Anson McCade is proud to be supporting a global innovation and transformation consultancy in growing their elite Digital & Data team. We're seeking a Penetration Tester with a deep focus on infrastructure and Active Directory environments. This isn't your typical web app testing role-this is hands-on, internal infrastructure testing in high-stakes client environments (defence, critical infrastructure, national security).
This is a high-trust, high-impact role for someone confident in navigating sensitive networks, with the ability to think independently, consult directly with clients, and deliver clear, actionable insights.
As a Penetration Tester, you will:
• Deliver internal infrastructure penetration tests, including Active Directory environments
• Act as a trusted advisor to clients-this is a hands-on consulting-facing role
• Document clear, concise technical reports for both technical and non-technical stakeholders
• Operate independently in sensitive and sometimes live production environments
• Contribute to tooling, methodology development, and internal process improvement
• Demonstrate initiative in building and adapting testing approaches to client environments
You'll bring:
• 4+ years' experience in infrastructure penetration testing
• Deep understanding of AD-based attacks, lateral movement, privilege escalation
• Comfort operating in production environments with limited runbooks or documentation
• Strong Windows and Linux command-line skills
• Ability to work with legacy systems and navigate environments with tech debt
Desirable skills & qualifications:
• Python scripting or coding skills (advantageous)
• Exposure to OT networks and internal infrastructure tooling
• Relevant certifications - CREST (CTM, CTL, CSTM), Cyber Scheme Practitioner, OSCP
Work Environment & Expectations:
• Join a tight-knit, high-performing team
• Hybrid model: ~2 days per week in client or office locations, majority remote
• Primary base in London preferred, though other UK locations are possible based on flexibility
Security Clearance:
• Must be SC clearable
• Current SC clearance highly desirable
Salary & Package:
• £70,000 to £95,000 (DOE, Various levels available)
• Package + bonus, pension, and private healthcare
