Department Overview

At MJ Quinn, technology is a business enabler — not just a support function. Our Technology and Services Department supports around 5,000 colleagues across multiple locations, platforms, and workstreams, ensuring our people have the tools, systems, and support they need to succeed.

We have full ownership of our Microsoft modern workplace estate, including Microsoft Dynamics, giving us the autonomy to design, improve, and innovate rather than simply maintain. This is a forward‑thinking environment where technical expertise is trusted, continuous improvement is encouraged, and high standards matter.

JOB OBJECTIVE

The 3rd Line IT Support Engineer plays a critical role in maintaining the reliability, security, and performance of MJ Quinn’s IT services. This is a senior technical position, acting as the escalation point for complex issues and a key contributor to the ongoing optimisation of our IT environment.

You’ll operate in a fast‑paced, dynamic environment where no two days are the same. The role balances reactive problem‑solving with proactive improvement, giving you the opportunity to influence how systems are designed, supported, and evolved as the business grows.

Alongside deep technical expertise, this role requires a confident and effective communicator who is comfortable engaging with key stakeholders at all levels. You’ll translate complex technical challenges into clear, meaningful updates for non‑technical audiences, while working closely with technical peers on detailed solutions and improvements.

As a senior member of the team, you’ll take an active role in mentoring and supporting 1st and 2nd Line engineers, sharing knowledge, encouraging best practice, and helping to raise capability across the service.

MJ Quinn is committed to continuous personal and professional development. You’ll be fully supported through our training enablement programme, giving you the freedom to learn, upskill, and pursue relevant technologies and certifications. If you’re motivated, curious, and willing to invest in your own development, you’ll have the backing to learn and grow your expertise.

Working closely with colleagues across IT and the wider business, you’ll act as a trusted technical advisor — combining technical excellence with a pragmatic, service‑focused approach that supports MJ Quinn’s objectives.
