Network Engineer - UK

You’ll join the network infrastructure and operations team of a large, regulated UK financial services organisation. You’ll provide day-to-day support of incidents and change requests, and own the installation, configuration and support of production, non-production and disaster-recovery network infrastructure. You’ll work across the full lifecycle - design, documentation, build, live transition and support - and apply modern engineering practice: Software-Defined Networking (SDN), automation and orchestration, Infrastructure-as-Code (IaC) and advanced observability, to deliver resilient, secure and scalable services.

Essential skills (all required, hands-on)

• Cisco Routing & Switching to CCNP/CCIE standard - OSPF, BGP, Spanning-Tree

• Security around internet-facing services; understanding of vulnerability assessment / penetration testing
• Scripting and Infrastructure-as-Code

Environment

Regulated financial-services network estate (Cisco core, Check Point + Cisco firewalls, Meraki, F5, Cisco ACI, cloud-integrated). Emphasis on secure, internet-facing, highly available services.

Experience

8-15 years in enterprise/regulated network engineering. CCIE (Enterprise or Security) strongly preferred given the breadth of the stack.
