Job summary

Binance is seeking a frontend/full-stack engineer in Australia to own the in-house AI facial recognition security product for KYC verification and attacker-resistant authentication flows. You will build end-to-end authentication, passkeys, MFA orchestration, and biometric verification while collaborating with AI, backend, and product teams.

You should have 3–8 years of experience with React/JS/TS, Node.js SSR, and strong web fundamentals.

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
• Strong web fundamentals: HTML, CSS, React, JavaScript/TypeScript, browser rendering, networking, caching, and performance optimization
• Production Node.js experience: server-side rendering or isomorphic applications, BFF layering, API aggregation and caching
• Clear methodology for modeling complex flows — authentication and verification are highly branched, stateful, interruptible, and resumable
• Solid engineering practice: modular architecture, component design, unit and E2E testing, CI/CD, versioning

Responsibilities

• Build the in-house AI facial recognition security product end to end — KYC verification, liveness detection, face matching
• 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
• Collaborate with AI algorithm team to integrate facial recognition, liveness detection, and other AI model capabilities
• Maintain and evolve the shared security component and logic libraries; manage bundle size and backward compatibility
• Develop and operate the Node.js server-side layer: SSR, routing guards, session validation, localization
• Build and refine the BFF layer — aggregate upstream security services and translate error codes
• Use funnel and event data to optimize login and verification flows
• Collaborate with product, design, risk, support, backend, iOS and Android teams; own end-to-end design for a sub-domain
