• Technical Performance: Architect integrations with enterprise DLP/CASB platforms, SIEM, and identity/access workflows; support early, automated detection of vulnerabilities in code, containers, and infrastructure-as-code templates, including flaws introduced by AI components or data pipelines feeding AI models.
• Mentorship & Quality: Provide technical guidance and review for mid-level engineers and contribute to deliverables including the Enterprise Architecture and Deployment Plan, Discovery and Classification Configuration, and AI Governance and Enforcement Configuration.
• Continued Proficiency: Stays current with emerging AI technologies and cybersecurity trends to ensure best-in-class practices.
