Cybersecurity Tester/Researcher
We are seeking a Cybersecurity Tester/Researcher to assess the security of applications, infrastructure, networks, and emerging technologies. The successful candidate will plan and conduct penetration tests, vulnerability assessments, security reviews, and controlled attack simulations across web, mobile, cloud, API, and enterprise environments. You will identify weaknesses, validate their impact, and provide clear, evidence-based recommendations that help strengthen security controls and reduce operational risk.
Responsibilities include defining test scope and methodologies, performing manual and automated security testing, researching new vulnerabilities and attack techniques, developing proof-of-concept exploits where appropriate, and analysing security events or suspected compromises. You will document findings in detailed technical reports, prioritise issues according to likelihood and business impact, and present results to both technical and non-technical stakeholders. The role also involves maintaining testing tools and scripts, contributing to threat modelling and security standards, supporting remediation activities, and staying informed about developments in offensive security, vulnerability research, cloud technologies, and regulatory expectations.
Applicants should have practical experience in penetration testing, vulnerability research, application security, or a closely related cybersecurity discipline. Strong knowledge of common attack methods, network protocols, operating systems, authentication mechanisms, secure coding principles, and security testing frameworks is required. Experience with tools such as Burp Suite, Nmap, Metasploit, Wireshark, or equivalent technologies is desirable, as is proficiency in scripting or programming languages such as Python, PowerShell, Bash, or JavaScript. Professional certifications including OSCP, CREST, GPEN, GWAPT, or comparable qualifications are advantageous. You should demonstrate sound analytical judgement, careful attention to detail, strong written and verbal communication skills, and the ability to work independently while collaborating effectively with wider technical teams. All testing must be conducted responsibly, ethically, and in accordance with agreed authorisation and data-handling requirements.
