  • Experience: 5+ years of experience in web application penetration testing, ideally at a Principal Consultant level or similar.
  • Technical Skills: Strong capability in advanced web application testing, with a background in development, offensive tool creation, and code auditing preferred.
  • Certifications: While CHECK status is not required, relevant certifications such as OSCP, OSWE, OSEP, OSWA, CREST CRT, or CCT App are highly desirable.
  • Remediation Expertise: Proven ability to provide effective remediation advice to developers and system owners.
  • Adversarial Interest: A keen interest in expanding into adversarial simulation, red teaming, and more advanced testing scenarios.
  • UK Work Rights: Must have full and permanent right to work in the UK (UK Nationals or those with ILR). Unfortunately, we cannot offer visa support for PSW or out-of-country applicants.

Why Join Us?

  • Innovative Environment: Be part of a dynamic and growing team, working on exciting projects with real impact.
  • Competitive Package: Up to £100k salary with benefits and flexibility around your work location.
  • Growth Opportunities: Develop your skills in more adversarial roles and explore new avenues in cybersecurity.
