Snr Cyber Security Engineer – Zscaler Specialist

About the Role

Our client, a large enterprise operating in a highly regulated industry, is looking for a Cyber Security Engineer to join their security team with a strong focus on Zscaler. You'll provide expert technical support across the organisation's Zscaler SASE platform (ZIA, ZPA and ZDX), ensuring secure, reliable and high-performing connectivity for the business. This role suits someone who is hands-on, technically solid, and comfortable being the go-to Zscaler expert within a broader security operations function.

What You'll Be Doing
Acting as the subject matter expert for Zscaler ZIA, ZPA and ZDX, providing advanced technical support, troubleshooting and day-to-day platform administration
Managing policy configuration, traffic steering, tunnel connectivity (GRE/IPsec) and PoP routing across the Zscaler setting
Diagnosing and resolving complex connectivity, authentication, latency and application performance issues across endpoint, network and cloud layers
Supporting Zscaler platform upgrades, maintenance windows and operational changes
Contributing to Zscaler implementation and onboarding activities, including policy design,



migrations and rollout of new capabilities (implementation experience highly regarded, though the core focus is technical support)
Collaborating with network, security, endpoint and application teams to resolve SASE-related incidents and align on security policy changes
Supporting compliance reporting, audit evidence and security posture reviews in line with a highly regulated environment
Preparing incident trend and security posture reporting for internal stakeholders

About You
Robust, demonstrable hands-on experience with Zscaler (ZIA/ZPA/ZDX) is essential — this is a Zscaler-focused role and prior platform exposure is a must
Experience working in a highly regulated industry, with an understanding of frameworks such as Essential Eight and ISO 27001
Solid grounding in network and security fundamentals — firewalls (Check Point, Fortinet, Palo Alto or similar), VPNs/IPSec, IDS/IPS
Exposure to complementary security tooling such as SIEM, cloud security platforms, PAM or endpoint security is beneficial
Zscaler implementation or migration project experience is a strong plus, but not mandatory
Strong communicator, comfortable working across technical and non-technical stakeholders in a fast-paced enterprise environment
