A growing organisation is looking to add an experienced 3rd Line IT Engineer to its internal technology team.

This is a hands‑on position for someone who enjoys being the person others turn to when an issue needs more than a standard fix.

You'll take ownership of complex escalations, work directly with users and senior stakeholders, and play an active role in keeping the wider IT environment running smoothly.

It's an environment where you'll be visible within the team, so we're looking for someone technically strong who is also approachable, confident and enjoys working closely with people.

What you'll be doing

  • Take ownership of complex 3rd line escalations, investigating issues through to resolution.
  • Provide hands‑on support across Microsoft 365, Windows, Active Directory and Entra ID.
  • Administer and troubleshoot Intune, including device configuration, application deployment and endpoint policies.
  • Support Windows Server and wider infrastructure environments.
  • Troubleshoot networking issues across DNS, DHCP, VPN, Wi‑Fi and connectivity.
  • Support laptops, desktops and other end‑user technology throughout their lifecycle.
  • Provide technical support to senior stakeholders and key users.
  • Support meeting room, AV and workplace technology.
  • Work with external suppliers and specialist technical teams where required.
  • Contribute to infrastructure projects, upgrades and continuous improvement.
  • Maintain clear technical documentation and knowledge articles.
  • Share knowledge and support less experienced members of the team.

What we're looking for

We're looking for someone with proven 3rd line experience rather than someone looking to make their first move beyond 2nd line.

You’ll ideally have

  • Strong experience in a senior IT support, 3rd line or infrastructure support position.
  • Hands‑on Microsoft 365 administration experience.
  • Strong Active Directory and Entra ID knowledge.
  • Practical Intune experience.
  • Good Windows Server knowledge.
  • Strong troubleshooting skills across desktop, endpoint and infrastructure.
  • Good understanding of core networking.
  • Experience handling complex escalations and senior users.
  • A track record of taking ownership rather than simply passing issues on.

The person

Technical ability is important, but so is how you work with people.

We're looking for someone who is

  • Approachable and personable
  • Confident dealing with users at all levels
  • Comfortable being a visible member of the IT team
  • A strong communicator who can explain technical issues clearly
  • Calm and professional when dealing with difficult problems
  • Happy to support and mentor colleagues
  • Naturally proactive and willing to get involved Someone who takes pride in providing a good service

The opportunity

This is a chance to join an established internal IT function where you'll have genuine ownership and visibility.

You’ll be trusted to solve problems properly, contribute ideas, support the wider team and help improve the service rather than simply working through a queue of tickets.

If you're an experienced 3rd line engineer who knows your stuff but is also someone people enjoy working with, we'd like to hear from you.

How to prepare for a job interview at LGBT Great

Brush Up on Your Technical Skills

For an IT consulting role, be ready to demonstrate your technical prowess. You might face questions on systems integration, cloud technologies, or even troubleshooting specific software. If you have experience with tools like AWS, Azure, or even specific programming languages, make sure you can talk about them fluently.

Showcase Your Problem-Solving Approach

IT consulting is all about solving problems for clients. Think about how you can illustrate your approach to a past challenge using the STAR method (Situation, Task, Action, Result). It's a great way to show how you tackle complex issues and come up with effective solutions.

Know the Business Impact of IT Solutions

When discussing your experiences, focus not just on the tech solutions you implemented, but also on their business impact. Employers want to see that you can connect IT with organisational goals. Prep examples that highlight how your tech contributions improved efficiency or reduced costs for past clients or projects.

Prepare for Behavioural Questions

Since IT consulting often involves teamwork and client interactions, expect behavioural questions that assess your interpersonal skills. Be prepared with examples that demonstrate your adaptability, communication skills, and how you handle client feedback. Before the interview, think of situations where you worked closely with clients to create effective IT strategies or changes.
