Senior Network Engineer – Core Infrastructure & Connectivity

Location: London

Salary: 75-95k€

For one of our clients we’re looking for a skilled Senior Network Engineer to help build and maintain resilient, high-performance network infrastructure that supports critical real-time environments. This position is ideal for engineers with deep routing expertise, strong architectural insights, and experience delivering robust network solutions in demanding enterprise settings.

What you’ll do

Translate designs into detailed configurations and deployment plans, working closely with architecture leadership to ensure feasibility and operational excellence.
Lead implementation of core network infrastructure projects focused on availability, scalability and performance across distributed systems.
Configure and manage network routing, switching and security components, with emphasis on strong access controls and segmentation following modern principles like least-privilege/zero-trust.
Deliver 3rd-line operational support and escalation management for critical production incidents, including deep diagnostics and root cause analysis.
Establish and maintain network standards, best practices, and operational playbooks to support consistency and compliance.
Onboard and configure new connectivity with external partners and hosted environments, ensuring reliable integration and performance.

Your profile

Proven hands-on experience designing, deploying and operating Layer-3 routing architectures, including multi-peer BGP, VRF and resilient topologies.
Strong routing, switching and network troubleshooting skills, capable of deep-dive analysis across LAN, WAN and data centre environments.
Familiarity with infrastructure hardware (e.g., enterprise switches/routers) and resilient network design patterns prioritising high throughput and low-latency delivery.
Solid foundation in network security concepts and configuration management to enforce secure practices.
Excellent communication skills with an ability to document and articulate complex designs, technical decisions and operational processes.

Desirable

Experience with infrastructure automation tooling (Terraform, Ansible) and scripting languages such as Python to support configuration management and process automation.
Exposure to network observability, telemetry or performance-monitoring tooling.

Why this is exciting

Work on core connectivity systems that are essential to mission-critical operations.
Influence architectural decisions and help shape engineering standards within a technology-driven team.
Opportunity to solve challenging problems and expand your domain expertise within a fast-moving environment.
