The role

Summary

Join Airwallex's Frontend Onboarding team as a Software Engineer to architect and deliver scalable React-based web applications that power account setup and customer activation for a global fintech platform serving over 250,000 businesses. You'll build micro-frontend applications with TypeScript, GraphQL backends, and cloud-native infrastructure while maintaining compliance and security standards critical to financial operations. This role requires 3+ years of frontend development experience with deep expertise in React, TypeScript, and financial systems architecture.

What you'll do

React and TypeScript Development: Engineer high-performance frontend applications using modern React and TypeScript to build responsive user interfaces for the onboarding platform. Write clean, maintainable code that adheres to SOLID principles and industry best practices.

Micro-Frontend Architecture: Design and implement domain-based micro-frontend web applications using single-spa framework, enabling independent deployment and scalability across the onboarding ecosystem. Ensure seamless integration between micro-frontend modules while maintaining architectural coherence.

GraphQL and Backend Integration: Leverage Apollo GraphQL to build scalable Backend-for-Frontend (BFF) services using Node.js, establishing contract-based integration patterns with backend systems. Optimize data fetching and caching strategies to enhance application performance.

Design System and Component Development: Collaborate with design and product teams to architect and maintain a comprehensive design system. Build reusable UI components benchmarked against Material-UI and Ant Design, delivering consistent user experiences across all onboarding workflows and regulatory screens.

NPM Package and Library Development: Create and publish production-grade NPM packages and JavaScript SDKs that customers can easily integrate into their applications. Maintain documentation, versioning, and backward compatibility for distributed widget libraries supporting the Airwallex ecosystem.

Cloud Infrastructure and DevOps: Deploy micro-frontend applications and Node.js services on GCP and Aliyun Kubernetes environments using GitLab CI/CD pipelines. Implement infrastructure-as-code practices, container orchestration, and CDN configurations leveraging Cloudflare for optimal global performance.

Quality Assurance and Testing: Establish and maintain comprehensive testing strategies using React Testing Library, Jest, and Cypress for unit and end-to-end testing. Achieve and maintain 80%+ code coverage while designing robust test suites that validate critical onboarding workflows and compliance requirements.

Headless CMS and Static Site Generation: Implement serverless CMS systems using Contentful and Next.js to power corporate websites, branding landing pages, and marketing content. Build scalable content delivery architectures that support multi-regional deployment and dynamic content management.

Security and Compliance Implementation: Develop with security-first principles to protect sensitive customer data and financial transactions. Implement authentication, authorization, and data encryption best practices throughout the application. Ensure compliance with KYC, AML, and financial regulatory requirements.

Product Collaboration and Requirements Validation: Partner with Product Management, Design, and Operations teams to translate business requirements into technical solutions. Validate product hypotheses through data-driven feedback mechanisms and iteratively enhance features based on user behavior analytics.
