Smart Contract Engineer

Base is planning to bring a million developers and a billion users onchain. We need your help to make that happen.

We believe that the onchain platform is the most important builder platform since the internet ("online"). We believe that the onchain platform should be open source, free to use, and globally available. And we believe that in order to make it really work, we need all hands on deck, working together to scale in a secure, decentralized, easy-to-use way.

Base is incubated within Coinbase and plans to progressively decentralize in the years ahead. We believe that decentralization is critical to creating an open, global crypto economy that is accessible to everyone.

Base is built on Optimism's open-source OP Stack. We're joining as the second Core Dev team working on the OP Stack to ensure it's a public good available to everyone; and contributing a portion of sequencer revenue to funding public goods.

We are looking for a strong Smart Contract Engineer to join the Base team to help us continue scaling in order to pave the way for billions of people coming onchain.

• Architect and build secure smart contract protocols and backend services to connect Coinbase users with the crypto ecosystem
• Drive standardization in crypto protocols by designing and defining interfaces
• Work closely with the Base leadership and product team to set our onchain strategy and roadmaps
• Mentor and train other team members on smart contract engineering best practices

What we look for in you :

• 2+ year Experience with Solidity and smart contract development
• 3+ year Experience with backend/client side development
• Deep understanding of smart contract best practices and current industry patterns
• Extensive experience with crypto (Ethereum, DeFi etc.)
• Interest and passion for contributing to the crypto ecosystem
• Interest and passion for building secure, robust, scalable infrastructure

Nice to haves :

• Experience with Go
• Experience with zero-knowledge technology
• Contributions to open source crypto projects
• Crypto-forward experience, including familiarity with onchain activity such as interacting with Ethereum addresses, using ENS, and engaging with dApps or blockchain-based services.
