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. It should be open source, free to use, and globally accessible. To achieve this, we need all hands on deck to scale in a secure, decentralized, and user-friendly manner.

What we look for in you:

• At least 5 years of software engineering experience, with 4+ years in web app development using JavaScript and frameworks like React and NextJS.
• Experience shipping user-facing features with onchain components.
• Knowledge of frontend architecture, security, performance, and usability best practices.
• Experience working with product and design teams, understanding lifecycle processes.
• Ability to write high-quality, well-tested, maintainable code.
