Horizon3.ai is offering SkillBridge opportunities for transitioning service members to gain hands-on experience in offensive cybersecurity and autonomous penetration testing. Participants will work with the NodeZero platform, a production-safe autonomous penetration testing system used by organizations ranging from educational institutions to government agencies and Global 100 enterprises. This program provides real-world experience in cutting-edge cybersecurity technology, working alongside a team that includes former U.S. Special Operations cyber operators and industry veterans. Training emphasizes Python development, vulnerability research, exploit development, and offensive security automation—highly transferable skills for civilian cybersecurity careers.

The Attack Engineer role focuses on developing and maintaining offensive security capabilities within NodeZero's automated penetration testing platform. In this position, participants will write Python-based attack modules that simulate real-world adversary tactics, research emerging vulnerabilities and exploitation techniques including 1-day exploit development and reverse engineering, and develop automated exploit chains and attack workflows. The role involves close collaboration with the engineering team to integrate new attack capabilities into production, as well as testing and validating attack scenarios in controlled environments. Attack Engineers contribute to platform architecture and data models, monitor threat intelligence sources and vulnerability databases for emerging threats, and document research findings while creating technical content to showcase their work.Candidates should possess strong Python development skills and a solid understanding of network protocols and system architecture. Knowledge of common vulnerabilities, particularly those documented in the OWASP and MITRE ATT&CK frameworks, is essential. The role requires the ability to write secure, maintainable code that performs offensive security operations at scale. Military cyber operations or security experience is strongly preferred and will provide valuable context for the offensive security mindset required in this position.
