Review and approve critical frontend technical designs across teams, providing guidance on trade-offs, scalability, performance, accessibility, security, and vulnerability mitigation.
Remain hands-on by contributing to core shared components, architectural prototypes, performance improvements, and high-risk or security-sensitive areas.
Establish and enforce best practices for code quality, automated testing, dependency management, vulnerability remediation, and frontend operational excellence.
Own frontend standards for security testing, dependency scanning, secure authentication flows, and protection against common web vulnerabilities (e.g., XSS, CSRF).
Mentor and guide senior and staff engineers across teams, raising the organization-wide bar for frontend quality, security, and reliability.
Promote high standards for performance, resilience, usability, security, and delivery predictability.
Influence Agile execution, release planning, and cross-team dependencies in multi-product, multi-region environments.
