Job Description

The Role

We are looking for a senior infrastructure engineer who naturally leads from the front.

This is a hands-on technical role first, with team leadership responsibilities second. You will be the escalation point for complex issues, guide technical standards, and help the infrastructure team operate with consistency and accountability.

This role suits someone who enjoys solving real problems, improving environments, and mentoring engineers, not someone looking to move away from the tools.

• Coaching engineers and setting technical standards

You will also

• Help manage ticket flow and priorities
• Support SLA performance and service quality
• Run structured 1:1s and technical guidance sessions
• Work closely with Projects, Networking and Security teams

This is a delivery-focused leadership role within a fast-moving MSP environment.

• Microsoft 365 and Azure
• Patch management and security baselines
• Monitoring and RMM tools

2. Exposure to security and compliance practices is important, including:

• Infrastructure hardening
• Vulnerability remediation

MSP experience is highly valued.

Leadership & Communication

Key attributes

• Clear communicator with technical and non-technical stakeholders

• Leads by example and sets standards
• Holds themselves and others accountable

What Success Looks Like
