Key Responsibilities
• Design and build security controls for internal GenAI applications, APIs, model usage patterns and platform integrations
• Secure agentic AI, tool-calling and connector-based workflows, including MCP-style integrations and privileged system access
• Lead technical threat modelling across prompt injection, jailbreaks, data leakage, tool abuse, model misuse and AI supply-chain risk
• Define secure reference patterns for cloud-native and hybrid GenAI workloads, including secrets, network boundaries and service isolation
• Build monitoring and detection logic for unusual AI behaviour, unsafe outputs, suspicious tool activity and potential data exposure
• Support response and remediation for incidents involving AI-enabled applications, internal platforms or sensitive information
• Translate AI security requirements into practical engineering controls, evidence, testing and audit-ready documentation
• Act as a technical AI security partner to engineering, infrastructure, MLOps, product, legal, compliance and business stakeholders
What You’ll Bring…
• 5+ years of software engineering, product security, application security or security engineering experience, with strong hands-on coding in Python, Go, Java or similar
• Practical experience with AI/ML or GenAI technologies, ideally including LLM applications, RAG, agents, tool-calling, model APIs or AI platform infrastructure
• Strong understanding of AI security risks, including prompt injection, unsafe tool execution, data exfiltration, jailbreaks, training data leakage and supply-chain exposure
• Experience building, deploying or securing containerised services using Kubernetes
• Ability to design and deliver production-grade security controls without slowing down engineering delivery
• Strong threat-modelling capability across modern software, cloud, API, data and AI-enabled systems
• Experience working with CI/CD, infrastructure pipelines, DevOps, MLOps or platform engineering teams
• Clear communication style, with the ability to influence technical and non-technical stakeholders in a high-performance environment
