We pride ourselves on our customer service, forward-thinking approach, and commitment to excellence. Our small but mighty team works with some of the best-known companies in the world, covering over 30 countries worldwide!
About the Role
As a Penetration Tester, you’ll deliver security assessments across networks, applications, APIs, mobile, and cloud environments. Using a mix of automated tools and manual techniques, you’ll simulate real-world attack scenarios to uncover vulnerabilities and help clients improve their security posture.

Key Responsibilities
- Conduct penetration tests across networks, web apps, APIs, mobile apps, and cloud environments.
- Simulate real-world attacks to assess client resilience.

Requirements
- Hands-on experience with penetration testing, vulnerability scanning tools, and offensive security techniques.
- Strong technical skills and the ability to explain complex vulnerabilities to non-technical stakeholders.
- Industry certifications such as OSCP, CRT, CPSA, or equivalent are desirable but not essential.
- Excellent communication and client engagement skills.
If you think you can deliver but don't match the criteria above, please don't be put off. We are very open-minded and focus on ability and attitude above skills.
