Elite Offensive Security Consultancy | Advanced Testing | High‑Impact Engagements

I’ve recently partnered with a leading advanced penetration testing consultancy that is expanding its presence into the UK. As part of this growth, they are looking for experienced CHECK certified penetration testers to join their newly forming UK team.

This is not your typical testing role. This consultancy is widely recognised for its deep technical capability, research driven approach, and highly complex offensive security engagements. With increasing demand across the UK, they are building a specialist team of top tier testers who want to work on meaningful, challenging, and genuinely exciting projects.

If you’re a CHECK certified tester who thrives on advanced technical work, autonomy, and pushing the boundaries of offensive security, this is the kind of role that elevates your career.

• Experience delivering high quality testing across multiple domains
• Ability to work autonomously in a senior, trusted capacity
• Strong communication skills and the ability to translate technical findings into real world impact
