Sr. Applied Scientist, Enterprise Security Products

What happens when you combine startup speed with Amazon-scale innovation and impact? You get this team. Amazon Enterprise Security Products is a newly launched group building intelligent, cloud-agnostic security tools using AI-first development practices. Here, you don"t just publish papers about what"s possible, you ship it to production and watch it protect real customers. This role offers a rare opportunity to define the scientific direction of a greenfield security portfolio, where agentic AI, foundation models, and novel ML approaches aren"t future bets, they"re what we"re building right now. It"s a chance to shape the future of security tooling with a small, fast team that researches like a lab and deploys like Amazon.

Key job responsibilities

• Set the science vision: Define a multi-year science roadmap for AI-powered security products. Identify where foundation models, agentic systems, and emerging ML techniques can fundamentally change how we detect, prevent, and respond to threats protecting Amazon Business customers.
• Invent and build, end to end: Design and personally develop novel ML solutions - from agentic architectures and RAG systems to anomaly detection and behavior modeling. You won"t hand off prototypes; you"ll partner with engineers and PMs to ship them into production.
• Tackle scientifically ambiguous problems: Translate messy, open-ended security challenges into well-defined scientific problems. Own the critical novelty in our systems and provide system-wide design guidance.
• Experiment with rigor and speed: Design and run offline and online experiments to validate ideas quickly. Make data-driven calls on what ships, what iterates, and what gets killed.
• Push the frontier: Stay ahead of advancements in foundation models, agentic AI, and applied ML. Evaluate emerging capabilities and make strategic build-vs-buy decisions. Publish your work at top conferences when it advances the field.
• Influence across the org: Partner with security researchers, engineers, product managers, and UX designers to turn customer needs into technical strategy. Communicate complex scientific ideas clearly to both technical and executive audiences.
• Raise the bar: Mentor applied scientists and engineers, establish scientific review practices, and set the standard for how this team does science. This is a ground-floor opportunity to shape the culture.
• Innovate with urgency: Prototype rapidly, validate with customers, and iterate. Bring a builder-scientist mindset to an environment where the best idea wins.

A day in the life

You lead from the front on a startup-paced, AI-first development team. One moment you"re whiteboarding a new agentic detection architecture with principal engineers, the next you"re deep in a notebook training a model or analyzing experiment results. You author science vision docs, drive design reviews, and unblock your team when the problem space gets murky. You don"t just track the latest in AI, you decide what"s worth betting on and lead the team in making those bets real. Every day you"re advancing the science and advancing the product.
