Job description

I’m currently working on an exciting opportunity for an experienced Red Team / Offensive Security professional to join a growing capability within a major UK Defence organisation.

This is not just a traditional penetration testing role.

You’ll be involved in Red Team operations, adversary simulation and threat-led security assessments, helping to replicate realistic attacks against complex, high-assurance environments.

What you’ll be doing:

• Red Team & adversary simulation
• Threat-led security assessments
• Offensive security tooling & automation
• Helping shape Red Team methodologies and capability
• Working directly with customers across Defence & Government environments

What I’m looking for:

• Strong hands-on Red Team / Offensive Security experience
• Experience with adversary simulation or advanced penetration testing
• Experience across areas such as AD, cloud exploitation, C2, detection evasion or exploit development
• Relevant offensive security certifications are advantageous — OSCP, OSEP, OSED, OSCE, CREST, RTO/RTO2 or equivalent
• Defence, Government or other high-assurance experience would be highly desirable
• DV clearance or the ability to attain DV

This is a particularly interesting opportunity for someone who wants to do more than deliver assessments - you’ll have the opportunity to help build and shape a growing Red Team capability.

If you're an experienced Red Teamer, Offensive Security Consultant or Adversary Simulation specialist and this sounds relevant, I'd be interested in having a confidential conversation.
