Are you ready to write your next chapter?
Make your mark at one of the biggest names in payments. We're looking for a Network Security Engineer Specialist to join our ever-evolving Edge &Network Security team and help us unleash the potential of every business.
This role strengthens and evolves our secure access and network security platforms across a global enterprise environment. This is a hands-on technical leadership role focused primarily on Secure Web Gateway (SWG), Proxy, SASE, Secure Access, and related network security controls, with responsibility for IPS/IDS and firewall-adjacent security capabilities.
Our core platforms include Zscaler (ZIA / ZPA) and Palo Alto Networks technologies, including Panorama, on-prem NGFW, cloud NGFW, Threat Prevention, and Prisma Access.
This role supports approximately 30,000 users globally across the US, UK, and APAC, operating in a full proxy environment with selective private access , including broad SSL inspection coverage. You will lead engineering and delivery efforts, improve service reliability, mentor other engineers, and act as a technical escalation point during high-severity incidents.
This is an engineering-first role, with approximately 80% of time focused on design, implementation, tuning, and operational improvement, and approximately 20% supporting incident mitigation and high-severity response.
On-Call Expectations: Participate in a rotating on-call schedule for incidents. Act as a senior escalation point for major issues affecting secure access, proxy, SASE, or related network security services. Contribute to post-incident analysis and ensure durable corrective actions are implemented. Participate in readiness activities, operational reviews, and resilience improvements for critical control-plane services.
