ESN Engineer – Ericsson
Location: Reading, England, United Kingdom • Scotland – Dumfries (candidate must reside or relocate)
About this opportunity
As an ESN Engineer, you will own a designated group of sites, working as part of a four‑person team covering adjacent territories. The role requires you to be self‑managing, proactively maintaining your sites and collaborating closely with other ESN engineers and the wider FSO team to solve problems, with the goal of boosting network resilience and network availability. This position requires a flexible work schedule, including participation in a 24/7 on‑call rota and potential shift work to handle tasks outside of normal business hours. You must be prepared to travel and stay away from home for service recovery mainly on the remote islands. In a major network event scenario, you should be available to lead and complete the recovery in your own and adjoining areas.

* Conduct corrective maintenance activities and manage site facility operations.
* Take full responsibility for assigned Emergency Service Network (ESN) sites, proactively maintaining them to prevent failures and coordinating with other technical teams to resolve any issues.
* Lead problem management for your area, resolving major issues in your own and neighboring areas.
* Work individually, as part of the FSO and wider Ericsson teams to achieve the right first‑time resolution of work within customer SLAs without compromising safe working practices.
* Carry out reactive and proactive maintenance on multi‑customer, multi‑technology networks, achieving agreed performance targets (mostly EE/ESN).
* Participate in a 24×7 call‑out rota covering all equipment in the service area.
* Assist in the development and review of FSO processes and procedures with a view to maximise efficiency.
The skills you bring
* Radio Frequency (RF) transmission and receiver systems employed in mobile communication equipment.
* AC/DC power systems (single phase and three phase), UPS systems, and deployed ESN generators.
* Satellite backhaul systems.
* Rectification and power distribution systems.
* GSM, UMTS, and LTE fundamentals.
