About the Role 

We’re looking for a Director of Application Security to architect and lead an AI-native, agent-driven Application Security function at Zeta.  

This is a hands-on, player/coach leadership role focused on shifting security decisively left—embedding security intelligence directly into the software development lifecycle, CI/CD pipelines, and AI-powered development workflows. 

Rather than operating as a traditional gate or review function, Application Security at Zeta is evolving into a continuous, autonomous capability: powered by policy-as-code, security agents, real-time risk signals, and deep integration with how engineers build software. 

Zeta is at the forefront of the AI-native transformation of marketing, having launched Athena by Zeta—a superintelligent, conversational AI agent deeply embedded in the Zeta Marketing Platform. As Zeta accelerates into this AI-driven, agentic future, security is foundational—not optional. 

KEY RESPONSIBILITIES 

Leadership & Strategy (AI-Native Player/Coach) 

- Define and drive an AI-native Application Security vision and roadmap. 

- Design the operating model for agentic AppSec, including security copilots and policy-enforcing agents. 

- Act as a hands-on technical leader shaping secure architectures. 

- Build and mentor a modern Application Security team focused on leverage and automation. 

 

Agentic Threat Modeling & Continuous Validation 

- Evolve threat modeling into continuous, system-aware analysis.
