Front End Web3 Developer Job Description Template

The front end web3 developer owns the interface between people and the protocol. The job is harder than conventional front end work because every action costs money, cannot be undone and may fail for reasons the user does not understand.

• Implement wallet connection and account state management
• Design clear transaction confirmation and status flows
• Communicate gas costs, slippage and approval scope plainly
• Handle pending, failed and replaced transactions gracefully
• Display on chain data accurately with appropriate loading and error states
• Ensure interfaces work across wallets and networks
• Optimize front end performance against slow RPC responses
• Implement accessibility standards across the application
• Work with design and contract engineers on interaction patterns

Education

• Bachelor’s degree in computer science or equivalent practical experience
