Infrastructure Systems Administrator (Windows/Linux) (Systems Engineer)

Role Overview

Responsible for the reliable management, maintenance, and optimization of SFM Sports venues’ IT infrastructure including Windows servers, Red Hat-based Linux servers, cloud resources, and hyperconverged infrastructure (HCI) platforms such as Nutanix and VMware vSAN.

This role ensures high availability, security, and performance across all systems by proactively monitoring, troubleshooting, and implementing best practices in both on-premises and cloud environments. The administrator supports business continuity, scalability, and operational excellence, and plays a key part in enabling seamless IT operations for all Sports venues.

General System Management

• Monitor server performance, capacity, and resource utilization using enterprise monitoring tools (e.g., Zabbix, Grafana, Nagios, SolarWinds).
• Perform regular system backups, disaster recovery drills, and data integrity checks.
• Apply security patches, update, and conduct vulnerability assessments across all infrastructure components.
• Optimize system configurations for efficiency, including hardware provisioning and virtualization management (e.g., VMware, Nutanix).
• Maintain comprehensive documentation for system configurations, procedures, and incident responses.

Cloud Infrastructure Management

• Configure and monitor cloud resources (e.g., virtual machines, storage, networking) across public and hybrid environments.
• Assist in hybrid cloud integrations (e.g., directory synchronization, identity-aware proxies) for seamless on-premises to cloud transitions.
• Perform cost optimization reviews and scaling adjustments for cloud workloads.
• Support troubleshooting and resolution of cloud-specific issues, collaborating with cloud architects for advanced deployments.
• Ensure compliance with cloud security and governance policies.

Windows and Linux Server Operations

• Administer Windows Server Environments (installation, configuration, clustering, failover management).
• Manage Linux servers, with a strong emphasis on Red Hat-based distributions (e.g., RHEL, CentOS, Rocky Linux), including shell scripting, package management (yum/dnf), and performance tuning.
• Enforce server hardening and firewall rules, ensuring compliance with CIS benchmarks.
• Automate server provisioning and maintenance using PowerShell (Windows) and Ansible/Bash (Linux).
• Conduct root cause analysis and remediation for server-related incidents.

Active Directory Management

• Manage user and group policies, permissions, and authentication via Group Policy Objects (GPOs) and Azure AD hybrid setups.
• Monitor Active Directory health using tools like ADREPLSTATUS; perform regular security and compliance audits.
• Integrate Active Directory with other systems for cross-platform identity management.
• Implement and maintain least privilege access principles and periodic access reviews.
• Support directory migrations, upgrades, and federation services as required.

HCI Environment

• Cluster Deployment: Configure nodes and storage pools for hyper-converged infrastructure.
• Resource Optimization: Balance workloads across nodes for performance.
• High Availability: Implement failover clustering and test disaster recovery scenarios.
• Firmware Updates: Apply updates to HCI hardware and hypervisor software.
• Monitoring: Use vendor tools (e.g., Nutanix Prism, VMware vSAN) for health checks.

Experience

• 5 years of hands-on experience in IT infrastructure administration, with at least 2 years focused on Windows Server and Linux environments.
• Proven experience managing hybrid IT setups, including public and hybrid cloud environments.

Education

• Bachelor’s degree in Computer Science, Information Technology, or equivalent experience.
• Microsoft and Linux Certifications.
• Hyperconverged Infra Certifications (Dell, Nutanix etc.).
• VMware/Nutanix Certifications.
• Cloud certifications.

Required Skillsets

• In-depth proficiency in Windows Server administration, including Active Directory, Group Policy, PowerShell automation, and server clustering.
• Advanced Linux server management skills, with a strong focus on Red Hat-based distributions (installation, configuration, patching, performance tuning, security hardening, and troubleshooting).
• Experience with virtualization platforms, especially VMware and Nutanix (deployment, management, and optimization).
• Hands-on experience configuring and managing cloud resources (virtual machines, storage, networking) in public and hybrid cloud environments.
• Expertise in enterprise backup, disaster recovery, and business continuity planning.
• Ability to automate server provisioning, configuration management, and monitoring using tools such as Ansible, Bash, and PowerShell.
• Strong documentation, communication, and collaboration skills.
• Ability to analyze and resolve complex infrastructure issues, conduct root cause analysis, and implement preventive measures.
