Senior Network Engineer – Broadcast Network Migration
Department: Broadcast Project: Management Network Migration & Network Refresh
We are looking for an experienced Senior Network Engineer / Network Design Engineer to join a major network migration and refresh programme within our Broadcast division. The project involves migrating an existing management network away from our existing environment, while simultaneously delivering a refresh of the underlying network infrastructure. This is a hands-on technical role requiring strong Cisco and Juniper networking expertise, with the successful engineer taking ownership of key elements of the network design, migration planning, testing and implementation. You will be responsible for developing the technical approach to the migration, producing detailed design documentation, implementation runbooks and test plans, and helping ensure the network can be migrated with minimal disruption to existing broadcast services.
Key Responsibilities
- Drive the design and migration of the existing management network
- Support the parallel refresh and modernisation of the network infrastructure
- Design and configure BGP routing
- Design and troubleshoot IPsec tunnels, GRE tunnels and VPN connectivity
- Work with management gateways/headends and associated management network connectivity
- Design and validate ingress and egress network paths, ensuring appropriate inbound and outbound connectivity to management and production networks
- Configure and troubleshoot routing between management gateways and the wider network
- Develop and implement QoS policies
- Design and implement solutions across Cisco and Juniper environments
- Produce detailed Low-Level Designs (LLDs), migration plans and implementation runbooks
- Develop comprehensive network test plans and acceptance criteria
- Perform pre- and post-migration testing and troubleshooting
- Identify migration risks, dependencies and potential service impacts
- Work closely with engineering, architecture, operations and broadcast teams throughout the migration lifecycle
Essential Technical Experience
- Cisco networking
- Juniper networking
- BGP – essential
- IPsec
- GRE tunnelling
- VPN technologies
- QoS
- Cisco IOS
- Cisco IOS XR
- Routing and switching
- Network gateway/headend architecture
- Ingress and egress routing/connectivity
- Management network design
- Network migrations and infrastructure refresh programmes
Desirable Experience
- Experience within any of the following would be particularly beneficial:
- Broadcast / media networks
- Large-scale service provider or telecommunications environments
- Complex, highly available production networks
- Management/OOB network architecture
- Large-scale network migration programmes
- Working within a Tier 1 telecommunications environment
Candidate Profile
The successful candidate will be a senior-level network engineer who is comfortable owning technical design rather than simply implementing an existing design. You should be capable of taking a migration requirement, understanding the existing network architecture and traffic flows, designing the target solution, documenting the migration approach, developing the runbooks and test strategy, and supporting the implementation through to completion. Strong troubleshooting skills and a detailed understanding of routing, tunnelling, gateways and network traffic flows will be essential.
