Job Description
This position is seeking a Senior Wallet Development Engineer to lead the development of browser plugin wallets and decentralized application (Dapp) web pages. The ideal candidate will be responsible for designing and implementing secure, user-friendly wallet interfaces while ensuring seamless integration with blockchain protocols. Key tasks include translating product designs into functional front-end solutions, collaborating with cross-functional teams to deliver high-quality digital products, and maintaining technical documentation for wallet development processes. The role also involves optimizing wallet performance, enhancing user experience through intuitive design, and ensuring compliance with security standards across all platforms. This role requires a deep understanding of both front-end and back-end development to create end-to-end solutions for wallet systems. The candidate should be able to work in a fast-paced environment, adapt to changing requirements, and contribute to the long-term vision of decentralized finance (DeFi) and blockchain applications. Strong analytical and debugging skills are essential to identify and fix issues in complex systems. The ability to stay current with industry trends and emerging technologies will help drive innovation and improve the overall wallet development process.
Key Responsibilities
- Develop and optimize browser plugin wallets with a focus on security, performance, and user experience, including features like key management, transaction signing, and network connectivity.
- Create responsive and accessible Dapp web pages that align with product specifications and meet modern web standards (e.g., HTML5, CSS3, and accessibility guidelines).
- Implement front-end components using JavaScript/TypeScript, ensuring compatibility with both desktop and mobile browsers through progressive enhancement techniques.
- Collaborate with backend engineers to integrate wallet functionality with blockchain APIs, smart contracts, and decentralized infrastructure.
- Design and maintain scalable, modular codebases that support continuous integration and deployment pipelines for wallet development.
- Conduct code reviews, debug complex issues, and ensure the technical implementation adheres to best practices and security protocols.
- Stay updated on emerging web technologies, blockchain standards, and wallet development trends to drive innovation in product solutions.
- Document technical processes, APIs, and system architecture for wallet development to facilitate team collaboration and knowledge sharing.
- Perform user testing and gather feedback to refine wallet features and improve usability across different user scenarios.
- Ensure cross-browser compatibility and mobile responsiveness for all wallet-related applications and interfaces.
Job Requirements
- Proven experience (5+ years) in full-stack web development with a strong focus on front-end technologies, including JavaScript, TypeScript, and modern frameworks like React.
- Advanced proficiency in JavaScript/TypeScript, with hands-on experience in tooling ecosystems (e.g., Webpack, Babel, ESLint) and functional libraries (e.g., Redux, Axios, React Router).
- Strong understanding of Node.js development, including server-side logic, API design, and integration with blockchain platforms (e.g., Ethereum, Solana).
- Ability to produce high-quality, responsive web designs that adapt to various screen sizes and device capabilities while maintaining performance benchmarks.
- Excellent English communication skills, with the capacity to interpret and implement technical documentation, specifications, and research materials.
- Collaborative mindset with experience in agile development environments, including Scrum or Kanban methodologies for project management.
- Knowledge of blockchain fundamentals (e.g., cryptographic principles, consensus mechanisms) to ensure technical feasibility of wallet features.
- Experience with version control systems (e.g., Git) and CI/CD pipelines for automated testing and deployment of wallet applications.
- Strong problem-solving skills and attention to detail to ensure the reliability and security of wallet systems under high-traffic scenarios.
- Ability to work independently and as part of a team to deliver complex wallet development projects on time and within scope.
- Proficiency in UI/UX design principles to create intuitive and accessible interfaces for wallet users.
- Experience with cryptographic libraries and protocols to implement secure wallet functionalities.
- Understanding of decentralized systems and blockchain architecture to ensure seamless integration with distributed networks.
- Ability to analyze and resolve technical challenges related to wallet security, performance, and scalability.
- Excellent teamwork and communication skills to collaborate effectively with designers, product managers, and other engineers.
