- Perform regular system optimization and maintenance activities including patching, upgrades, configuration management, and performance tuning.
- Provide tier-3 escalation support and troubleshooting, resolving complex infrastructure, hardware, software, and operating system issues.
- Participate in after-hours on-call rotation and works non-standard hours as required, with accountability for ensuring systems are architected to be stable, supportable, and recoverable.

Systems Architecture & Infrastructure Design

- Own the system architecture for assigned infrastructure domains, including defining standards, reference architectures, design patterns, and technical roadmaps.
- Design, implement, and support systems that meet the demands of a 24x7, mission-critical, multi-site operation, with emphasis on high availability, resiliency, fault tolerance, and recoverability.
- Lead requirements gathering, architecture, technical design, and deployment of new systems and major enhancements in collaboration with the System Manager, IT peers, and business stakeholders.
- Act as technical lead and systems architect on small and large IT initiatives, providing design authority and implementation guidance.
- Define and implement standardized architectures and configurations across multiple sites to ensure consistency, reliability, and simplified operational support.

Security, Resiliency & Business Continuity:

- Ensure monitoring, alerting, backup, disaster recovery, and security controls are designed into all solutions and aligned with operational and business continuity requirements.
- Participate in disaster recovery testing exercises and contribute to business continuity planning for business-critical systems.
- Analyze recurring incidents and outages to identify architectural or design improvements and lead remediation efforts to reduce future operational risk.
- Identify opportunities for continuous improvement and modernization, proposing solutions that improve reliability, security, and operational efficiency.

Technical Leadership & Collaboration

- Provide technical leadership and guidance across infrastructure projects, operational initiatives, and modernization efforts.
- Mentor and support System Administrators, promoting best practices, knowledge sharing, and consistent engineering standards.
- Collaborate with IT peers, leadership, vendors, and business stakeholders to deliver reliable, scalable, and secure infrastructure solutions

Change Management & Governance

- Submit and manage change requests, including implementation, testing, communication, and back-out planning, following ITIL best practices.
- Lead change management and CAB processes, providing technical and architectural review of proposed changes.
- Ensure infrastructure solutions align with enterprise standards, operational requirements, and governance frameworks.
- Create and maintain accurate system, architecture, and operational documentation and knowledge base articles.

Educational and Functional Requirements:

• 7–10+ years of progressive experience in system administration and enterprise infrastructure roles, including demonstrated responsibility for system design and architecture.
• Demonstrated experience in systems architecture, technical design, and solution implementation.
• Proven experience and advanced working knowledge of a majority of the following in an enterprise environment:
o Virtualization platforms such as VMware ESXi and Nutanix AHV
o Microsoft Windows Server operating systems
o Enterprise server hardware (e.g., Dell PowerEdge, Lenovo ThinkSystem, Nutanix HCI)
o Microsoft Active Directory services (DNS, DHCP, Group Policy)
o Cloud platforms such as Microsoft Azure, AWS, or Google Cloud
o Azure AD, Office 365, and identity technologies (SSO, MFA, Conditional Access)
o Disaster recovery and replication technologies (e.g., Zerto, Nutanix Metro)
o Citrix Virtual Apps and Desktops
o PowerShell scripting and automation tools
o Endpoint management platforms (MECM, Intune)
o Infrastructure monitoring tools (e.g., SolarWinds, Dynatrace, Datadog)

• Industry certifications (Microsoft, Azure/AWS, Citrix, Nutanix, ITIL) are considered an asset.
