Role Summary The AI Security Engineer is responsible for securing the enablement and use of AI, GenAI, LLM, and agentic technologies across the enterprise, balancing business velocity with protection of Applied Materials’ intellectual property, sensitive data, and customer trust. This role drives AI security governance, risk management, technical guardrails, and operational oversight for AI systems and AI‑integrated applications across the full lifecycle—from intake and design through deployment, monitoring, and incident response. The role serves as a key focal point for AI security execution in the US and partners closely with global counterparts and cross‑pillar security teams to deliver scalable, measurable, and auditable AI security controls. Key Responsibilities Technical Mindset & Operating Style Highly technology‑savvy and continuously current on rapidly evolving AI/LLM platforms, agent frameworks, developer tooling, and emerging attack techniques through hands‑on experimentation and learning. Brings strong engineering intuition through prior software development experience or equivalent hands‑on technical background, enabling effective architecture reviews, threat modeling, and pragmatic security guidance. Comfortable reading, writing, and reviewing code (e.g., Python, TypeScript, or similar) to understand AI workflows, model integrations, APIs, pipelines, and real‑world failure modes. Practical experience experimenting with AI tooling, copilots, agents, and “vibe‑coding” workflows, with an understanding of how developers’ prototype, iterate, and ship AI‑enabled systems. Able to translate modern developer behaviors (prompt‑driven development, agent orchestration, rapid iteration) into realistic, enforceable security controls rather than theoretical policy. Uses technical credibility to influence engineering teams, accelerate adoption of secure AI patterns, and ensure security enables—rather than blocks—innovation.
