Full Time

Are you ready to take ownership of a critical network environment and help shape the future of IT infrastructure in a collaborative, forward-thinking team? We’re looking for a Network Engineer who thrives on solving complex challenges, enjoys working across infrastructure and security domains, and is excited to contribute to a high-performing, close-knit team.

This is more than just a technical role — it’s an opportunity to bring your ideas to life, influence how we evolve our network, and play a key part in delivering secure, resilient, and scalable solutions that support the entire business.

What you’ll do

* Manage and optimise network infrastructure, including virtual networks, cloud infrastructure, and WAN technologies.

* Configure and maintain firewalls, routers, load balancers, and switches.

* Deploy security and operational updates in line with business guidelines.

* Monitor network performance and resolve bottlenecks.

* Collaborate with infrastructure and security engineers to align on requirements.

* Support and educate helpdesk staff on network-related issues.

* Participate in out-of-hours work as required by the role.

What we’re looking for:

* Advanced knowledge of networking (TCP/IP, subnetting, VLANs, VPNs, load balancing).

* Strong troubleshooting and analytical skills.

* Experience with FortiNet firewalls and Cisco switches (including CLI configuration).

* Proficiency in Linux and Windows operating systems and Aws & Azure.

* Experience with backup and disaster recovery solutions.

* Familiarity with implementing Cisco security and firmware updates. Ability to work cross-functionally and communicate technical concepts clearly.

Why Join Us?

* Make a Real Difference: Your work will directly impact the security, performance, and resilience of our business-critical systems.

* Collaborative Culture: Join a supportive team that values knowledge sharing, continuous learning, and mutual respect.

* Growth Opportunities: We invest in your development — whether that’s through certifications, hands-on experience, or exposure to new technologies.

* Work-Life Balance: We understand the importance of flexibility and offer a working environment that supports your wellbeing.

* Innovation Encouraged: We welcome fresh ideas and give you the space to innovate and improve how we do things
