• Support incident response, threat detection, vulnerability management, and security monitoring
• Work across endpoint, server, network, identity, and cloud security
• Configure, monitor, and tune cybersecurity tools and security policies
• Help maintain endpoint protection, device compliance, and access controls
• Partner with IT infrastructure and leadership to identify and reduce security risks
• Assist with strengthening security across a hybrid cloud and multi-site network environment
• Participate in the continued development and maturation of the cybersecurity program

• SD-WAN
• ThreatLocker / EDR
• Cisco ISE / Network Access Control
• Endpoint and network security
• Security alerting and monitoring platforms

What We're Looking For

• Hands‑on professional experience in cybersecurity, security operations, or a SOC environment
• Experience monitoring and investigating security alerts and potential threats
• Understanding of incident response, threat detection, vulnerabilities, and security risks
• Strong fundamental knowledge of networking, endpoints, servers, and systems
• Experience working with security monitoring, EDR, endpoint protection, SIEM, firewall, or alerting technologies
• Ability to investigate a threat beyond simply responding to an automated alert
• Comfortable working in an evolving environment where security processes and technologies continue to mature
• Ability to work onsite three days per week

Preferred Certifications

Certifications are helpful but not required:

• CompTIA Security+
• CompTIA CySA+
• ISC2 SSCP
