The Ethereum Foundation (EF) is a global non‑profit organization dedicated to supporting Ethereum. Our mission is to ensure the long‑term success of Ethereum by allocating resources to critical projects, being a positive voice within the Ethereum ecosystem, and advocating for Ethereum to the outside world.

We’re seeking passionate and collaborative individuals who are excited about testing Ethereum to help reduce the risk of software failures across the protocol. As part of the EF Testing Team, you'll collaborate with other testers, dev operatooors, client developers, and protocol researchers to ensure protocol upgrades are thoroughly and efficiently tested.

As a Protocol Tester, you’ll use your technical expertise to enhance testing methods, implement tests for new and existing protocol features, and improve our test infrastructure. This role involves working with complex subsystems that are integral to the Ethereum Protocol.
