Engineer - AI Security

The Role

Exelixis is looking for an AI-forward engineer to bridge the gap between conceptual AI and enterprise-grade automation. You will be responsible for designing and deploying autonomous agents that streamline business workflows, moving rapidly from initial prototypes to hardened, production-ready code. This role isn't about traditional manual labor; it's about using natural language and structured prompts to build scalable IT solutions.

Your AI-Native Toolkit

You will be at the cutting edge of the 'vibe coding' movement, utilizing a modern stack designed for maximum efficiency:

• Coding Agents: Daily use of Claude Code, GitHub Copilot, and Codex to accelerate development.
• Agentic Frameworks: Building multi-step loops and tool-use applications within the AWS and Databricks ecosystems.
• Languages: Rapid prototyping and production work primarily in Python and TypeScript.
• Automation: Managing CI/CD pipelines and automated testing to ensure your AI-generated code meets rigorous security standards.

Why Join This Team?

Located in Alameda, CA, this position offers the chance to define how a major organization adopts responsible AI. You will work in a collaborative environment that prioritizes secure-by-design principles while giving you the freedom to explore the latest AI-assisted development methodologies. It is an ideal environment for developers who want to lead the transition from manual coding to agent-orchestrated engineering.
