The Ethereum Foundation (EF) is a global non-profit organization dedicated to supporting Ethereum. Our mission is to help Ethereum remain secure, decentralized, and resilient over the long term by supporting critical protocol work and the broader ecosystem.
The Protocol Security team helps prevent vulnerabilities from reaching Ethereum mainnet.
We work across the execution layer, consensus layer, networking, specifications, testing, and client implementations to identify security issues before they become production incidents. Our work combines deep protocol knowledge with security research, manual review, fuzzing, AI-assisted analysis, audits, and coordinated disclosure.
We're looking for engineers who already understand Ethereum deeply.
The strongest candidates are already active in Ethereum protocol development. Ideally you have deep experience with the execution layer, consensus layer, specifications, testing infrastructure, or other protocol-critical components.
Examples include:
We're primarily looking for people with deep Ethereum protocol experience.
Ideal backgrounds include:
Security experience should include one or more of:
Languages commonly used include Go, Rust, Java, C#, Nim, and Python.
We're much less concerned with a specific number of years than with demonstrated technical depth.
