  • Communicate high-risk vulnerabilities to clients as they are identified, supporting swift remediation.
  • Support junior team members and assist with quality assurance on reports where required.
  • Assist with the maintenance of internal penetration testing infrastructure, including device setup and tooling updates.
  • Stay up to date with the evolving threat landscape, contributing to internal knowledge sharing and continued team development.

Requirements:

  • CHECK Team Member (CTM) status, or actively working towards CREST Registered Tester (CRT) on the CREST pathway.
  • Hands-on experience delivering web application, API, and/or infrastructure penetration tests in a professional setting.
  • Strong understanding of common vulnerability classes (e.g. OWASP Top 10), exploitation techniques, and remediation guidance.
  • Confident client-facing communication skills, with the ability to explain technical findings to both technical and non-technical audiences.
  • Strong written reporting skills, with the ability to produce clear, well-structured deliverables.
  • A genuine passion for offensive security, demonstrated through CTFs, labs (e.g. Hack The Box, TryHackMe), research, or community involvement.
