Job description

Looking for a role with plenty of growth opportunities?

Join a leading UK broadcast and satellite media technology provider, part of a major international telecommunications group, delivering resilient and secure network infrastructure for hundreds of live television channels, internet, and private customer networks. The organisation is currently undertaking a major IP migration, modernising legacy broadcast technology onto carrier-grade infrastructure.

The role offers hands-on ownership of a live IP migration project, with exposure across the full network stack, alongside the opportunity to work within a stable, collaborative team of around seven. The position provides a global network footprint across UK and French operations, hybrid working with two days in the office and three from home, and currently has no on-call requirement.

Responsibilities

• Manage and operate core network architecture supporting carrier-grade, multi-site infrastructure carrying live broadcast, internet and private customer traffic
• Lead and support a major IP migration project, moving legacy broadcast technology onto current-generation infrastructure
• Manage, operate and improve the multisite network for multicast TV transport as well as the internal campus network
• Design and support customer networking solutions across multiple sites, including remote access
• Own network security and firewall configuration in a fast-changing environment
• Split time roughly 50/50 between project work and BAU: ticket resolution, solution specification and materials/billing documentation, shared across the wider team
• Create and maintain accurate network documentation, including complex diagrams
• Manage and operate the organisation's network monitoring systems (NMS)

Skills/Must Have

• Experience: 5+ years' hands-on experience supporting a multi-site, enterprise-grade network environment
• Core Tech/Domain: Strong Cisco routing and switching (R&S) background; comfortable covering the full network stack rather than a single specialism
• Methodology/Protocols: Solid working knowledge of VLANs, 802.1Q trunking, STP/RSTP/MST, LACP/port-channels, OSPF, EIGRP, BGP, plus practical firewall configuration and troubleshooting, ideally on Palo Alto (NAT, security policy, VPN, HA)
• Soft Skills: Self-motivated and comfortable working independently and within a small team; strong troubleshooting instincts, clear communicator, commercially aware when engaging with customers

Desirable Skills

• Multicast experience (SSM/ASM) in Layer 2/3 environments
• Broadcast or media-over-IP background
• Cisco IP Fabric for Media (IPFM) experience
• Net Insight Nimbra experience
• CCNP certification (or working towards)

Benefits

• Up to 10% annual bonus
• 25 days annual leave
• Pension
• Private medical insurance and life insurance
• Hybrid working (2 days office / 3 days home)

Salary

• Up to £65,000 base + up to 10% bonus.
