Senior Network Engineer – ACI & Firewall for Banking Network

World Wide Technology is seeking an experienced Network Engineer in Greater London to support BAU incident resolution and troubleshooting for a merged banking network environment. This is an operations-focused role, not primarily a project deployment position.

You will handle mixed security/network stack troubleshooting, participate in after-hours changes, and contribute to stabilizing access and systems post-merger, with on-call coverage by the NOC as needed.
