Network Architect

DXC Technology is seeking a Network & Infrastructure Architect to lead the design and governance of the network and infrastructure estate for a major greenfield campus transformation programme.

Working under the central design authority, you will own architecture across multiple physically separated networks, covering campus LAN, high-density wireless, SD-WAN, data centre fabric, compute, storage and virtualisation. You will deliver a secure, scalable and resilient foundation throughout the programme lifecycle—from bid and solution design through implementation and transition to managed operations.

• Own the architecture for campus LAN, routing and switching, SD-WAN and high-density wireless across multiple physically separated networks.
• Design campus wireless coverage for residential, teaching and outdoor environments, including RF planning and wireless controller architecture.
• Define network topology, segmentation and secure connectivity in collaboration with the security architecture team.
• Incorporate network access control, out-of-band management and air-gapped operational technology network requirements.
• Define automation and assurance capabilities, including controller-based provisioning, topology discovery and configuration compliance.
• Design core network services, including DHCP, DNS and NTP/PTP time distribution.
• Design primary and disaster recovery site architecture, including Cisco ACI spine-leaf fabrics, multi-site orchestration and connectivity to sovereign cloud services.
• Define reference architectures for Windows/Linux compute, VMware virtualisation and SAN storage.
• Establish high availability, disaster recovery, capacity and growth models across the infrastructure estate.
• Coordinate rack, power, pathway, structured cabling and spare capacity planning with data centre and cabling teams.
• Integrate infrastructure designs with security, unified communications and cloud platform architecture.

• Develop architecture standards and reference designs aligned with programme requirements and the central design authority.
• Assure performance, availability, scalability, security and resilience throughout design and implementation.
• Guide network and infrastructure engineers, review technical designs and govern build quality against the approved architecture.
• Evaluate technology options and resolve complex design issues across a multi-vendor delivery environment.
• Support operational readiness and transition to NOC and managed services teams.
• Communicate architecture decisions, dependencies and risks clearly to technical and business stakeholders.

• Contribute to bid responses through high-level designs, bills of materials, compliance matrices and technical clarification responses.
• Ensure proposed solutions are deliverable and aligned with client requirements, architectural standards and operational needs.

• Bachelor’s degree in Computer Science, Information Technology, Engineering or a related discipline, or equivalent professional experience.
• Typically 7+ years of relevant industry experience
  , including at least 3 years in a network or infrastructure architecture or technical leadership role
  .
• Strong hands-on architecture experience across:
• Cisco Catalyst 9000 campus switching, routing and segmentation.
• Cisco ACI
  , Nexus spine-leaf fabrics, APIC and Nexus Dashboard multi-site capabilities.
• High-density Cisco Wi-Fi 6E/7 and wireless controller design.
• Cisco Catalyst Center automation and assurance, with Cisco ISE integration.
• Windows/Linux compute, VMware virtualisation and SAN storage.
• Microsoft DHCP and Active Directory-integrated DNS.
• Demonstrated experience designing high availability and disaster recovery across primary and DR sites.
• Understanding of data centre planning principles, including TIA-942 considerations, rack and power planning, pathways and structured cabling.
• Experience integrating network and infrastructure designs with firewalls, NAC, unified communications and cloud platforms.
• ** CCNP Enterprise or CCNP Data Center certification
• Strong problem-solving, stakeholder communication and delivery coordination skills.
• Professional proficiency in English.

• Experience designing large campus or multi-site environments for government, defence, higher education or critical national infrastructure.
• Experience with physically separated networks, air-gapped OT environments and sovereign cloud…
