Senior Infrastructure Engineer

• We lead complex project workstreams across networking, wireless, firewalls, servers, virtualisation, storage, backup, and security.
• We translate high-level designs into detailed implementation plans, task sequences, validation steps, and rollback approaches.
• We act as technical lead during cutovers, migrations, and go-live events, owning success criteria, communication points, and rollback options.
• We configure and commission core infrastructure including switching, routing, VLANs, enterprise wireless, firewalls, server builds, hypervisors, storage, and backup platforms.
• We carry out structured testing, validation, and evidence capture before handover.
• We handle third-line escalation during project delivery.
• We review documentation produced by engineers and ensure it is suitable for operational handover to Systems Operations.
• We work with Project Managers and the PMO on planning, progress, change control, and risk tracking.
• We work with Solutions Design to clarify design intent and feed back practical improvements.
• We work with Systems Operations to ensure monitoring, backup, and support readiness are in place at go-live.
• We identify delivery risks, dependencies, and blockers early and escalate with the right information.
• We mentor and coach Associate and Implementation Engineers, raising technical and documentation standards.
• We contribute to implementation standards, build guides, and configuration baselines.
• We work safely and methodically on customer and construction sites, following site rules and safe working practices.
