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.

EF Internship

As part of our mission to advance blockchain systems, interns will contribute to bleeding edge research that spans computer science, distributed systems, crypto-economics, and mechanism design. This program offers a unique opportunity to work closely with Ethereum Foundation researchers, their collaborators, and other contributors across the ecosystem, tackling both foundational and applied research challenges. Interns will also have opportunities to share their findings through ethresear.ch, academic publications, or conference submissions helping shape the future of Ethereum.

Interns can choose to work remotely but are encouraged to work out of an EF office (likely Berlin, Germany). In addition, interns will be invited for an in-person cohort meetup in the summer.

The duration of the internship is 12 weeks during summer 2026.

Protocol Security team description

The Protocol Security Research team safeguards Ethereum’s integrity. Through coordination, meticulous code reviews, developing advanced tooling, and real-world simulations, we focus on securing the network and its critical components. Our hands-on approach includes managing the bug bounty program, continuously monitoring the network, and collaborating with client teams. We’re committed to identifying and mitigating risks to Ethereum mainnet.
