Key skills for this role
We are seeking IT Security Engineer to join our growing technology engineering team. This is a critical role that will establish and maintain our security infrastructure, protect our digital assets, and ensure compliance with industry standards. You will be responsible for implementing comprehensive security solutions across our network, systems, and applications, while working closely with our development and operations teams to embed security into our organizational culture.
America is under sustained cyber attack. Our adversaries infiltrate our networks, steal our IP, and degrade the digital infrastructure that modern life runs on. They’ve learned—correctly—that those attacks rarely produce consequences.
Twenty was founded to change that, by making our adversaries think twice before they attack us. Our vision is American and allied primacy in cyberspace—a future where they cannot contest us, deterrence is assured, and the free world remains secure.
Founded in 2024, Twenty Technologies ( www.twenty.io ) industrializes offensive cyber operations for the U.S. and its allies. Headquartered in Arlington, Virginia, Twenty has raised $138M from Accel, Caffeinated Capital, Friends & Family Capital, Point72 Ventures, General Catalyst, and In-Q-Tel.
