About Waku

We are building Waku (Waku.org) as a public good infrastructure. Waku is the messaging layer of Web3.

It is a decentralized, censorship-resistant, privacy-preserving communication network that enables anyone to send and receive messages without worrying about surveillance or deplatforming.

We are developing 3 open source implementations of Waku:

• Nwaku. https://github.com/waku-org/nwaku: the reference implementation and service node
• Js-waku, https://github.com/waku-org/js-waku: for the browser
• Go-waku: https://github.com/waku-org/go-waku: to integrate as a library in native applications

We are enabling Ethereum builders to create new projects with a fully decentralized architecture, think dApp to Wallet notifications, NFT marketplaces, censorship-resistant chat, layer-2 decentralization and more.

Waku enables a variety of complex use cases and applications. To facilitate the adoption of Waku, you will design and implement application protocols to provide to dapp developers as off-the-shelf SDKs.

Key Responsibilities

• Implement, design and enhance secure and reliable chat protocols over Waku, a gossipsub-based decentralized communication network.
• Collaborate with researchers using protocol RFCs as a medium, implement protocol PoCs, then proceed with integration in the main library, and collaborate with QA for extensive testing.
• Liaise with internal consumers of the chat library, understand usage and requirements and UX impacts of design, support with any issue encountered.
• Liaise with Waku protocol engineers to report bugs, stay informed of new functionalities and provide feedback on Waku protocols and implementations.
• Enable the testing of the existing chat functionalities (present in a larger library), by building binaries that can be used for test automation and extract said functionalities in a separate library.

You ideally will have

• Have experience building applications with complex logic, cutting-edge technology or applied research.
• Experience with Golang or other system/backend languages such as C/C++/C#/Java/Rust, etc.
• Have experience building and designing instant messaging and chat protocols that include cryptography such as end-to-end encryption.
• Have a deep interest in blockchain and decentralized technologies and understand how they work.

Bonus points if

• You are already familiar with the Ethereum community
• You have experience working for an open source organization
• You have experience working async

[Don’t worry if you don’t meet all of these criteria, we’d still love to hear from you anyway if you think you’d be a great fit for this role. Just explain to us why in your cover letter].
