We’re hiring for a 3rd Line Network Engineer to join our Service Desk team
You will play a key role in supporting, maintaining, and improving complex customer network environments. You will take ownership of escalated incidents, lead technical investigation through to resolution, identify root cause through problem management, present and deliver approved changes through CAB, and contribute to continual service improvement across our managed services.
You will act as a senior escalation point for the Network team, combining strong technical judgement with clear customer communication. The role requires the ability to work independently, document solutions for future use, support less-experienced colleagues, and maintain high standards of ownership from initial investigation through to resolution.
We operate on a hybrid working basis, with employees required to work from our Salford Quays office Monday to Wednesday each week.
Day to day you will:
- Manage incidents from customers and LIMA’s hosted environment on a priority basis and provide the highest standards of professionalism and skill, in order to resolve customer issues efficiently and accurately.
- Ensure customers and involved parties are updated with their incident progress either by phone or by using ConnectWise Manage (Our service desk ITSM application) in a timely manner in alignment with SLA’s.
- Act as a knowledgeable point of technical escalation, with the ability to break down technical information into clear communications for non/less-technical parties.
- Identify repeat issues and/or duplicated alerts, and work toward finding the true root cause under a problem record.
- Support our customers through planned release management processes (in and out of core hours where required) by planning, preparing, conducting, and documenting the process.
- Align to the On-Call rota as an escalation engineer that will support LIMA customers outside of standard business hours and weekends in a 1-week-in-4 rota.
- Remain forward-looking, seeking opportunity to streamline operations by shifting to proactive over reactive approaches to resolution.
- Adhere to LIMA’s operational SLA/KPI metrics, setting the standard for junior members of the service desk.
- Create, peer-review, and identify missing pieces of documentation and/or knowledge base articles.
