About The Position

Walton Global is seeking an experienced, hands-on Cybersecurity and Systems Administrator to lead day-to-day cybersecurity operations while also supporting Windows Server, Microsoft Azure, Microsoft 365, Entra ID, Active Directory, and related infrastructure when needed. The primary focus of this role is cybersecurity, including incident response, vulnerability management, security monitoring, policy enforcement, endpoint protection, and risk reduction. The successful candidate must also be capable of stepping in to support core systems administration responsibilities during high-volume periods, project demands, or when the Systems Administrator is unavailable. This is not a junior or entry-level position; it requires strong independent judgment, technical experience, and the ability to operate effectively in a mature enterprise IT environment.

Requirements

Minimum 4–6+ years of progressive experience across cybersecurity, Windows systems administration, Microsoft Azure, Microsoft 365, and enterprise infrastructure operations.
Strong hands-on cybersecurity experience, including incident response, vulnerability management, endpoint security, identity protection, security monitoring, and remediation.
Strong hands-on experience with Microsoft Azure IaaS/PaaS, Entra ID, Microsoft 365 security tools, Windows Server, and hybrid Microsoft environments.
Proficient in Active Directory, Group Policy, DNS, DHCP, PowerShell scripting, server hardening, patching, backups, and disaster recovery practices.
Solid understanding of cybersecurity frameworks, security controls, risk management, cloud security, endpoint protection, and identity-based security.
Experience with SIEM, EDR/XDR, KQL, vulnerability scanning, log analysis, alert triage, privileged access controls, security documentation and threat hunting.
Ability to work independently, make sound technical decisions, and operate as a technical resource without junior-level supervision.
Strong analytical, troubleshooting, and risk-based decision-making skills.
Excellent communication, documentation, and incident-reporting abilities.
Ability to work independently, prioritize competing operational and security demands, and follow through on remediation activities.
Comfortable collaborating with internal IT teams, external cybersecurity partners, and business stakeholders in a fast-paced environment.
