AI Security Tester - Technology - Full-time
We are seeking an AI Security Tester to assess the resilience, safety and reliability of artificial intelligence systems across the technology landscape. In this role, you will design and execute structured security assessments against machine learning models, generative AI applications, data pipelines, APIs and supporting infrastructure. You will investigate potential weaknesses including prompt injection, jailbreaks, data leakage, insecure model configurations, training data exposure, adversarial inputs, excessive permissions, supply-chain risks and misuse of AI-enabled functionality.
You will develop realistic test scenarios, threat models and abuse cases, combining established penetration-testing techniques with AI-specific attack methods. Responsibilities include reviewing technical designs, analysing model and application behaviour, creating repeatable test scripts, validating findings, assessing business impact and documenting clear remediation recommendations. You will work closely with engineering, architecture, risk and governance teams to communicate results to both technical and non-technical stakeholders. The role may also involve contributing to security standards, testing frameworks, red-team exercises, continuous monitoring approaches and the evaluation of new AI tools and technologies.
The successful candidate will have experience in application security, penetration testing, red teaming, software engineering or a related discipline, together with a strong understanding of modern AI and machine learning concepts. Practical knowledge of large language models, model evaluation, cloud platforms, APIs, Python or similar scripting languages, and common security testing tools is highly desirable. You should be confident interpreting technical evidence, prioritising risk and presenting concise, actionable findings. Curiosity, ethical judgement, analytical thinking and the ability to work independently are essential. Relevant professional certifications in cybersecurity, cloud security, application security or AI risk are advantageous, as is experience with secure development practices, threat modelling and regulatory expectations for responsible AI.
