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 Ethereums 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
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.
P2P Networking team description
The P2P Networking team addresses a proven bottleneck in Ethereum today: the networking layer. We work on two fronts: we are improving the current stack to deliver on Ethereums short and medium-term ambitions while conducting radical first-principles thinking to redesign the networking layer from scratch for long-term scalability and growth. We collaborate closely with client implementers researchers and libp2p maintainers across the ecosystem.
We focus heavily on propagation: making incremental improvements to gossipsub and libp2p for immediate gains while exploring entirely new techniques like erasure coded broadcast for future breakthroughs. Our efforts also cover transport improvements large-scale simulation and benchmarking and deep instrumentation metrics and telemetry to profile the underlying network dynamics in order to make optimal decisions.
This dual approach helps us enable key endeavours like expanding blob capacity improving transaction throughput reducing slot times and enabling future architectures while strengthening security censorship resistance and privacy to maintain Ethereums core principles of decentralization and openness.
Internship projects may involve: broadcast techniques performance engineering network anonymity censorship resistance telemetry and simulation and/or transport optimizations.
Important dates:
This application closes on Dec 1st 2025. Applicants will receive decisions by January 30th 2026.
Note on AI-assisted review:
The hiring team will use an AI-assisted tool to help us review resumes for this role. Heres what that means:
- Your resume is anonymized before the AI review.
- We have been assured that your information will not be used to train AI models.
- Human reviewers make all final decisions. The AI tool does not reject or advance candidates automatically.
- The tool simply helps the hiring team manage a large volume of applications by highlighting potential fits.
We may use artificial intelligence (AI) tools to support parts of the hiring process such as reviewing applications analyzing resumes or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
