About The Position

At Twenty, we're taking on one of the most critical challenges of our time: defending democracies in the digital age. We develop revolutionary technologies that operate at the intersection of the cyber and electromagnetic domains, where the speed of operations exceeds human sensing and complexity transcends conventional boundaries. Our team doesn't just solve problems – we deliver game-changing outcomes that directly impact national security. We're pragmatic optimists who understand that while our mission of protecting America and its allies is challenging, success is possible. Role Summary We are hiring our first IT Manager to build and run the internal IT function at Twenty as we scale. You will own the systems and day-to-day operations that keep employees productive, secure, and supported across devices, identity, collaboration tools, and office technology. This is a hands-on role with real ownership: you will solve immediate operational needs while building the processes, standards, and roadmap for a durable IT function. You will partner closely with leadership, engineering, operations, and security stakeholders in a high-trust environment where reliability, speed, and sound judgment matter. Who You Are You are comfortable owning a function from the ground up and building systems that scale with the company. You balance speed, security, and practicality without creating unnecessary processes. You are equally effective operating hands-on day to day and setting direction for the future. You bring strong judgment around privileged access, endpoint security, and internal systems reliability. You are organized, dependable, and thoughtful when handling sensitive workflows and company-critical systems. You communicate clearly with both technical and non-technical teams. You enjoy creating structure where little exists today and raising the bar as the company grows. You are motivated by supporting mission-critical work in a security-conscious environment.
