Duties and Responsibilities:

• Support the architectural design and strategic oversight of all network-related systems and services across the Agency, ensuring alignment with operational, technical and business needs.
• Develop, maintain, and govern network architecture blueprints, design standards, and multi-year roadmaps that support the Agency’s digital transformation and strategic IT direction.
• Provide expert guidance and assurance on network design across technologies including LAN/WAN, cloud networking, VPN, SD-WAN and zero-trust models, ensuring suitability for a multi-GSC tier environment.
• Ensure all network solutions meet required levels of security, resilience, performance and scalability, and that they are subject to appropriate architectural governance and design assurance.
• Act as a subject matter expert on networking within major programmes, actively contributing to architecture reviews, transition planning and technical assurance activities.
• Collaborate closely with the Security Architect to embed secure networking principles, controls, and threat mitigations within design and implementation phases.
• Monitor and evaluate emerging networking technologies, industry trends, and innovation opportunities, applying them where appropriate to improve capability, agility and cost-effectiveness.
• Contribute to architectural governance forums and design authorities, ensuring that network services are aligned with wider architectural standards and Agency objectives, and that assurance checkpoints are effectively met.

• Experience in designing, delivering, and assuring enterprise-grade network architectures, including cloud-native, hybrid, and multi-site environments that support high-availability and secure operations.
• Technical knowledge of core networking technologies and protocols, including routing, switching, firewalls, DNS, load balancing, VPN and network segmentation, with the ability to apply them to complex, mission-critical infrastructures.
• Experience in designing and supporting tiered secure network environments, including cross-domain connectivity, segmentation between classification levels, and the design of secure network boundaries for sensitive or air-gapped systems.
• Understanding of secure and resilient network design principles, with experience applying government or regulated sector security frameworks, such as those from NCSC, ISO, or equivalent standards.
• Experience in implementing and assuring secure and controlled data transfer mechanisms between trusted and untrusted network zones, including one-way and brokered transfer patterns where required.
• Experience in network performance tuning, telemetry, monitoring and fault diagnosis across distributed environments, ensuring reliability, scalability and alignment with operational SLAs and architectural best practices.

Desirable criteria, only to be assessed in the event of a tie break:

Have an understanding of most of the following network technologies: LAN (local area network), WAN (wide area network), wifi, data-centre LAN, SD (software-defined) networks, telephony, mobile solutions infrastructure, unified comms, network management solutions, network-specific security and remote access technologies and approaches.

We\'ll assess you against these behaviours during the selection process:
