What you'll do
- •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
Conditions
- •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)
