Cyber Security Engineer

🚨 Lead Security Engineer | London | Hybrid (4 days in office) | £90,000–£110,000

I'm working with an exciting technology business looking to hire a Lead Security Engineer who wants to take ownership of security rather than simply advise on it.

This is a genuinely hands-on leadership opportunity where you'll become the organisation's senior security authority, working directly with the CIO to shape security strategy while rolling up your sleeves to build, improve and operate security controls.

You'll be responsible for:

🔹 Owning and evolving the security architecture across cloud, application, network and data security

🔹 Driving security across AWS environments and DevSecOps practices

🔹 Building and tuning Microsoft Sentinel into a mature detection and response capability

🔹 Working closely with engineering teams to embed security into CI/CD pipelines

🔹 Leading incident response and continuously improving the organisation's security posture

🔹 Helping shape AI security governance as the business continues to adopt modern AI technologies.

What they're looking for:

✔ Hands-on Security Engineering or Security Architecture experience

✔ Microsoft Sentinel expertise (or strong SIEM experience)

✔ Deep AWS security knowledge

✔ Experience with the Microsoft security stack (Defender, Entra ID & Purview)

✔ DevSecOps and CI/CD security experience

✔ Someone who enjoys solving technical problems and can communicate effectively with both engineers and senior stakeholders.

What's on offer?
