Direct Adversarial Cybersecurity Emulation (ACE) and Red Team engagements, coordinating stakeholders, managing risk, and delivering actionable security recommendations.
Provide technical leadership across multiple concurrent initiatives, ensuring quality, accuracy, and successful delivery while remaining hands-on with testing activities.
Define testing strategies, review findings and risk assessments, and guide remediation efforts to reduce organizational risk.
Partner with incident response, engineering, product, and business teams to identify vulnerabilities, evaluate attack paths, and strengthen security controls.
Drive innovation through automation, tooling, process improvements, AI/ML-enabled security capabilities, and the expansion of Red Team services.
Communicate technical risks and business impacts to executive and technical audiences, promote knowledge sharing, and foster a strong security-focused culture.
