We are a fast-growing Managed Services Provider delivering connectivity, networks, firewalls, Microsoft cloud, and cybersecurity solutions. We partner with UK SMEs, commercial real estate landlords, and high-growth businesses to design, deliver and support resilient, secure, and scalable technology environments.

Our focus is on solving complex infrastructure challenges with precision, speed, and a deep understanding of our customers' needs. As we continue to evolve our services, including modern security and automation-led delivery, we are building a team that thrives on ownership, continuous improvement, and technical excellence.

Our culture is driven by our values: Be Fast, Stay Curious, Get it Done, Always Growing, Go Further. These define how we deliver for our customers and how we develop our people.

We are seeking a skilled Service Delivery Engineer to join our Service Operations team, responsible for delivering and implementing customer solutions across network, connectivity, and security environments. This role is suited to an engineer with a service provider mindset who takes pride in delivering high-quality solutions right first time and continuously improving how services are delivered.

You will also play a key role in adapting deliveries where requirements evolve, ensuring changes are effectively managed and communicated.

Alongside delivery, you will maintain accurate documentation and system updates to support ongoing service management, and provide occasional escalation support to the Service Desk for customer-specific issues. This role goes beyond delivery execution; you will contribute to the continual improvement of our services by helping standardise and industrialise delivery processes, improving tooling and knowledge, and enhancing the overall customer experience.
