Summary
🤩
Rockstar🎓
Top SchoolJoris De Gruyter is a senior offensive security engineer specializing in AI red teaming at Microsoft, with a decade of experience blending consulting, development, solution architecture, and program management. He has progressed through engineering and leadership roles across Microsoft’s developer productivity and Power Platform teams, bringing deep practical knowledge of developer tools, low-code languages, and enterprise Dynamics platforms. His current work probes AI systems like an attacker—focusing not only on security vulnerabilities but on emergent failures such as prompt injection and ungrounded or harmful content. Comfortable switching between hands-on engineering and cross-functional program leadership, he leverages a long history of building and improving developer tooling, CI/CD, and upgrade workflows. Based in the Greater Seattle Area but educated in Belgium, he pairs European engineering roots with large-scale cloud and product experience at Microsoft. An early web and Dynamics developer, he retains a pragmatic affinity for building robust, auditable solutions that scale from team processes to AI system safety.
