Senior Network Architect
Are you a network architecture expert who thrives on designing secure, scalable, and resilient solutions across complex environments? We’re looking for a Senior Network Architect to lead the design and governance of enterprise network architectures.
You’ll play a key role in shaping and delivering robust network solutions that align with organisational strategy, security standards, and operational requirements. Working within a multi-vendor environment, you’ll collaborate with technology, security, and business stakeholders to influence decisions and drive best practice.
We can offer great career progression opportunities, ability to be based anywhere across the UK, benefits which you can flex to meet your needs, and training and development opportunities.
What you'll be doing:
- Lead the design and documentation of end-to-end network architectures across campus, data centre, WAN, WLAN, and cloud environments.
- Produce High Level Design and low-level design artefacts, standards, patterns, and reference architectures.
- Architect solutions across multi-vendor technologies including Cisco, Meraki, Aruba, Check Point, Fortinet, and Palo Alto.
- Develop secure network architectures incorporating segmentation, firewalling, Zero Trust principles, and best-practice security controls.
- Design and integrate SD-WAN solutions and collaborate with cloud teams to deliver hybrid and cloud-connected architectures (Azure/AWS).
- Provide technical governance, design assurance, and act as a senior escalation point while supporting vendor selection and mentoring engineers.
