We're looking for an Application Security Engineer II to help secure Amplitude's emerging AI-powered features, from chatbots to agentic systems. This role is ideal for a security engineer who loves working at the intersection of AI, application security, and product development; someone who can threat model novel attack surfaces, partner with engineers to design safer systems, and build guardrails that make secure innovation easier. You'll work closely with developers, AI product teams, and security peers to evaluate risks in AI-driven features (such as LLM-based assistants, connectors, and agent integrations), guide secure design, and implement automated defenses across the stack. This is a hands-on role where you'll help shape how we approach security for AI features at scale. You won't just report issues, you'll help fix issues and make it easier for others to avoid them.
