Lead security architecture reviews for new and existing applications, evaluating designs against frameworks such as OWASP, NIST, and SANS.
Integrate zero-trust principles and defense-in-depth strategies into application architecture to reduce attack surface and support enterprise risk management goals.
DevSecOps & Secure Development Lifecycle
Define and maintain a standardized set of enterprise application security requirements and produce metrics to report performance against those requirements.
Lead threat modeling sessions for new application features and system integrations, producing actionable remediation guidance for development teams.
Champion secure coding standards and developer security enablement programs in collaboration with platform and application engineering teams.
Risk, Compliance & Stakeholder Engagement
Analyze complex security requirements across multiple technology domains and design comprehensive security solutions that address enterprise risk and regulatory compliance obligations.
Communicate security architecture designs, risk assessments, and remediation recommendations to technical and non-technical stakeholders across business units.
Coordinate security design reviews and approval processes, facilitating alignment between security, engineering, and enterprise architecture teams.
Contribute to JLL's application security strategy roadmap, identifying emerging threats and recommending enhancements to the secure development and architecture programs.
Mentorship & Team Leadership
Provide technical guidance and mentoring to junior security engineers, developers, and architects on application security principles, secure coding practices, and architectural standards.
Lead cross-functional security initiatives, driving collaborative approaches to security integration across development and architecture teams.
Support secure development training and awareness programs to build security competency across engineering organizations.
