About our clientOur client is delivering a large-scale, mission-critical infrastructure transformation programme of national significance, focused on modernising core platforms within a highly secure and regulated setting.This programme spans multiple data centres and secure environments, forming part of a broader enterprise-wide uplift of critical infrastructure capability.
It involves the migration of legacy virtualised environments into a modern, highly segmented and secure architecture powered by Cisco ACI and next-generation networking principles.Operating within a Defence-aligned environment, the infrastructure being built and transitioned is fundamental to ongoing operations, meaning every change, configuration and cutover must be executed with precision, discipline and zero margin for error.This is a complex, multi-stream programme delivered in structured migration waves, where network stability, segmentation and connectivity are critical to the success of the overall transformation.About the roleYou will play a key role in the execution layer of the network transformation, working hands-on within migration waves to ensure seamless delivery across a Cisco ACI-driven architecture.This role sits at the centre of delivery — you will be working directly on cutovers, transitions and live environment changes, ensuring network integrity across compute, storage and VDI workloads.Key responsibilitiesConfigure and manage Cisco ACI fabric, including EPGs, Contracts, policy enforcement and segmentationExecute DNS, DHCP and IP transition activities aligned to migration waves and cutover schedulesSupport and deliver network cutovers within tightly controlled maintenance windowsValidate and monitor network isolation and micro-segmentation policies during migrationTroubleshoot connectivity issues across compute, storage and VDI layersWork closely with architects and engineers to ensure designs are implemented correctly and consistentlySupport high-pressure migration events,



ensuring minimal disruption to critical servicesThis is a hands-on, delivery-focused role, operating in an environment where attention to detail, speed of execution and technical accuracy are critical.The successful candidateYou are a strong network engineer who thrives in high-pressure, high-impact delivery environments, and is comfortable working within large-scale transformation programmes.5–7+ years experience in enterprise network administrationProven hands-on experience with Cisco ACI environments (EPGs, Contracts, segmentation)Strong understanding of network segmentation, IP addressing, DNS/DHCP and migration cutoversExperience supporting data centre migrations or large-scale infrastructure transitionsStrong troubleshooting capability across multi-layered environments (network, compute, storage)Able to operate calmly and effectively during critical cutover windowsNV2 clearance preferred, OR NV1 with NV2 actively in progress (mandatory for consideration)What is on offer$170,000 + super + performance bonusOpportunity to work on a mission-critical programme supporting nationally significant systemsLong-term engagement (initial 2-year fixed term contract with strong extension potential)Melbourne or Adelaide preferred, with flexibility for FIFO arrangements across AustraliaWork alongside high-calibre architects and engineers in a high-performing delivery teamExposure to cutting-edge network technologies in a complex, large-scale environmentWhy this opportunity stands outThis is not a BAU network role.You will be working at the centre of a live transformation programme, contributing directly to the delivery of infrastructure that supports critical national capability.The environment is fast-paced, highly structured and demanding — but it offers the opportunity to build experience at scale, work with leading technologies, and be part of something genuinely meaningful.If you're looking to step into a role where your work has real impact, real complexity and real purpose, this is it.
