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 $168M from Khosla Ventures, Accel, Caffeinated Capital, Friends & Family Capital, Point72 Ventures, General Catalyst, and In-Q-Tel.
Mission | On Site | Full Time | U.S. Citizenship Required / No Active Clearance Required
You'll own the frontend architecture for mission-critical operator experiences—building high-performance interfaces that visualize complex cyber operation data in real time. You'll lead technical direction for UI systems, set the bar for engineering quality, and mentor engineers to move faster with confidence. You'll partner closely with backend, product, design, and operational stakeholders to ship capabilities that must work reliably in both cloud and on-premises environments. You'll be embedded in a cross-functional team building capabilities that go directly into operational use — small team, tight feedback loops, real consequences.
