ABOUT THE ROLE

This is a hands-on, highly technical role responsible for securing JLL's global network infrastructure. The ideal candidate brings a security-first mindset, a bias towards action, and deep expertise in Palo Alto Networks technologies alongside broad command of API security, WAF/CDN platforms, and complex troubleshooting across network and application layers. You'll work collaboratively with global engineering, application, and security teams to ensure security controls are intelligence-driven, optimized, and aligned to industry best practices.

PRIMARY RESPONSIBILITIES
  • Serve as the primary subject matter expert for Palo Alto Networks technologies (NGFWs, Cloud NGFW, Panorama), Web Application Firewall, Content Delivery Network, API Security, IDS/IPS, and DDoS prevention
  • Own onboarding, policy tuning, and lifecycle management for WAF and CDN platforms; lead firewall ruleset optimization, IDS/IPS tuning, and DDoS protection configuration
  • Partner with internal teams to drive the global rollout, tuning, and operational management of URL filtering and TLS decryption across the network estate
  • Lead API security efforts - ensuring API traffic routes through security tooling, identifying vulnerabilities, and working with application teams on fixes
  • Lead troubleshooting of complex, multi-layer global network and application issues - from packet captures on inter-continental BGP topologies to WAF false-positive triage
  • Partner with business and application teams to produce clear, actionable security documentation, change proposals, and executive-ready findings
  • Analyze existing network security architectures, processes, and procedures to identify gaps and drive meaningful improvements
  • Configure and report on defensive measures against advanced threat actor tactics; maintain current awareness of the evolving threat landscape and the effectiveness of our defenses against them
  • Communicate complex technical problems and solutions clearly to both global engineering teams and C-suite stakeholders
  • Champion the broader Security team's initiatives, not just Network Security Engineering
  • Participate in the maintenance and tuning of all network security technologies including WAFs, CDNs, VPNs, and application-aware firewalls
  • Leverage and contribute to automation pipelines for global firewall rule deployment and policy management across the network estate
  • Utilize security tooling telemetry and data collection automations to produce actionable reporting and metrics for internal teams and executive stakeholders

REQUIRED QUALIFICATIONS
  • 5+ years of hands-on network security engineering experience designing and implementing enterprise-scale security solutions
  • Expert-level proficiency in Palo AltoNetworks - NGFWs, Panorama policy management, and PAN-OS; PCNSE or PCNSC certification strongly preferred
  • Expert troubleshooting skills across network and application layers, including packet capture analysis on complex, dynamically routed architectures
  • Deep understanding of layer 7 web application technologies and WAF/CDN platforms (e.g. Akamai, Cloudflare, Imperva, F5) - onboarding, policy tuning, break/fix troubleshooting, and operational management
  • Solid grounding in API security - ensuring API traffic routes through security tooling, evaluating identified vulnerabilities, and partnering with application teams to drive remediation
  • Strong HTTP/application security knowledge: TLS interception, SQL injection, XSS, CSRF, command injection, LFI/RFI, rate limiting, bot detection, geo-blocking, and sinkholing
  • Intermediate to advanced network routing and switching knowledge with focus on DNS, TCP/IP, IPsec, TLS, GRE, OSPF, and BGP
  • Proficiency in at least one scripting language (Python preferred) and familiarity with Linux/CLI tooling
  • Working knowledge of public cloud environments (Azure, AWS, GCP)
  • Experience with at least one SIEM platform for log analysis, behavioral analytics, and rule tuning
  • Proven written and verbal communication skills, including presenting to both technical and non-technical audiences
  • Proven track record of taking ownership in unstructured environments - cutting through ambiguity, making sound decisions with incomplete information, building stakeholder consensus, and delivering security improvements without waiting for top-down direction

PREFERRED QUALIFICATIONS
  • Industry certifications: PCNSE, PCNSC, CCNP/CCIE Security, GIAC (GWAPT, GPEN, or similar)
  • Experience building metrics pipelines and KPI reporting for security operations
  • Familiarity with interconnecting disparate security technologies to solve unique application and security challenges
