Frontend Engineer at TanTin Technology

The Frontend Engineer position at TanTin Technology requires specialized expertise in blockchain wallet development with a strong focus on security and performance optimization. Candidates must demonstrate both technical proficiency in modern frontend frameworks and deep understanding of blockchain protocols.

• Minimum 3 years experience with React/Vue and Web3.js/Ethers.js libraries
• Expertise in blockchain interaction standards (JSON-RPC, WalletConnect) and security practices
• Practical knowledge of transaction lifecycles, Gas calculation, and cross-chain mechanisms
• Proven ability to implement wallet core functions like transaction signing and DApp connectivity
• Open-source contributions to wallet projects (Keplr/Rabby) are highly valued

TanTin Technology appears to be a blockchain-focused company developing public chain solutions. Their emphasis on public chain wallet development suggests they are building infrastructure-level products rather than consumer applications. The detailed requirements around EIP-6963 and Account Abstraction indicate they're working on cutting-edge wallet technologies that may integrate with multiple chains. Their fully remote policy and mention of 'distributed team environment' suggest a globally distributed Web3 company structure.

As an interviewer for TanTin, I would prioritize candidates who can demonstrate both technical depth in frontend security implementations and practical blockchain experience beyond simple DApp integration. The ideal candidate should showcase contributions to wallet-related open-source projects and articulate sophisticated understanding of private key management architectures. Cultural fit assessment would focus on self-motivation in remote settings and ability to stay current with rapidly evolving blockchain standards.
