Junior Penetration Tester (audit)
We are seeking a Junior Penetration Tester to support security assessments across web applications, infrastructure, cloud environments and internal networks. Working as part of an experienced audit and testing team, you will help identify vulnerabilities, validate security controls and provide clear, practical recommendations to improve clients’ security posture. This role is suited to someone at the beginning of their penetration testing career who is keen to develop technical expertise within a structured, professional environment.
Your responsibilities will include assisting with scoping and preparing penetration tests, conducting reconnaissance and vulnerability assessments, and supporting the exploitation of identified weaknesses under controlled conditions. You will document evidence accurately, maintain detailed testing notes and contribute to professional, risk-based reports. You may also participate in remediation reviews, retesting activities and client meetings, explaining technical findings in a clear and constructive manner. All testing must be performed ethically, safely and in accordance with agreed rules of engagement, relevant standards and applicable legislation.
Applicants should have a foundational understanding of networking, operating systems, web technologies and common information security principles. Familiarity with tools such as Burp Suite, Nmap, Nessus, Metasploit, Kali Linux or comparable security testing platforms is desirable, as is an awareness of OWASP guidance and penetration testing methodologies. Strong analytical, written and verbal communication skills are essential, along with careful attention to detail and the ability to manage competing priorities. Relevant study, practical laboratory experience, security certifications or demonstrable personal projects will be welcomed. You should be curious, willing to learn, comfortable receiving feedback and committed to maintaining professional integrity and confidentiality. A willingness to undertake occasional travel or work flexibly to meet assessment requirements may also be necessary.
