As a Senior Frontend Engineer, you will closely collaborate with product, design, and backend engineers to lead and implement the frontend development of the Mantle Bank payment product.
Your responsibilities will include building and maintaining frontend products for payment, such as user wallets, payment pages, payment status pages, and transaction history.
You will be responsible for the on-chain payment interaction interface (e.g., wallet interactions, transaction confirmations) and the off-chain payment experience (e.g., card payments, KYC processes).
You will enhance overall frontend performance and user experience by optimizing response speed and cross-platform compatibility.
You will continuously monitor Web3 user habits to drive product iteration and optimization.
You will interface with backend/blockchain engineers regarding payment-related API/contract interfaces to ensure accurate data synchronization and status updates.

You must have solid frontend development skills and be proficient in modern frameworks such as React, Vue, Next.js, and Typescript.
You should be skilled in HTML5, CSS3, JavaScript, and component-based development.
Familiarity with RESTful APIs, WebSocket, and frontend-backend collaboration mechanisms is required.
You should have practical experience in frontend performance optimization and state management (e.g., Redux/Zustand).
Experience in developing payment-related products (e.g., wallets, bank cards, cryptocurrency trading platforms) is a plus.
Familiarity with the Web3 technology stack (e.g., EVM, MetaMask, wallet connection protocols, on-chain transaction processes) is advantageous.
You should possess good product thinking and be sensitive to user experience.
Familiarity with testing frameworks and continuous integration processes (e.g., Jest, Playwright, GitHub Actions) is beneficial.
Experience in fintech, cryptocurrency, or DeFi projects is preferred.

Mantle offers a dynamic and innovative work environment focused on the future of financial technology.
You will have the opportunity to work on cutting-edge projects within the rapidly evolving Web3 space.
The company values diverse experiences and encourages applications from individuals who may not meet all criteria but have valuable skills to contribute.
You will be part of a community of builders and innovators, contributing to a significant capital pool of $200M aimed at supporting the next generation of developers.
The role allows for remote work within the APAC region, providing flexibility in your work environment.
