Overview
We're looking for a hands‑on Network Security Engineer with strong Zscaler (or equivalent SASE/SSE) experience to help bring structure and clarity to a complex, evolving environment. This role is ideal for someone who thrives in ambiguity, enjoys untangling legacy systems, and can turn one‑off solutions into repeatable, scalable processes.
What You'll Be Doing
- Analyse and map application traffic flows across complex network environments
- Lead the discovery and onboarding of applications, including undocumented and legacy systems
- Design and implement secure access models aligned to Zero Trust principles
- Work hands‑on with Zscaler or equivalent platforms (e.g. Netskope, Palo Alto Prisma Access)
- Define and standardise repeatable onboarding processes for applications
- Investigate and troubleshoot real‑world application behaviour (file transfers, batch jobs, user access patterns)
- Collaborate with PMs and BAs while acting as the technical lead/driver
- Translate technical findings into clear, actionable outcomes for stakeholders
What We're Looking For
Core Skills
- Strong networking expertise – deep understanding of traffic flow, routing, and application interaction
- A security‑first mindset – experience with Zero Trust, segmentation, and access control
- Hands‑on experience with Zscaler or similar (SSE/SASE, proxies, secure gateways)
- Solid application awareness – understanding how applications communicate and behave in real environments
Delivery & Approach
- Proven experience onboarding applications in complex or poorly documented environments
- Ability to move from ad‑hoc problem‑solving to structured, repeatable processes
- Comfortable working independently with minimal direction
- Proactive, able to hit the ground running and take ownership
Problem Solving
- Strong analytical and investigative mindset
- Comfortable dealing with ambiguity and legacy complexity
- Practical, common‑sense approach to diagnosing issues
Communication
- Confident communicator who can extract information from non‑technical or disengaged stakeholders
- Clearly explain technical concepts and recommended actions
