Alongside that, you keep our existing LTG infrastructure running reliably: you design, build, and operate complex network, server, and security systems, analyse and resolve faults, and harden our network security through scrubbers, firewalls, ACLs, and NAC. You monitor network traffic and infrastructure performance, extrapolate the KPIs that matter to management, and coordinate with external service providers and remote hands across the globe. You keep our network diagrams, runbooks, change logs, and system documentation in good shape, and you work closely with Platform Engineering on Ci
