The Role

Join us as a Senior Network Security Consultant / Architect

We are looking for an experienced Network Security Consultant / Architect who enjoys solving complex technical challenges and working closely with customers to build secure, resilient network environments.

This is not a purely architectural role. We are looking for someone who can move comfortably between architecture, design and hands-on implementation , whether that means designing a new network security architecture, migrating firewall environments or troubleshooting a complex customer issue.

You will work across different customer environments and be trusted to take technical ownership, advise stakeholders and turn requirements into solutions that work in practice.

What you’ll be doing

Depending on the customer and assignment, you will:

Design and implement secure enterprise network architectures

Work hands-on with Cisco Networks, Palo Alto Networks, Fortinet/FortiGate and related security technologies

Design and perform firewall migrations and security improvements

Implement network segmentation and micro-segmentation

Support OT network segmentation and security

Design Zero Trust network architectures

Work with routing, switching, VPN and secure remote access

Troubleshoot complex network and security issues

Design hybrid and cloud-connected network environments

Perform network hardening and security improvements

Produce clear technical designs and documentation

Act as a trusted technical advisor to customers

In short, you should be comfortable taking an engagement from:

Requirements → Architecture → Design → Implementation → Troubleshooting → Documentation

What we’re looking for

We believe you have several years of experience within enterprise networking and network security, ideally 7+ years , and that you are comfortable working independently in complex customer environments.

You have strong experience in several of the following:

Palo Alto Networks, including NGFW, Panorama and VPN

Fortinet / FortiGate

Enterprise network security

Firewall architecture, implementation and migration

Network segmentation and micro-segmentation

Routing and switching

VPN and remote access

Network troubleshooting and performance

Security architecture and solution design

Network hardening

Hybrid/cloud networking

Nice to have

Experience with any of the following is a strong advantage:

Zscaler, SASE or SSE

Prisma Access

Microsoft Azure networking and security

AWS networking and security

Cisco networking

F5

SD-WAN

OT security

Regulated or critical infrastructure environments

Certifications such as PCNSE, Fortinet certifications, CCNP/CCIE Security, Azure or AWS certifications are valuable, but practical experience and technical depth matter most.

The kind of person we think will thrive

You enjoy being close to the technology and solving difficult problems, but you can also step back, understand the bigger picture and explain your recommendations to customers.

You don't want to choose between being an engineer and an architect. You want to be able to do both.

If that sounds like you, we’d like to hear from you.
