The Network Engineer is responsible for the day-to-day management, optimisation, and operational delivery of customer network environments across both AWS and physical infrastructure. While AWS and cloud networking form a significant part of customer estates, this role also has a strong emphasis on remote management of physical networks, switches, firewalls, and access infrastructure.

The role ensures that customer networks are secure, resilient, well-documented, and aligned with best practice, while delivering exceptional service experiences consistent with IT Naturally’s ISO 20000-aligned service standards and B Corporation values.

A key part of this role is curiosity and ownership. We are looking for someone keen to learn, investigate existing environments, and proactively document how things work, using their own initiative to improve visibility, resilience, and operational maturity.

The key purpose of the role is to:

• Own the operational and networking aspects of customer AWS and on-premises environments, ensuring stability, high availability, and secure connectivity.
• Act as a trusted technical partner, advising customers on cloud, physical, and hybrid network design, optimisation, and integration.
• Take ownership of understanding customer environments, identifying gaps in documentation, and proactively creating and maintaining accurate network diagrams and technical documentation.
• Support IT Naturally’s 24/7 managed service delivery with proactive monitoring, incident response, and continuous improvement.
