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.
STEEL team description
The Specifications and Testing for the Ethereum Execution Layer (STEEL) team consists mainly of two projects: Ethereum Execution Layer Specification (EELS) and Ethereum Execution Specification Tests (EEST).
The EELS project is responsible for the main Ethereum protocol reference specification written in Python, which aims towards replacing the yellow-paper specification and being a crucial aid to the EIP process in order to provide a prototyping framework for new updates.
The EEST project is responsible for the Ethereum protocol reference tests, used by all clients to detect consensus issues during new hard-fork implementations and regressions.
The team also supports testing efforts for the consensus-specs, takes care of maintaining and improving the tooling, frameworks, documentation and guidance required to facilitate the client developers with the consumption of the tests, which includes the EEST, the legacy ethereum/tests repository, and also integration tests in the form of various hive simulators.
