## About the role

As Senior Director of Engineering for Precision Defense, you'll set engineering direction and build the organization that turns NodeZero's offensive capabilities into proactive, actionable defense. You will lead across three connected pillars: Tripwires and Deception, Security Controls Validation, and Blue Team Agents. Together, these teams help customers design their defenses, test whether they work, and detect attacker activity that makes it past the perimeter.
