We are looking for someone who is dependable, calm under pressure and methodical when troubleshooting. You will need to be comfortable working independently, taking ownership of issues and projects through to completion, while also being a strong team player with a customer-focused approach.

This is an excellent opportunity for a Senior Network Engineer looking for a technically challenging role with exposure to ISP, datacentre, MSP and enterprise environments. You will have the opportunity to work on complex infrastructure, take ownership of significant network projects and continue developing your technical expertise across multiple technologies.
