Commit in Toronto, Canada is seeking a senior, hands-on Application Security Researcher to push up-to-date AppSec forward—working with engineers, researchers and AI/data scientists on next-generation detection, including autonomous, agentic pen-testing capabilities. This is a build-and-break role, not a typical AppSec position. This role focuses on practical security research, delivering production-grade Python/Go code, tuning detection logic, and communicating attack paths clearly to product teams.
