Binance offerings range from trading and finance to education research payments institutional services Web3 features and more. We leverage the power of digital assets and blockchain to build an inclusive financial ecosystem to advance the freedom of money and improve financial access for people around the world. About the Team The Identity & Security team owns the front door to Binance. We build and operate the registration login and account security experience used by every one of our 300M+ users — social login OAuth and third-party authorization multi-factor authentication passkeys and FIDO2 device management account activity and account closure. We are currently building an in-house AI facial recognition security product for KYC verification and user safety replacing our existing third-party vendor solution. This is a to-C product serving hundreds of millions of users directly impacting account security and identity verification experience at scale. Our work sits where three forces meet enormous scale strict security and regulatory constraints and the reality that one extra verification step can block an attacker or lock out a legitimate user. We ship across web mobile mini programs and in-app webviews and we publish the shared authentication libraries and SDKs that the rest of Binance builds on. ### Responsibilities Design develop and maintain the 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 — replacing the existing third-party vendor solution Build 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 — balancing security strength against completion rate with measurable outcomes Collaborate closely with the AI algorithm team to integrate facial recognition liveness detection and other AI model capabilities into the product frontend and backend building high-concurrency low-latency online inference services Maintain and evolve the shared security component and logic libraries consumed by multiple product applications and the authentication SDKs published to teams across the company take responsibility for bundle size initialization behavior and backward compatibility 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 while keeping shared and platform-specific code cleanly separated 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 ### Minimum qualifications 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 — authentication and verification are highly branched stateful interruptible and resumable and need to be abstracted into testable reusable models rather than nested conditionals Solid engineering practice modular architecture component design unit and E2E testing CI/CD and responsible judgment on breaking changes to shared libraries (versioning staged rollout rollback) Proficient with AI-assisted development tools (Cursor / Claude Code / Copilot etc.) 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 — multi-entry bundling tree-shaking semantic versioning and integration support 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 Why Binance Shape the future with the world’s leading blockchain ecosystem Collaborate with world-class talent in a
