Full Stack Engineer (Frontend Oriented) — Identity & Security

About the Position

We are seeking a Full Stack Engineer (Frontend Oriented) - Identity & Security to join our team at Binance. This role is pivotal in ensuring the security and integrity of our user accounts, focusing on the development and maintenance of login, registration, and account security applications.

About the Team

The Identity & Security team is responsible for the front door to Binance. We manage the registration, login, and account security experience for over 300 million users. Our work involves building and operating social login, OAuth and third-party authorization, multi-factor authentication, passkeys and FIDO2, device management, account activity, and account closure. We are currently developing an in-house AI facial recognition security product for KYC verification and user safety.

Responsibilities

• Design, develop, and maintain login, registration, and account security applications across web and mobile clients.
• Build the in-house AI facial recognition security product end to end - KYC verification, liveness detection, face matching.
• Develop authentication capabilities end to end: passkeys / FIDO2 (WebAuthn), authenticator apps, security keys, SMS and email verification, and biometric flows.
• Own the multi-factor authentication orchestration layer - verification strategy, step-up logic, and user-level customization.
• Collaborate with the AI algorithm team to integrate facial recognition, liveness detection, and other AI model capabilities into the product frontend and backend.
• Maintain and evolve the shared security component and logic libraries consumed by multiple product applications.
• Develop and operate the Node.js server-side layer: server-side rendering, route-level authentication guards, session validation and redirects, localized routing, and first-paint performance.
• Build and refine the BFF layer - aggregating upstream security services and turning raw error codes into results the frontend can consume and users can act on.
• Implement platform-specific behavior for web, mini program, and low-end device targets.
• Drive engineering quality: unit and end-to-end test coverage, instrumentation and observability, build and local development experience.
• Use funnel and event data to find drop-off in login and verification flows, and drive optimization from evidence rather than intuition.
• Collaborate closely with product, design, risk, customer support, backend, iOS, and Android teams; independently own the end-to-end design and delivery of a sub-domain such as passkeys, MFA orchestration, or facial recognition verification.

Requirements

• Bachelor's or Master's degree in Computer Science, Engineering, or equivalent industry experience.
• 3–8 years of frontend or full stack engineering experience, including consumer-facing products taken from zero to one or evolved over multiple years.
• Strong web fundamentals: HTML, CSS, JavaScript/TypeScript, browser rendering, networking, caching, and performance optimization.
• Deep proficiency in React 18+ and TypeScript, with solid command of state management, data-fetching patterns, and complex multi-step form and flow orchestration.
• Production Node.js experience: server-side rendering or isomorphic applications, BFF layering, API aggregation and caching, and the ability to independently debug server-side runtime issues.
• A clear methodology for modeling complex flows.
• Solid engineering practice: modular architecture, component design, unit and E2E testing, CI/CD, and responsible judgment on breaking changes to shared libraries.
• Proficient with AI-assisted development tools with practical experience incorporating them into daily development workflows.
• Strong analytical and troubleshooting skills for diagnosing production issues, compatibility problems, and performance bottlenecks independently.
• Fluent in Mandarin, able to collaborate effectively with China-based teams.
• Effective communication in English within a distributed, cross-timezone, multi-team environment.

Nice to Have

• Experience at AI / computer vision companies in business-side frontend or fullstack development.
• Hands-on experience in identity and authentication: WebAuthn / FIDO2 / passkeys, TOTP, OAuth 2.0 / OIDC, JWT and token lifecycle management, risk engines, or device fingerprinting.
• Experience building to-C security products, identity verification, or KYC-related products.
• Experience replacing third-party vendor solutions with in-house systems, ensuring smooth business transition.
• Knowledge of AI model engineering: model inference services, RAG systems, AI Agent architecture, or computer vision model integration.
• Cross-platform experience: mini programs, hybrid applications, and in-app webview bridging and debugging.
• Experience shipping shared component libraries or SDKs to third-party consumers.
• Internationalization and localization at scale: date and number formatting, RTL, and regional compliance differences.
• Background in finance, payments, or another high-security domain, with an understanding of the product trade-offs compliance imposes.
• Experience with monitoring and alerting, staged rollout, and A/B experimentation.
• Docker / Kubernetes / CI-CD pipeline experience.

We Offer

• Shape the future with the world’s leading blockchain ecosystem.
• Collaborate with world-class talent in a user-centric global organization with a flat structure.
• Tackle unique, fast-paced projects with autonomy in an innovative environment.
• Thrive in a results-driven workplace with opportunities for career growth and continuous learning.
• Competitive salary and company benefits.
• Work-from-home arrangement (the arrangement may vary depending on the work nature of the business team).
