Job Details
Overview
We are seeking a hands-on Principal Software Engineer (Security) with deep expertise in artificial intelligence security to take the lead in securing cutting-edge initiatives in Microsoft Edge. This Redmond-based role focuses on understanding existing and emerging threats, as well as cutting edge defenses, all within the context of a modern web browser. The ideal candidate has a solid background in AI (understanding how large language models work, prompt engineering, grounding techniques, when fine-tuning models is needed). While browser security domain knowledge is desirable, experience and expertise of AI integrations is paramount. This engineer will research new AI-driven vulnerabilities and implement practical mitigations to keep our users safe. The role is highly collaborative and requires excellent communication skills to work with multiple internal groups and external industry partners on securing AI features for modern AI browsers.
This role is about bringing top-tier AI security expertise into a browser security context. We need someone who can think like an attacker to anticipate how AI features could be abused, and act like an engineer to implement safeguards that make our browser and users safer. In doing so, you will elevate the security posture of Edge's AI capabilities and help shape industry-leading practices for securing AI in end-user applications.
Microsoft's mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.
