Overview

Join to apply for the ESN Engineer role at Ericsson

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.

This role is based in Scotland and reports directly to the Regional Manager. We currently have vacancies in Kyle of Lochalsh, Dumfries, Oban, and Lochinver. Applicants should already reside in, or be willing to relocate to, one of these areas within a few months of appointment.

• 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 lead coordination with other technical teams to resolve issues.
• Take a leadership role in problem management for your area, resolving major issues in your own and neighbouring areas.
• Work individually and with the FSO and wider Ericsson teams to achieve right‑first‑time resolutions 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 24x7 callout rota covering all equipment in the Service Area.
• Assist in the development and review of FSO processes and procedures to maximise efficiency.

The skills you bring

• RF Transmission and Receiver systems used 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
