  • Shared dependencies and versioning
• Build robust integration patterns with backend services (GraphQL/REST/BFF)
• Ensure platform scalability across teams and products
• Security & Compliance
• Enforce frontend security best practices:
  • CSP, XSS prevention
  • Secure auth flows (OAuth, OIDC)
• Work with platform/security teams on compliance requirements
• Leadership & Influence
• Act as a multiplier across teams, not just an individual contributor
• Influence product and business decisions via technical insight
• Represent frontend engineering in executive-level discussions
• Drive engineering culture and innovation
