Job Description

The Web3 Foundation nurtures and stewards technologies and applications for the decentralized web. We collaborate with cutting-edge developer teams, researchers and community leaders to strengthen and extend the uses of decentralized technologies; building the future of identity, privacy, financial markets, commerce, and more.

Our core project at the moment is Polkadot, a protocol designed to connect blockchains and allow them to interoperate, share security and more. In addition, we are supporting the development of a number of technologies that form the Web 3.0 tech stack - such as decentralized messaging, distributed storage or secret management.

To encourage the adoption of our technologies and make those protocol accessible to other developers to re-implement and incorporate in their applications, as well as to increase transparency and auditability of the designed technologies and protocols, it is essential to maintain up-to-date specification of our technology stack.
