Role Overview

A leading enterprise organisation is seeking a highly technical Security Engineer to support a major Secure Web Gateway migration from Skyhigh (McAfee Web Gateway) to Blue Coat (ProxySG / Symantec / Broadcom).

This role requires a true proxy engineer — someone with hands-on experience of SWG platforms who can translate policies, troubleshoot traffic flows, and own the migration workstream rather than follow scripted procedures.

Key Responsibilities

• Lead and deliver Secure Web Gateway migration activities from Skyhigh to Blue Coat
• Translate and rebuild proxy policies, SSL inspection rules, and exceptions
• Troubleshoot authentication, traffic flow, and policy issues during cutover
• Work closely with network teams to manage traffic steering and proxy routing
• Support testing, validation, and optimisation of the new proxy platform
• Own assigned migration workstreams end-to-end

Required Technical Experience

• Hands-on experience with Skyhigh Web Gateway and/or McAfee Web Gateway (MWG / CWS)
• Hands-on experience with Blue Coat / ProxySG / Symantec / Broadcom
• Strong understanding of Secure Web Gateway / proxy architectures

Experience with:

• PAC files
• SSL/TLS inspection and bypass
• Proxy authentication (Kerberos / NTLM / headers)
• Explicit proxy traffic
• Proven ability to troubleshoot proxy traffic at depth

Supporting Infrastructure (Desirable)

• F5 or AVI load balancers
• Fortinet firewalls
• Bluecat DNS
• Enterprise network environments

Key Attributes

• Highly technical and hands-on
• Able to work autonomously and own delivery
• Comfortable operating without step-by-step runbooks
• Experience in regulated or large-scale enterprise environments preferred
