A major banking group operating in EMEA is undergoing a significant infrastructure transformation programme, converging two separate network environments (a legacy three-tier Cisco campus network and an ACI spine-leaf fabric) alongside the integration of a European banking subsidiary. This is a hands-on senior architecture role requiring both strategic thinking and the ability to roll up sleeves and engage at detailed engineering levels.
Requirements
- Deep expertise in Cisco networking: Nexus (7K, 5K, 2K, 9K), IOS, NX-OS
- Strong working knowledge of Cisco ACI — ability to assess hybrid/pseudo-ACI deployments and define target-state app-centric or network-centric design
- Expert-level routing and switching: OSPF, BGP, EIGRP (including identification and remediation of misconfigurations)
- Data centre network design: spine-leaf, three-tier, convergence strategies
- Firewall architecture: Palo Alto (PA-40 series), Cisco ASA (legacy and migration)
- WAN/MPLS concepts and managed service architectures (NTT or similar providers)
- IP address management (IPAM) and DNS/DHCP strategies
- Network security design principles
- Familiarity with SD-WAN, cloud networking (Azure, AWS), and hybrid connectivity
Advantageous
- Cisco CCIE (Routing & Switching or Data Centre) or equivalent demonstrable expertise
- Experience with network automation and orchestration tooling
- Knowledge of co-location and proximity hosting environments
- Understanding of financial services network requirements (trading floor, market data, payment systems)
- Able to operate with ambiguity — comfortable in environments without fully defined organisational structure
- Strong communication skills: able to articulate complex technical problems to non-technical senior stakeholders
- Commercial awareness — understanding of total cost of ownership, vendor contracts, and infrastructure spend
- Collaborative and pragmatic, with the confidence to challenge incumbents and advocate for sound design principles
- Self-starter capable of providing direction to others with limited supervision
