Senior Penetration Tester
We are seeking an experienced Senior Penetration Tester to assess the security of complex applications, infrastructure, networks, cloud environments, and connected technologies. You will plan and deliver penetration tests across web and mobile applications, APIs, internal and external networks, wireless environments, and adversary simulation engagements. The role involves identifying vulnerabilities, validating their potential impact, demonstrating realistic attack paths, and providing clear, actionable recommendations that support effective remediation.
You will lead engagements from scoping and rules of engagement through reconnaissance, testing, exploitation, evidence collection, and reporting. Responsibilities include developing test plans, selecting appropriate tools and methodologies, conducting manual assessments beyond automated scanning, and communicating findings to both technical and non-technical stakeholders. You will produce high-quality reports that explain business risk, affected assets, reproduction steps, severity, and practical remediation guidance. You may also support retesting activities, security architecture reviews, threat modelling, and the development of internal testing methodologies, tools, and knowledge-sharing materials. The role may include mentoring junior testers and contributing to continuous improvements in assessment quality and delivery.
Applicants should have substantial professional experience in penetration testing, offensive security, or a closely related discipline, with a strong understanding of common vulnerabilities and attack techniques. Demonstrable expertise in areas such as OWASP testing, network exploitation, authentication and authorisation weaknesses, privilege escalation, cloud security, scripting, and secure communications is required. Relevant industry certifications, such as OSCP, CREST, GPEN, GWAPT, or equivalent practical experience, are advantageous. You should be comfortable using tools such as Burp Suite, Nmap, Metasploit, and industry-standard vulnerability assessment platforms, while relying on sound manual testing and analytical judgement. Strong written and verbal communication, careful documentation, professionalism, and the ability to manage multiple engagements independently are essential. Applicants must be eligible to complete any required background screening and work responsibly within defined legal and ethical boundaries.
