Accounting Manager (First Hire)

About the Company

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.

Role Summary

We are seeking the first full-time Accounting hire on our growing Finance and Operations team. This role is central to our core business operations, focused on establishing and managing efficient and audit-ready financial processes. You will own the foundational financial workflows essential for a high-growth software company, managing today’s business requirements while anticipating the requirements for scale.

This role will be of high interest to candidates with Big 4 (or equivalent) audit experience, high-growth startup accounting experience, and a passion for or interest in the defense technology and cybersecurity industries.

Own Accounting and Financial Operations: Own accounting functions, from annual to day-to-day workflows, ensuring accuracy, efficiency, and timeliness.

Build for Scalability: Identify, propose, and implement solutions to automate and optimize processes. Work with our team to maintain (or reduce) overhead requirements, even as transaction volumes double or triple.

Ability to Prioritize: You understand the operational realities of a high-growth startup, knowing when speed must beat perfection.
