Our role:
As an Executive Principal Consultant within the Red Teaming practice, you’ll take a leading role in delivering high-end adversary simulation engagements for clients with mature security postures and critical risk profiles. You'll operate across the entire attack lifecycle from initial access and evasion of EDR, through lateral movement and objective completion while ensuring the safety, confidentiality, and operational integrity of every engagement.

This role is central to advancing NCC Group’s offensive security capability while helping our clients understand, detect, and respond to sophisticated threats in real-world scenarios.

You’ll lead the design, planning, and execution of Red Team and adversary simulation engagements across critical sectors such as financial services, government, and defence. These operations will align with frameworks such as CBEST, TIBER, CORIE, and more. You’ll also build strong relationships with C-level stakeholders, lead debriefs with both technical and executive audiences, and translate complex attack paths into clear, actionable insight.

Over the next 6-12 months, you'll establish yourself as a senior authority in the Red Teaming space, contribute to tooling and methodology development, mentor rising talent, and play an active role in growing our capability in both regulated and bespoke assessments. You’ll also contribute to our capability development and mentor the next generation of Red Teamers.

• Report writing that balances narrative flow and technical accuracy
• Familiarity with CBEST, TIBER, CORIE, AASE, iCAST, FEER
• Current CCSAM (or equivalent) qualification. However, if you hold CCSAS and want to pursue the CCSAM route, we are keen to support you in your venture
• CREST CCT-INF is desired
• Experience building tools or automation for Red Team use.
