Responsibilities

• Conduct Structured Testing to Identify Security Vulnerabilities:
  • Demonstrate a functional understanding of modern attack vectors and penetration testing software, and be technically capable of using them to identify security vulnerabilities in Web applications, APIs and network infrastructure.
  • Consistently complete assigned penetration tests within allocated timeframes, in accordance with our methodologies.
• Continuous Learning:

• Working Hours:
  • Be able to execute testing within UK core business hours (09:00 - 17:30 GMT). Some tests may fall outside of these hours, but the majority of tests will need to be completed within this timeframe.

Desired Skills & Experience

• Experience: 6+ months as a penetration tester (or equivalent demonstrable experience) with a foundational understanding of wider cybersecurity concepts and best practices.
• Technical Skills: Familiarity with commonly used security testing tools (e.g. BurpSuite, Nmap) and approach to penetration testing activities.
• Soft Skills:
  • Strong desire to learn, good communication skills for peer and mentor interactions, and the ability to follow instructions.
  • Strong written and spoken business English (C1+ or native fluency).

• Our team consists of a broad range of people: musicians, adventure sports junkies, nature lovers, parents, cereal enthusiasts, night owls, cyclists, artists—you get the point.
