Summary:
We are looking for a Network Engineer to join our EU network engineering team. You will help operate, troubleshoot and improve business-critical networks spanning our physical production data centers and networking services in AWS, Google Cloud and Cloudflare. This is a hands-on role across data-center networking, firewalls, application delivery, remote access and cloud connectivity, working closely with Security, Systems, Corporate IT, NOC and application teams.
Responsibilities:
- Operate and improve enterprise and data-center infrastructure, including Cisco Nexus/Catalyst switching, Fortinet FortiGate firewalls, routing, network segmentation and ISP/WAN connectivity.
- Monitor network availability, performance and capacity; diagnose outages and complex traffic-flow issues using device telemetry, logs, packet captures, tracing and protocol analysis.
- Support F5 BIG-IP application delivery services, including virtual servers, pools, health monitors and related security/access features; troubleshoot end-to-end connectivity with application owners.
- Maintain network-side VPN, remote-access and device-authentication services, including FortiGate VPN, FortiAuthenticator, TACACS+/RADIUS and role-based network access, in coordination with IT and identity teams.
- Support cloud and edge networking in AWS, GCP and Cloudflare, including DNS and traffic-delivery services such as Amazon Route 53 and AWS load balancers.
- Help maintain resilient services through high-availability design, redundant ISP connectivity, SD-WAN, monitoring, configuration backups and out-of-band recovery capabilities.
- Contribute to network architecture, capacity planning, infrastructure modernization, and resiliency improvements supporting new services and business requirements.
- Implement approved upgrades, configuration changes and service migrations using documented change controls, pre-change checks, rollback plans and post-change validation.
- Work with the NOC and application teams on incident response and approved inter-site traffic-routing/failover activities, verifying both network health and application impact.
- Participate in incident response, root-cause analysis, and the implementation of corrective actions to improve network stability and availability.
- Maintain accurate diagrams, device and circuit inventory, procedures, operational documentation and incident records; coordinate as needed with service providers and data-center remote hands.
