• Follow operational manuals, work instructions and field playbooks, and contribute to improving procedures and ways of working.
• Work collaboratively with internal teams including Enterprise, IP Network Engineering, Digital Networks and Network Deployment, as well as external stakeholders.
• Keep current with relevant telecommunications technologies and standards, and provide coaching and on‑the‑job support to new field engineer cadets.

What makes you perfect for the role?

• Around five years’ experience in fixed transmission networks, with strong knowledge of network design and technologies.
• Understanding of transmission and digital systems, switching, consumer products and mobile systems, including 5G and edge technology.
• Knowledge of critical infrastructure including DC systems, rectifiers, batteries, PDUs, UPS systems, fire alarms and fire panels, HVAC, air handlers, chillers, grounding and DC cabling.
• Experience with facility and environmental systems, ideally in an exchange, data centre or other critical infrastructure environment.
• Strong problem‑solving skills and the ability to make sound decisions during incidents, competing priorities and uncertain conditions.
• Excellent verbal and written communication skills, with the ability to liaise effectively across technical teams, leaders, vendors, contractors and external partners.
• A strong commitment to work health and safety, site standards and responsible contractor management.
• A proactive approach to learning, continuous improvement and staying abreast of new technology.
