Our client is looking for an experienced cybersecurity professional who understands how modern Security Operations Centres (SOCs) should operate – not just how they've always been done.

This is an chance to help organisations transform their security operations using Cortex technologies, including XSIAM, by combining deep technical expertise with strong consulting and stakeholder engagement skills.

You will work closely with customers to understand their environments, design practical solutions and lead the successful delivery of complex security platforms that improve visibility, automation and threat detection.

If you've spent years working across SIEM, SOC, security engineering and DevOps – and enjoy solving difficult technical problems while working directly with clients – we'd love to hear from you.

What you'll be doing

You will work across the full delivery lifecycle, including:

- Designing and delivering Cortex security solutions, particularly Cortex XSIAM.
- Working directly with customers to understand business requirements and translate them into practical technical solutions.
- Leading technical workshops and architecture discussions with both technical and executive stakeholders.
- Designing security monitoring, detection and response capabilities
- Integrating multiple security technologies into a unified security operations platform.
- Developing and improving security automation, orchestration and operational workflows.
- Working alongside engineering teams to deploy and optimise cloud and hybrid security environments.
- Applying DevOps practices to improve deployment,



scalability and operational efficiency.
- Providing technical leadership throughout implementation and delivery
- Supporting customers as they mature their SOC capabilities and security operations processes.
- Producing high-quality architecture documentation, solution designs and implementation guidance.

What we're looking for

You will ideally bring experience across most of the following:

- Extensive experience designing or delivering enterprise cybersecurity solutions.
- Strong background working within Security Operations Centres (SOC).
- Significant hands‑on SIEM experience, with Cortex XSIAM highly regarded.
- Experience with security automation, orchestration and response technologies.
- Strong understanding of modern detection engineering and incident response practices.
- Experience integrating multiple security tools and platforms.
- Solid DevOps experience, including CI/CD, Infrastructure as Code and automation.
- Experience working within large enterprise or telecommunications environments.
- Strong consulting skills with the ability to engage confidently with customers and stakeholders.
- Excellent communication skills and the ability to explain complex technical concepts in plain language.




- A collaborative approach and passion for solving customer problems.

Highly regarded

Experience with any of the following would be advantageous:

- Cortex XSIAM
- Cortex XSOAR
- Cortex XDR
- Splunk
- Microsoft Sentinel
- QRadar
- Elastic
- AWS
- Google Cloud
- Terraform
- Docker
- Python
- PowerShell
- REST APIs

Why you'll enjoy this role

This is far more than a traditional architecture position. You will work at the forefront of modern security operations, helping organisations replace legacy approaches with intelligent, automated security capabilities that improve resilience against increasingly sophisticated cyber threats. You will collaborate with highly skilled engineers, architects and security specialists on complex enterprise environments where your expertise will directly influence technical strategy and customer outcomes. If you enjoy combining architecture, engineering, automation and customer engagement into one challenging role, you’ll find plenty to keep you interested.

About you

You’re someone who enjoys understanding how complex systems fit together and can see the bigger picture while still diving deep into the technical detail. You’re equally comfortable discussing architecture with senior executives, whiteboarding solutions with engineers, or troubleshooting technical challenges alongside delivery teams. Most importantly, you’re motivated by solving real customer problems and delivering solutions that make a measurable difference.
