About the Role
IMG, a leading global sports marketing agency and subsidiary of TKO Group Holdings, is building a new broadcast headquarters at One Chiswick Park: a greenfield, software-defined, IP-first facility producing and delivering live sport 24/7. The Senior Network Engineer will join the network function at the centre of this build, helping commission the new estate through the project phase and then owning its day-to-day engineering as part of the run team.

This role bridges traditional networking and modern NetOps practices. The new estate is automation-first: every device is modelled in a NetBox source of truth, configuration is deployed from code through pipelines rather than hand-edited, and streaming telemetry feeds the observability stack. Changes are expected to land in days, not months, in a facility where the network carries live content around the clock.

The estate spans dedicated SMPTE ST 2110 media networks with PTP timing, EVPN/VXLAN leaf-spine service fabrics, a lossless fabric for emerging media-exchange and compute workloads, enterprise-class firewall estates, and a DWDM dark fibre WAN with dedicated cloud interconnects. You will work alongside the systems integrator during the build, with broadcast and corporate teams day to day, and act as a senior escalation point for the operation.

This position suits engineers from broadcast, media, ISP or carrier backgrounds who want to build a modern network from a blank slate and then run it.

Key Responsibilities
- Fabric and media network engineering including core routing and switching: design, operate and troubleshoot leaf-spine fabrics using BGP, OSPF, EVPN/VXLAN overlays, VRF-separated services, and routed access.
- Operate the ST 2110 media network environment with SMPTE 2022-7 protection, PTP timing discipline, and NMOS control to meet live production standards.
- Maintain advanced, production-grade multicast (PIM-SM with anycast RP, IGMPv3, scoped boundaries) for media and encoded distribution networks.
- Manage capacity, firmware, and hardware lifecycles across the estate; plan upgrades without service impact in a 24/7 facility.
- NetOps and automation: maintain NetBox as the authoritative source of truth; build and run automation pipelines (Python, Ansible, Git) to deploy configuration as code; develop monitoring using streaming telemetry and modern tooling (Grafana, Zabbix).
- Lead the shift from manual workflows to automated NetOps and mentor colleagues.
- WAN, cloud and security: operate eBGP edge across DWDM dark fibre paths with BFD; manage dedicated cloud interconnects (AWS Direct Connect class); hands-on firewall management and network hardening within a security-by-design framework.
- Support lab validation, commissioning, and migration of live services from Stockley Park to One Chiswick Park.
- Act as a Level 3 escalation point and mentor engineers across broadcast IT and operations teams.

Experience
- Advanced TCP/IP, switching and routing (BGP, OSPF) in production environments.
- Experience operating EVPN/VXLAN leaf-spine fabrics.
- Advanced multicast protocol experience in production (PIM-SM, IGMPv3).
- Demonstrable Python and Ansible skills for network automation with Git-based workflows.
- Experience with NetBox or similar IPAM/DCIM platforms; NetBox preferred.
- Practical experience with modern monitoring tools (Grafana, Zabbix, ELK), flow analysis, and streaming telemetry.
- Proven experience managing and securing enterprise firewall estates (Palo Alto, Fortinet, Cisco) and firmware lifecycles.

Advantageous
- Broadcast media network knowledge: SMPTE ST 2110, PTP timing and synchronisation, SMPTE 2022-7, NMOS.
- Real-time transport protocols: RTP, UDP, SRT, RIST, Zixi; error correction methods (FEC, ARQ); video encoding awareness (AVC, HEVC, JPEG-XS).
- Experience with lossless fabrics (RoCEv2/RDMA, PFC/ECN) and media-exchange workloads.
- Optical and WAN technologies: DWDM, dark fibre, optical link budgets, circuit diversity.
- Vendor platforms: Arista EOS (CloudVision, AVD) and/or Cisco NX-OS (Nexus Dashboard) at data centre scale.
- Familiarity with version control beyond scripts (GitHub or similar) and project tools such as Jira or ClickUp.

About You
- Excellent communication skills, able to articulate complex technical concepts clearly to both technical and non-technical stakeholders including production teams.
- Ability to remain accurate and calm under pressure in a live broadcast environment.
- Organised, self-motivated, and proactive with a strong preference for solving problems through automation rather than manual repetition.

Success at IMG is driven by four core competencies:
- Business Acumen: Understanding financial drivers, interpreting business data, aligning decisions to strategic outcomes.
- Operational Excellence: Driving efficiency, governance, and continuous improvement in delivery and operations.
- Innovation Mindset: Cultivating curiosity, experimentation, and forward-looking capability development.
- Leadership & Collaboration: Inspiring others, building trust, and enabling collaboration across teams.

Qualifications
Relevant professional certifications or qualifications in networking, automation, or broadcast technology are advantageous but not mandatory. A strong track record of hands-on experience and continuous learning is essential.
