• Assist with the administration and ongoing improvement of Fortinet, Zscaler, Akamai, Cisco Meraki, or comparable enterprise platforms.
• Review security policies, connectivity rules, logs, and alerts.
• Support network segmentation and secure connectivity across corporate, cloud, remote, and distributed locations.
• Build increasing platform ownership through formal training and hands-on operational experience.

Security Operations and Incident Response

• Monitor and investigate security events across endpoint, identity, network, and cloud platforms.
• Support containment, evidence collection, root-cause analysis, remediation, and incident reporting.
• Create and maintain security documentation, dashboards, metrics, procedures, and operational runbooks.
• Collaborate with internal teams and security-service providers during investigations.
• Identify opportunities to automate recurring security operations.

Required Qualifications

• Bachelor’s or associate degree in cybersecurity, computer science, information technology, or a related discipline, or equivalent relevant experience.

• Five or more years of combined IT infrastructure, endpoint engineering, identity administration, network support, or cybersecurity experience.

• Demonstrated hands-on experience in at least two of the following areas: o Endpoint security and endpoint detection and response o Identity and access management o Security monitoring and incident response o Cloud security o Network security and secure access

• Experience supporting enterprise endpoint, identity, networking, or security technologies.

• Working knowledge of Zero Trust, MFA, IAM, VPNs, network segmentation, cloud security, and incident-response fundamentals.

• Experience with security automation, scripting, APIs, or infrastructure-as-code.

• Ability to troubleshoot complex technical issues and document sustainable solutions.

• Ability to communicate effectively with security, infrastructure, support, application, and business teams.

Preferred Qualifications

• Experience with Microsoft Defender XDR, Microsoft Defender for Endpoint, Microsoft Sentinel, Microsoft Intune, Entra ID, or comparable platforms.
• Experience with one or more major cloud platforms, such as GCP, AWS, or Azure.
• Exposure to Fortinet, Zscaler, Akamai, Cisco Meraki, or comparable network-security technologies.
• Security+, CySA+, Fortinet, Zscaler, Microsoft, Google Cloud, AWS, Azure, CISSP, CCSP, CCNP, or comparable training and certifications.
• Experience in large, distributed, retail, restaurant, or multi-site environments.
• Experience developing operational scripts, configuration automation, security documentation, and runbooks.

Success Factors

The successful candidate will be a hands-on engineer who can independently own endpoint and identity-security initiatives while expanding into cloud, network-security, and secure-access engineering. This individual will balance operational support with architecture and automation, communicate effectively across technical and business teams, and deliver measurable security improvements at enterprise scale.
