Description
We are looking for an experienced Sr IT Administrator to support and strengthen enterprise infrastructure operations. This Long-term Contract opportunity is ideal for an experienced technology specialist who can guide systems architecture, maintain secure and reliable environments, and improve overall platform performance across network, server, virtualization, and cloud services. The role blends hands-on administration with technical leadership, requiring strong judgment, clear communication, and the ability to turn complex infrastructure needs into practical solutions.
Responsibilities:
Lead the planning and execution of infrastructure enhancements across network and server environments to improve resiliency, scalability, and uptime.
Administer and support core enterprise systems, including routers, switches, firewalls, Windows-based servers, virtual platforms, and end-user infrastructure.
Monitor system and network health using performance and traffic analysis tools, then recommend and implement improvements to resolve capacity issues and reduce bottlenecks.
Develop and maintain security-focused processes for patching, vulnerability response, certificate administration, and access control across critical systems.
Oversee backup, recovery, and business continuity practices, including regular testing to validate restoration readiness and failover effectiveness.
Manage voice and communication infrastructure, including VoIP-related components and supporting services tied to business operations.
Create automation scripts and operational tools to streamline deployment tasks, configuration management, maintenance routines, and backup activities.
Ensure infrastructure assets and software configurations remain aligned with internal standards, compliance expectations, and operational best practices.
Contribute to major platform upgrade or migration efforts when needed, ensuring minimal disruption and strong coordination across stakeholders.
Requirements
7+ years of experience in systems and network engineering, including at least 2 years serving in a lead, architectural, or senior technical capacity.
Advanced knowledge of enterprise networking concepts, routing technologies, firewall design, and modern security models such as zero-trust principles.
Strong experience with hyper-converged and traditional infrastructure platforms, including technologies such as Nutanix, VMware, VxRail, or vSAN environments.
Proven hands-on expertise with VMware, Microsoft 365, Active Directory, Microsoft Windows Server, and Windows 10 administration.
Proficiency in scripting or automation using tools such as PowerShell, Python, or Bash for systems management and operational efficiency.
Working knowledge of backup and disaster recovery strategies, certificate management, and infrastructure security administration.
Familiarity with enterprise hardware and platform technologies such as Dell and Citrix solutions.
Ability to communicate technical strategies clearly, translate infrastructure plans into actionable work, and earn required role-related certifications within established timeframes.
