Network Engineer | Voice & Network Infra | Capital Markets | London, Hybrid
📍London, Hybrid | 💷Competitive Base + Bonus + Benefits | 🗓️Permanent Role
We're partnering with a global financial services organisation that is investing heavily in its infrastructure estate and is looking for an experienced engineer to join its London team.
Working as part of a global infrastructure function, you'll play a key role in designing, implementing and supporting business-critical network and unified communications platforms, ensuring high availability, resilience and security across the estate.
You'll be joining a collaborative engineering team where you'll have real ownership of critical infrastructure, exposure to global projects, and the opportunity to influence the future direction of the network and voice environment. This role offers a broad mix of BAU, project delivery, architecture and continuous improvement rather than simply keeping the lights on.
