• Develop authentication capabilities end to end: passkeys/FIDO2, authenticator apps, security keys, verification, and biometric flows.
• Own the MFA orchestration layer with secure yet user-friendly balance between security and completion rate.
• Collaborate with AI teams to integrate facial recognition and AI capabilities into frontend and backend services.
• Maintain and evolve shared security components and SDKs used by multiple apps, focusing on performance and compatibility.
• Develop Node.js server-side logic: SSR, routing, session validation, localization, and performance optimizations.
• Build and refine BFF layer to aggregate services and translate errors into actionable frontend results.
• Implement platform-specific behaviors while keeping shared code clean and modular.
• Drive engineering quality through tests, instrumentation, and observable metrics.
• Use data to optimize login/verification funnels and reduce drop-offs.
• Collaborate across product, design, risk, support, backend, iOS, and Android teams to own end-to-end delivery.
