We're looking for someone with 6-8 years of deep technical expertise in offensive cyber operations, software development, and research, combined with proven leadership experience mentoring engineers and driving strategic technical initiatives. In this role, you'll architect and lead the development of advanced attack path frameworks, establish engineering best practices for offensive tooling, mentor junior researchers, and serve as a technical authority on adversarial techniques and red team operations.

About the Company 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 cyber and electromagnetic domains, where the speed and complexity of operations exceeds human cognition. Our team doesn't just solve problems – we deliver game-changing outcomes that directly improve national security. We're pragmatic optimists who understand that while our mission of defending America and its allies is challenging, we can succeed.
