Validator Privacy Researcher
The Ethereum Foundation's Privacy & Scaling Explorations Team is seeking a Validator Privacy Researcher with a strong background in complex, multi-system problems and networking, as well as an interest in privacy and Ethereum.

About the Privacy & Scaling Explorations Team
We are a research group exploring practical applications for Zero-Knowledge Proofs and Scaling solutions. Our mission is to build the cryptographic primitives that will form the bedrock of a rich and vibrant ecosystem of decentralized applications (dapps), built on Ethereum. We do this through pure research projects, by building proofs of concept, and by facilitating the integration of technological primitives into decentralized applications.


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.
