Senior Network Security Consultant

We’re working with a growing specialist network and connectivity business that designs, builds and supports complex network environments for large organisations across the UK. Due to continued growth, they’re looking to add a Senior Network Security Consultant to the team.

This is much more than a 3rd line support position. You’ll take projects from initial customer requirements and solution design through to implementation, documentation and ongoing technical ownership.

You’ll work closely with customers and the commercial team at the pre-sales stage, gathering requirements, designing solutions and presenting those back to the customer before taking the technical lead through delivery.

It’s a genuinely hands-on consultancy position, but one where you’ll have much more ownership around architecture, customer strategy and technical direction.

There’s a strong investment in technical development too, with relevant professional qualifications and certifications funded as part of the role.

Day to day

You’ll be designing, implementing and supporting network security solutions across complex customer environments.

That will include enterprise firewalls, LAN/WAN, VPNs, SD-WAN, ZTNA, SASE, authentication and wider network security technologies, alongside maintaining a strong understanding of routing, switching and networking fundamentals.

You’ll lead technical projects throughout their lifecycle, producing detailed designs and implementation plans before taking responsibility for successful delivery.

There’s also an increasing focus on modern security operations, so exposure to areas such as SIEM, SOAR and XDR would be useful.

Beyond project delivery, you’ll act as a senior technical escalation point, carry out customer security audits and health checks, make recommendations around improving existing environments and provide ongoing technical ownership for nominated customers.

You’ll also help develop other engineers within the team through technical mentoring, knowledge sharing and internal training.

The environments are business-critical, so there is an out-of-hours/on-call element to the role alongside occasional planned maintenance., The role can be based remotely, with occasional travel when needed for customer projects and meetings.

You could currently be a Senior Network Security Engineer, Network Security Consultant, Senior Network & Security Engineer or already operating at Network Security Architect level.

The important thing is that you’ve moved beyond simply supporting network environments. You’ll have experience designing solutions, leading implementations and taking technical ownership of customer projects.

We’re looking for strong networking fundamentals alongside detailed experience across enterprise firewalls, LAN/WAN, VPN, SD-WAN and modern network security architecture.

Experience within an MSP, ISP, network integrator or consultancy would translate particularly well, particularly if you’re used to working across multiple customers and complex environments.

You’ll need to be comfortable gathering requirements, producing technical designs, presenting solutions to customers and then remaining involved through implementation and ongoing support.

Experience around security compliance frameworks and public-sector environments would be useful, as would exposure to SIEM, SOAR, XDR and infrastructure automation.

More than anything, they want somebody who can take technical ownership. Someone who can get into the detail when needed, communicate confidently with customers and be the person other engineers turn to when things get complicated.
