operating systems, exploit mechanics, and secure software development. You will drive the
product security vulnerability lifecycle, lead threat modeling and penetration testing strategies
for Arista’s switch architecture, integrate security mechanisms into our software development
lifecycle (SDLC), and ensure our federal cloud environments maintain an aggressive security
posture.
