Responsibilities

As Senior Director of Engineering for Proactive Offense, you’ll set the engineering direction and build the organization that turns offensive security research and capabilities into dependable, customer-facing NodeZero products. You’ll lead through engineering managers, technical leaders, and senior individual contributors across multiple teams, balancing technical judgment with organization-wide strategy and execution.

You’ll partner closely with Product and leaders across Engineering, including Precision Defense and Platform, to align the Proactive Offense portfolio with customer needs and company priorities.
This is a highly visible leadership role central to Horizon3’s mission of delivering continuous, autonomous security testing at scale.
