• Build and maintain security reference architectures and standardized secure design patterns for product teams
• Lead threat modeling, security design and code reviews for new features, services, and major architectural changes
• Design and build AI-assisted workflows that automate and accelerate product security areas
• Evaluate AI risks across internal and external applications
• Collaborate with Product, Engineering, Data, Compliance, Legal, and other teams to identify and drive mitigation for product and data security risks

• Demonstrated ability to build and maintain security reference architectures.
• Strong experience leading threat modeling and security design reviews including security-focused code reviews.
• Applied knowledge with industry security and compliance frameworks (OWASP, NIST, CIS, SOC 2/ISO 27001 concepts).
• Highly hands-on engineer with proven ability to operate autonomously, drive multiple complex cross-functional efforts, and influence independently.
• Excellent communication and collaboration skills, including the ability to explain complex security concepts to both technical and non-technical stakeholders.
