experience:
7+ years of hands-on experience as a system administrator or similar role, required
Advanced knowledge of Windows Server and/or Linux systems
Strong experience with virtualization (VMware, Hyper-V)
Familiarity with cloud platforms (Azure, AWS, Microsoft 365)
Experience with PowerShell or similar automation/scripting tools
Strong understanding of networking fundamentals (TCP/IP, routing, firewalls, VLANs)
Experience with endpoint management platforms (Intune, SCCM, Jamf, etc.)
Knowledge of security best practices, compliance standards, and threat mitigation
Excellent troubleshooting, documentation, and communication skills
Competencies:
Strong analytical and problem-solving abilities
Ability to work independently and lead technical initiatives
Effective communication with both technical and non-technical stakeholders
High attention to detail and commitment to system reliability and security
Essential Traits:
Collaboration, Trust & Engagement: Builds strong working relationships with Networking, Security, Helpdesk, and Application Support teams; communicates clearly during migrations, upgrades, and Tier III incidents so cross-functional partners stay informed; earns trust as the go-to escalation point for complex infrastructure issues.
Customer Focus & Impact: Understands how server, identity, storage, and cloud reliability affect end users and business units; resolves Tier III incidents and problems in ways that minimize disruption and rebuild confidence in IT; delivers infrastructure projects and migrations that create lasting value rather than short-term fixes.
Results & Accountable: Takes ownership of enterprise infrastructure (AD, DNS, DHCP, GPO, storage, virtualization, backup/DR) with a bias toward action; drives patching, hardening, and monitoring on schedule; leads upgrades and migrations to completion and holds self accountable for system stability and security posture.
Business & Financial Insights: Applies sound judgment to capacity planning, licensing (e.g., M365, Azure, AWS), and infrastructure investment recommendations; balances cost, performance, and risk when proposing system or platform improvements; understands the business impact of downtime, security gaps, or under-provisioned capacity.
Innovation & Courage: Proactively identifies opportunities to modernize, automate, or consolidate infrastructure while operating within ITAR and export-control boundaries (e.g., data segregation, access restrictions on regulated systems); has the courage to enforce compliance-driven security standards even when they slow down convenience or push back on non-compliant requests; challenges outdated configurations or manual processes, and adapts confidently as environments evolve toward hybrid/cloud models without compromising controlled-technical-data safeguards; documents changes clearly (SOPs, runbooks, diagrams) to keep improvements sustainable and audit-ready.
Physical Requirements:
Prolonged periods sitting at a desk while working on a computer
Ability to lift up to 15 pounds as required
Must be able to quickly navigate manufacturing areas
Ability to stand, bend, crawl, stretch, lay, and squat for equipment maintenance
