Threat Modeling Automation Lead

Join our team as a Principal Security Engineer - Threat Modeling Automation Lead on a 12+ month contract. This hybrid role requires three days onsite and combines hands-on application security, threat modeling, AI/LLM-enabled automation, and security engineering at enterprise scale. This role can sit in Charlotte, NC, Irving, TX, Minneapolis, MN, Chandler, AZ or Columbus, OH (hybrid, 3 days on-site).

This is a senior individual-contributor role for an engineer who wants to stay hands-on while setting the technical direction for threat modeling. You’ll tackle complex threat models, build automation that improves delivery at scale, and help advance Continuous Threat Modeling across a large application portfolio.
