• Review routing, switching, DNS, load balancing and traffic management architectures.

• Identify network-related single points of failure and dependencies affecting critical services.

• Evaluate network architecture across production and disaster recovery environments.

• Assess network resilience across primary and secondary data centres.

• Review active-active and active-passive operating models.

• Evaluate network failover, recovery mechanisms and disaster recovery readiness.

• Assess connectivity resilience between regional locations and central environments.

• Identify gaps that could affect service availability during major infrastructure disruptions.

• Define target-state network architecture principles and design recommendations.

• Recommend network landing zone design patterns and improvements to network resilience.

• Assess readiness for automated failover and recovery.

• Recommend enhancements to scalability, availability and operational efficiency.

• Contribute to the development of a network transformation roadmap, including prioritisation of improvement initiatives.

• Work closely with infrastructure, enterprise architecture, security, operations and resilience teams.

• Participate in technical architecture reviews and validation workshops.

• Review architecture documentation, technical standards and supporting evidence.

• Present assessment findings, architectural recommendations and improvement priorities to senior stakeholders.

• Expertise in DNS architecture, load balancing, network segmentation and high availability.

• Strong experience in dual-data-centre architecture, disaster recovery design and network failover strategies.

• Experience conducting current-state assessments, gap analysis and future-state architecture definition.

• Ability to translate complex technical findings into practical recommendations and technology roadmaps.

• Strong communication and stakeholder engagement skills, including the ability to advise senior technology leaders.
