We are seeking a skilled Frontend Developer to join our team. The ideal candidate will be responsible for developing and optimizing web management backends, H5 payment pages, and React Native wallet applications. This role involves deep integration with payment gateways and EVM/Solana nodes to implement core blockchain interactions such as wallet connections, transaction signing, and real-time status tracking.

- Led or deeply participated in payment/financial modules (e.g., online deposits, withdrawals, order centers, real-time wallet balance displays, card binding).
- Implemented blockchain DApp features (wallet connections, transaction signing, real-time tracking, token/NFT displays) using ethers.js, web3.js, wagmi, or viem.
- Developed high-interaction trading dashboards with virtual scrolling tables, WebSocket charts, multi-step payment flows, and form validation.
- Built and published React Native digital wallet/payment apps (mnemonic/private key management, QR payments, transaction history).
- Worked on large-scale TypeScript + React 18 + Hooks projects with state management (Redux Toolkit/Zustand/Recoil) and UI frameworks (Tailwind/MUI/AntD).

Understand Employer Recruitment Intent

As a cultural media company venturing into blockchain payments, 八部半文化传媒 likely seeks to expand its digital payment solutions while maintaining creative interfaces. The emphasis on React Native wallet apps and H5 payment pages suggests they're building consumer-facing fintech products alongside their media offerings. Their requirements reveal three strategic needs: 1) Bridging media content with blockchain monetization, 2) Creating secure self-custody payment tools for Chinese users, 3) Developing internal admin systems for hybrid media-finance operations.

MyJob Interviewer Says

We'll prioritize candidates who demonstrate actual blockchain implementation experience over theoretical knowledge. Be prepared to walk through your security approach for payment components and discuss specific optimization techniques you've applied in React Native projects. Cultural fit matters too - we need engineers who understand both financial rigor and creative media environments.

AI Matching Suggestions

Tailor your application to highlight blockchain payment implementations and React Native optimizations:

Showcase 2-3 payment/blockchain projects prominently, detailing your role in security implementations
Quantify performance improvements (e.g. 'Reduced React Native bundle size by 30%')
Prepare concrete examples of handling WebSocket data flows and virtualized tables
Demonstrate knowledge of Chinese payment regulations if applicable
Highlight any media/fintech crossover experience
