We're recruiting for a Senior Network Infrastructure Engineer to join a highly technical telecoms and communications environment where network performance, resilience, and uptime are absolutely critical to the wider business.

You’ll work closely with senior leadership and technical teams, acting as a key escalation point while helping to drive standards, performance, and operational stability across the environment. The role offers the chance to work across carrier-grade networking, high-availability telecoms platforms, on-prem infrastructure, and network architecture, making it a strong move for someone looking to continue progressing into a broader infrastructure leadership or future CTO-level pathway.
