We’re seeking a Lead Application Security Engineer to help advance Zeta Global’s application and platform security posture through AI-native security practices, intelligent automation, and scalable security engineering. You’ll play a critical role in embedding security throughout the software development lifecycle by using AI-driven tools, automated controls, and data-informed risk prioritization to ensure our systems, applications, and AI-powered platforms are built securely from the ground up.

Zeta operates at massive scale, powering billions of consumer profiles and petabytes of data across real-time, AI-powered marketing platforms. In this role, you’ll collaborate with Engineering, Product, QA, Dev Ops, and AI platform teams to identify risks, design secure-by-default patterns, and build automated security capabilities that enable secure innovation at speed.

This position offers significant technical scope, cross‑functional visibility, and the opportunity to directly influence the company’s security maturity through AI-enabled threat modeling, automated validation, intelligent vulnerability management, and proactive defense.

• Use AI-assisted threat modeling capabilities to identify application, platform, API, cloud, data, and AI/ML security risks early in the design and development process.
• Leverage automated security review tools to evaluate architecture, design documents, code changes, APIs, and data flows for security gaps and control weaknesses.
• Drive AI-assisted code security reviews using SAST, DAST, SCA, secrets detection, IaC scanning, container scanning, and contextual risk analysis.
• Use automation and intelligent correlation to assess third-party libraries, APIs, vendor integrations, and open-source dependencies for security, compliance, and supply‑chain risk.
• Support AI-enabled red team, blue team, and incident response simulations to validate detection, prevention, and response capabilities.

• Partner with developers and QA engineers to embed AI-driven security testing and automated risk detection into CI/CD pipelines.
• Build and improve security automation that provides real‑time feedback to developers during design, coding, testing, release, and deployment.
• Use AI-assisted analysis to review architecture and design artifacts, identify risks earlier, and recommend secure implementation patterns.
• Contribute to intelligent security checkpoints that reduce manual review effort while improving consistency, traceability, and developer velocity.
• Help design scalable guardrails, reusable security controls, and policy-as-code capabilities across application and platform teams.

• Monitor evolving application, cloud, API, AI/ML, and data security risks using AI-assisted threat intelligence, vulnerability intelligence, and attack-pattern analysis.
• Identify and evaluate AI-specific threats such as prompt injection, data poisoning, model abuse, model leakage, insecure tool use, and sensitive data exposure.
• Assist in designing and deploying proactive defense mechanisms across applications, APIs, data platforms, and AI-powered systems.
• Use automated signals, telemetry, and risk scoring to support…
