About the Ethereum Foundation The Ethereum Foundation (EF) is a global non‑profit organization dedicated to supporting Ethereum and related technologies. Our mission is to do what is best for Ethereum’s long‑term success. Our role is to allocate resources to critical projects, to be a valued voice within the Ethereum ecosystem, and to advocate for Ethereum to the outside world.

About the Role Geth (go-ethereum) is an Ethereum execution client written in Go. It underpins the Ethereum protocol and many other projects around it. The team is seeking an individual contributor who likes working on a large and well‑established production codebase. We value individuals who are able to think on their own, see complex projects from start to finish without intervention, and are able to jump into whatever is necessary in the project.

Note for U.S. applicants, this means you have to be an early riser to apply successfully. The Geth team is decentralized with members in the USA, across Europe, and in China. As such, fully remote work is possible. We have a slight preference toward hiring in Boulder (Colorado) or Berlin (Germany) since Ethereum Foundation has offices there. The team has a daily call, and participation in calls and chat during European office hours is mandatory (9am UTC - 4pm UTC).

• Implement Ethereum execution layer protocol features
• Contribute to the Ethereum protocol roadmap
• Optimize reliability and efficiency of Geth

• An understanding of the Ethereum protocol and its architecture
• Previous contributions to large production Go codebases
• Availability during European day time

• Previous experience with go‑ethereum or a fork of it
• Database knowledge, particularly with leveldb / pebbledb
