Job Description

The Senior Network Security Engineer will provide technical leadership across the support, configuration, optimisation and continuous improvement of customer network security environments. The role requires a strong, demonstrable hands-on background in enterprise networking, firewalls and cloud/hybrid infrastructure, including Microsoft Azure networking. The successful candidate must be able to personally investigate, configure, troubleshoot and resolve complex technical issues, rather than relying solely on scripts, runbooks or other teams to complete the technical work.

- Support, configure, manage and optimise enterprise network security devices, including Palo Alto, Fortigate, Cisco firewalls and other customer-specific platforms.
- Act as a senior technical escalation point for complex Level 2/3 incidents, service requests, root cause analysis and major technical issues.
- Plan and deliver network and security changes in line with change management policies, ensuring appropriate risk assessment, testing, rollback planning and customer communication.
- Independently diagnose and resolve network and security issues through direct analysis of configurations, logs, packet flows,



routing behaviour and platform diagnostics, escalating only when appropriate.
- Maintain, improve and assure technical documentation for customer network environments, including diagrams, configuration standards, operational procedures and support handover material.
- Provide hands-on support and configuration for Azure networking components, including VNets, subnets, network security groups, route tables, VNet peering, hub-and-spoke connectivity, VPN gateways and ExpressRoute-related network integration.
- Implement and improve network security tools, policies, standards and procedures in line with customer requirements, industry positive practice and operational governance.
- Provide technical guidance to engineers, support knowledge sharing across the team and contribute to service improvement initiatives.
- Co-ordinate with vendors, customers and internal IT teams to drive issues to resolution and ensure clear ownership of actions.
- Proactively identify risks, recurring issues and opportunities to improve resilience, security posture, monitoring and operational efficiency.
