Protocol Engineer (Native Libraries)

Waku is part of the Logos tech stack, a movement supporting the development of the decentralised web. Logos technologies lay the foundations for a freer internet upon which communities can evolve into network states. Each protocol in the Logos stack seeks to empower its users while upholding civil liberties and fundamental freedoms.

As a p2p messaging protocol, born from the original Web3 vision, Waku is a decentralised, censorship-resistant, privacy-preserving communication network that enables anyone to message, interact, collaborate, and coordinate without worrying about surveillance or deplatforming.

We are a cypherpunk group, looking for other builders to join a principle-first organisation and build truly decentralised software.
