Responsibilities
  • Monitor and analyze network security platforms to identify trends, risks, and opportunities for improvement.
  • Review and optimize firewall, web application firewall (WAF), proxy, and other network security policies to improve effectiveness and reduce false positives.
  • Develop and maintain SIEM use cases, alerts, dashboards, and reports to improve threat detection and visibility.
  • Perform threat hunting and detection engineering using network and security telemetry.
  • Investigate security events, analyze logs and network traffic, and support incident response activities.
  • Partner with infrastructure, engineering, and security teams to implement policy improvements and automation initiatives.
  • Build reports and metrics that communicate security posture and operational trends to technical and business stakeholders.
  • Identify opportunities to automate security workflows using scripting and other tools.
  • Maintain documentation, security standards, and operational procedures.
  • Stay current on emerging threats, attack techniques, and security best practices.
Required Qualifications
  • 5+ years of experience in a Cybersecurity or Network Security Analyst role within an enterprise SOC or security operations environment.
  • Hands-on experience with Palo Alto firewalls, Zscaler, and Imperva (or comparable WAF technologies).
  • Experience performing firewall and security policy tuning and rule optimization.
  • Strong experience with Splunk (or another SIEM), including SPL query development, alerting, dashboards, and reporting.
  • Experience with threat hunting and detection engineering.
  • Strong understanding of network protocols, traffic analysis, and common attack techniques such as lateral movement, command-and-control (C2), and data exfiltration.
  • Experience with security tools such as FireMon, BackBox, RSA, SolarWinds, Wireshark, and ServiceNow.
  • Familiarity with the MITRE ATT&CK framework.
  • Working knowledge of Microsoft Entra ID and Active Directory.
  • Experience with scripting or automation using Python, PowerShell, or similar languages.
  • Strong analytical, troubleshooting, and communication skills.
Preferred Qualifications
  • Security certifications such as GSEC, GCIA, GCDA, CCSP, or CISSP.
  • Experience working in large enterprise or hybrid cloud environments.
  • Ability to communicate technical findings and recommendations to both technical and non-technical audiences.
