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.

How do I start a Web3 career?
If you're interested in starting a career in Web3, here are a few steps you can take:
- First, it's important to gain a solid understanding of the underlying technologies that make up the Web3 ecosystem, such as blockchain, cryptography, and decentralized networks. You can do this by reading books and articles, taking online courses, or attending workshops and conferences.
- Next, you'll want to build a portfolio of projects that showcase your skills and knowledge. This can include creating dApps (decentralized applications) using blockchain platforms such as Ethereum, contributing to open-source projects, or writing articles and tutorials on Web3-related topics.
- Networking is also an important part of any career, and the Web3 space is no exception. Attend meetups and conferences, join online communities, and make connections with other professionals in the field. This can help you learn from others, share your own expertise, and potentially find job opportunities.
- Finally, consider getting certified in Web3 technologies. There are several organizations that offer certification programs, which can help demonstrate your proficiency and set you apart from other candidates in the job market.
