Cyber Security Penetration Tester

Reference: 8lcrn8m31pdd39ux8dji

We are seeking a Cyber Security Penetration Tester to assess the resilience of systems, applications, networks and infrastructure against real-world cyber threats. You will plan and conduct authorised penetration tests, vulnerability assessments and security reviews across web applications, APIs, mobile platforms, cloud environments, internal networks and external attack surfaces. The role involves identifying weaknesses, validating their potential impact and providing practical recommendations that help strengthen security controls and reduce organisational risk.

Your responsibilities will include defining test scopes and methodologies, performing reconnaissance, threat modelling and manual security testing, and using appropriate tools to support your assessments. You will investigate and safely exploit vulnerabilities where authorised, document clear evidence, assess risk using recognised frameworks and prepare high-quality technical reports for both technical and non-technical audiences. You will also present findings to stakeholders, explain remediation priorities, support retesting activities and contribute to the continuous improvement of security testing processes, standards and documentation.

Applicants should have hands-on experience in penetration testing, vulnerability assessment or a closely related cyber security role, with a strong understanding of common attack techniques and defensive controls. Practical knowledge of web application, network, API, cloud or mobile security testing is required, along with familiarity with recognised methodologies such as OWASP, PTES, OSSTMM or CREST principles. Relevant certifications such as OSCP, CREST, GPEN, GWAPT or equivalent experience are advantageous. You should be analytical, curious and able to communicate complex technical issues clearly. The successful candidate must demonstrate professional integrity, meticulous attention to detail and a commitment to conducting all testing ethically, safely and within agreed authorisation.
