Want to work with highly motivated individuals on high-performance teams? Join WWT today! What will you be doing? The emphasis of this role is to be the dedicated technical lead for developing WWT’s defensive AI operations, specifically focused on utilizing massive open-source models to solve the vulnerability management problem at an enterprise scale.

This position requires an elite technical leader who is adept at advanced machine learning, can speak to complex exploit mechanics, and ensure our defensive posture rapidly evolves to keep pace with AI-accelerated offense and frontier-model-class intelligence.

This role will also involve guiding the organization away from manual triage by anticipating exploit chaining and integrating the largest open-source AI models to ensure our defensive strategies remain ahead of advanced adversaries.

Responsibilities Partner with the GS&A Cyber Practices to utilize to model and evaluate attack paths and how AI can help defenders operate at the speed of attackers.

Deliver measurable outcomes to customers and partners as to how AI and ML-based science improves cybersecurity defenses.

Participate in industry forums on the topic of using AI for defense and be able to perform technical demonstrations how AI is used for offensive operations.

Architect and deploy advanced machine learning models that analyze, score, and prioritize vulnerabilities at an unprecedented scale.

Continuously evaluate, integrate, and fine-tune frontier models to match and counter frontier-model-class attack methodologies and AI-driven exploit chaining.

Shift organizational operations entirely away from manual triage by providing automated, model-assisted workflows for immediate remediation guidance.

Ingest and model complex threat data, scanning code with open-source models to train systems on handling the exploding volume of automated vulnerability reports.

Dedicate 100% of operational bandwidth to defensive cybersecurity measures, using AI to neutralize emerging threats before they can be weaponized against our customers.

Act as the technical expert for data architecture, statistical modeling, and advanced machine learning applied to massive enterprise datasets.

Drive the vulnerability prioritization problem space autonomously from concept to customer-facing deployment without distraction.

Apply deep cybersecurity domain knowledge, specifically regarding vulnerability management, exploit mechanics, and patch gap mitigation, to all AI models.
