Top SchoolSusan Hinrichs is a Distinguished Engineer with 11+ years of recent experience building low-level, security-focused networking and systems software, currently driving cloud-native network security at Aviatrix.

Susan has a strong track record of designing distributed firewalls and mandatory security systems across industry and academia, blending hands-on kernel/OS-level work with architectural leadership. Her background includes roles as Chief Scientist and Principal Architect, longtime Apache PMC membership, and teaching computer and network security at UIUC, which reflects both practical delivery and a commitment to mentoring.
