About The Position

Arctiq is seeking a highly analytical and experienced Palo Alto Networks Security Engineer to support the administration, optimization, and ongoing improvement of the organization’s network security environment. This role will focus heavily on Palo Alto Networks Next-Generation Firewall (NGFW) capabilities, including application and user identification, URL filtering, traffic analysis, security policy optimization, and Cortex XDR. The ideal candidate combines strong technical expertise with sound security judgment and a disciplined approach to change management. This individual must be able to evaluate existing security rules and traffic patterns, identify opportunities to strengthen the security posture, and balance those improvements against the potential operational impact to critical business applications. This role requires strict adherence to established ITIL and change control processes, as well as the ability to work both independently and collaboratively with the broader security and infrastructure teams.

Requirements

• Strong hands-on experience administering and optimizing Palo Alto Networks NGFW environments.
• Demonstrated proficiency with: App-ID, User-ID, URL Filtering, Security policies and rule optimization, Firewall traffic and log analysis
• Experience with Cortex XDR and endpoint/security event analysis.
• Strong understanding of network security concepts, firewall architectures, application traffic, and security policy design.
• Advanced analytical and troubleshooting skills, with the ability to interpret complex traffic and log data.
• Demonstrated ability to assess security improvements while considering potential business and application impacts.
• Strong understanding of ITIL and formal change control processes.
• Experience making security policy changes in environments where service availability and operational stability are critical.
• Ability to document, test, and validate changes before implementation.
• Experience with Palo Alto APIs, CLI tools, Python, or other scripting/automation technologies.
• Strong written and verbal communication skills.
• Ability to work effectively as part of a team while also independently managing assigned technical responsibilities.

Nice To Haves

• Palo Alto Networks certifications such as PCNSA, PCNSE, or PCCET.
• Experience with large-scale or enterprise Palo Alto firewall environments.

Responsibilities

• Administer, analyze, and optimize Palo Alto Networks NGFW environments and security policies.
• Leverage advanced Palo Alto capabilities, including App-ID, User-ID, URL Filtering, and related security controls.
• Analyze firewall traffic, logs, sessions, and security events to identify threats, policy inefficiencies, and opportunities for security improvement.
• Evaluate existing firewall rules to identify opportunities for rule consolidation, modification, cleanup, and removal while maintaining appropriate security controls.
• Apply strong analytical judgment when determining whether tightening a security rule provides sufficient security benefit relative to the potential operational impact on critical business applications.
• Investigate application traffic and connectivity issues and determine appropriate firewall policy adjustments without unnecessarily weakening security controls.
• Support and administer Cortex XDR, including analysis of alerts, endpoint security events, and associated telemetry.
• Follow established ITIL, change management, and security governance processes for all firewall and security policy changes.
• Ensure rule deletions, consolidations, and modifications are thoroughly tested, documented, reviewed, and approved prior to implementation.
• Maintain accurate documentation of security policies, changes, testing results, and operational impacts.
• Proactively identify opportunities to improve firewall performance, security posture, policy efficiency, and operational processes.
• Develop and utilize APIs, CLI tools, Python, or other scripting languages to automate repetitive security and firewall administration workflows.
