- Experience administering at least one major cloud platform: AWS, Azure, or GCP.
- Proficiency in scripting and automation with PowerShell, Bash, or Python.
- Working knowledge of networking fundamentals, including TCP/IP, VLANs, firewalls, VPN, and load balancing.
- Proven experience with backup, recovery, and disaster recovery planning.
- Clear written and verbal communication skills, including the ability to explain technical issues to non-technical colleagues.
- Bachelor's degree in a related field or equivalent practical experience.
Responsibilities
- Administer, patch, and maintain Windows and Linux servers across on-premises, virtualized, and cloud environments.
- Manage virtualization and hyperconverged infrastructure, including capacity planning, performance tuning, and lifecycle upgrades.
- Own identity and access management, including Active Directory, Entra ID/Azure AD, SSO, and MFA, and enforce least-privilege practices.
- Design and maintain backup, disaster recovery, and business continuity plans, and test them regularly.
- Monitor system health, respond to incidents, lead root-cause analysis, and prevent recurring issues.
- Automate repetitive tasks and configuration using scripting or infrastructure-as-code tools.
- Partner with Security on vulnerability remediation, hardening, audit evidence, and compliance requirements.
- Lead infrastructure projects such as migrations, platform upgrades, and new tool rollouts from scoping through delivery.
- Maintain documentation, runbooks, and network and system diagrams.
- Mentor junior administrators and serve as the senior escalation point for the IT team.
- Participate in a shared on-call rotation and occasional after-hours maintenance windows.
