Due to continued expansion, they are looking for an experienced Senior IT / Project Engineer to join their team, working on varied projects and having the opportunity for continuous personal development and growth.
They provide comprehensive IT support and project delivery services to SMB clients across all sectors, typically supporting organisations with 10-100 users. As part of a 20-strong engineering team, you'll work across a diverse portfolio of clients, delivering solutions in networking, Microsoft 365/Azure, security, and server infrastructure.
The Role
We're seeking an experienced Senior IT Engineer to join our 3rd Line support team. As one of the senior members of the team, you'll be a technical escalation point. This role requires someone who can diagnose complex issues, design solutions, and coordinate resources across the team to resolve challenging technical problems.
You'll work predominantly from our office or working on client sites with occasional work-from-home flexibility. This is a hands-on role that combines technical depth with client-facing responsibilities.
What You'll Be Doing
• Technical Leadership: Acting as a final escalation point for complex technical issues across networking, Microsoft 365/Azure, firewalls, and server infrastructure
• Solution Design & Delivery: Planning and implementing infrastructure projects for clients, from initial scoping through to deployment
• Client Support: Building strong relationships with clients, understanding their business needs, and translating these into technical solutions
• Team Collaboration: Working closely with 1st, 2nd and other 3rd line engineers, sharing knowledge and directing resources to resolve issues efficiently
• Continuous Improvement: Contributing to internal processes, standards, and security posture improvements
• Out-of-Hours Support: Participating in our on-call rota (1 week in 8) to provide emergency support when needed (rare) (additional pay when called)
Essential Requirements
Technical Skills
You must have demonstrable experience in the following areas:
• Microsoft 365 & Azure: Administration, troubleshooting, and solution design
• Networking: Configuration, deployment, and troubleshooting of enterprise network infrastructure
• Firewalls: Configuration and management of both hardware and software firewalls
• Server Infrastructure: Windows Server management, troubleshooting, and optimisation
• Problem Solving: Proven ability to diagnose and resolve complex, multi-layered technical issues
Certifications
• At least one Microsoft Expert-level certification (examples: Microsoft 365 Certified: Administrator Expert, Azure Solutions Architect Expert, or equivalent)
Professional Attributes
• Strong communication skills with both technical and non-technical audiences
• Comfortable working independently and making technical decisions
• Pragmatic approach to problem-solving—knowing when to leverage external resources or vendor support
• Willing to travel to client sites across North West, North Wales and surrounding regions
• Full UK driving licence
What We're Looking For
The ideal candidate is someone who:
• Enjoys the variety of working across different technologies and client environments
• Takes pride in solving challenging problems that others can't
• Values continuous learning and staying current with evolving technologies
• Understands that great IT support is as much about communication as it is technical skill
• Thrives in a collaborative team environment while being comfortable working autonomously
