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
[Donât worry if you donât meet all of these criteria, weâd still love to hear from you anyway if you think youâd be a great fit for this role. Just explain to us why in your cover letter].
