• Produce designs that support automation-first, CI/CD-driven deployment models
• Convert manual network configurations into automated configuration templates
• Validate and test network designs directly in public-cloud environments
• Partner closely with engineering and architecture teams to deliver network solutions across multiple cloud migration initiatives
• Support stakeholder engagement across technology, infrastructure, and platform teams

What You’ll Bring

• Extensive experience designing and delivering end-to-end IP network solutions, with a strong focus on cloud environments (public, private, or hybrid)
• Proven experience producing IP design documentation (HLD/LLD)
• Strong track record of taking designs from concept through to production-ready implementation
• Deep IP networking expertise across physical infrastructure and public cloud platforms
• Hands-on experience with AWS networking, Cisco, and Palo Alto technologies
• Experience designing telco networks using ISIS, MPLS-SR, MP-BGP, LDP, QoS, and network security controls
• Working knowledge of Netconf/YANG and network automation concepts
• An automation-focused mindset with the ability to design scalable, repeatable solutions

Team & Environment

You’ll join a high-impact Communications & Infrastructure function, working alongside specialists in broadband, telephony, mobile, cloud, and core infrastructure. The team designs, builds, and supports large-scale telecom networks that underpin digital services used by millions of customers.

Benefits & Perks

• Competitive salary and generous pension scheme
• Private healthcare
• Discounts on TV, mobile, and broadband services
• Access to exclusive rewards, experiences, and benefits programs
• Hybrid working model combining office collaboration and home working
• Modern office location in East London, close to major transport links
