Director of Engineering, Webapp & AI Attack

Get to Know Us Horizon3 is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find and fix and verify exploitable attack vectors before criminals exploit them. Our flagship product, the NodeZeroTM platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises. It is used by ITOps/SecOps teams, consulting pentesters, and MSSPs and MSPs.  We are a fusion of former U.S. Special Operations cyber operators, startup engineers, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools, false positives resulting in alert fatigue, blind spots, "checkbox” security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants. Collectively, we are a team of learn it alls, committed to a culture of respect, collaboration, ownership, and results.   WHAT YOU’LL DO As Director of Engineering for Webapp and AI Attack, you’ll set direction and lead the teams that turn Webapp and AI related offensive security expertise into dependable, customer-facing NodeZero capabilities. You’ll own the strategy, execution, and organizational health of this portfolio, partnering with engineering managers, technical leaders, Product, Platform, and customer-facing teams. You’ll guide capabilities from discovery and research through productization and ongoing operation. That includes improving how NodeZero maps and tests modern web applications, and building responsible, repeatable ways to assess AI-enabled and agentic systems. This is a people and portfolio leadership role: you’ll maintain enough technical depth to shape decisions and raise the quality bar while enabling teams and technical leaders to own implementation. KEY RESPONSIBILITIES ORGANIZATION LEADERSHIP & STRATEGY - Lead and develop the Webapp and AI Attack engineering teams, setting clear ownership, goals, and expectations across the portfolio. - Define a coherent strategy and roadmap that connect customer needs, product priorities, offensive research, and durable engineering investments. - Build an effective leadership structure as the organization grows; hire, coach, and develop engineering managers, technical leaders, and senior individual contributors. - Set operating mechanisms that make outcomes, progress, capacity, quality, dependencies, and risks visible without adding unnecessary process. - Own the health and performance of the organization, including talent planning, career development, timely feedback, accountability, and succession planning. - Foster an inclusive, psychologically safe environment where teams can raise risks, learn from failures, and do their best work. WEBAPP ATTACK CAPABILITIES - Set direction for NodeZero’s web application attack portfolio, spanning application discovery, crawling and browser automation, authentication and session handling, attack coverage, and the feedback between discovery and testing. - Ensure the platform can reliably map pages, forms, APIs, parameters, and authentication surfaces across modern applications—including JavaScript-heavy single-page applications and complex user flows. - Partner with technical leaders to improve attack coverage, framework breadth, and the quality of the application context available to downstream testing. - Establish benchmarks, regression practices, and production signals that reveal coverage gaps and prevent quality from silently degrading as appl
