AI Security Engineer (Application Security)
Playtech's Security unit is looking for a proactive AI Security Engineer (Application Security) with excellent communication and problem-solving skills. You'll be part of the Application Security team, doing the security engineering work the team is known for, with a focus on the AI-powered features and systems the company builds.
Your influential mission. You will perform threat modelling and security design reviews for applications, with a focus on AI and LLM-powered features. You will work closely with security, engineering and data science teams to identify, analyse and mitigate security vulnerabilities. You will review the security of AI application architecture, including RAG pipelines, agent and tool-calling flows, model APIs and integrations. You will test AI features adversarially for prompt injection, data leakage, jailbreaks and unsafe output handling. You will define guardrails, input and output validation, and monitoring for AI systems. You will help build secure-by-default patterns and guidance so teams can ship AI features safely. You will support development by using commercial and open source security technologies. You will track the evolving AI threat landscape and translate it into practical standards for our teams.
