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.

Key responsibilities:

• Design, implement and document Waku nim libraries and node (nwaku)
• Collaborate and support the Research team with the implementation of new protocols
• Investigate and fix issues in nwaku and upstream libraries such as nim-libp2p
• Maintain an array of bindings and wrappers over the nim library to enable usage of Waku in other languages (Rust, NodeJS, Golang)
• Optimize nwaku and upstream libraries for usage on various environments (VPS, laptop, mobile, Raspberry Pi)
• Support dApp developers in using nwaku and other Waku libraries/bindings

You ideally will have: 

• At least 2 years of experience in low-level or statically typed languages (C, C++, Rust or Go)
• Experience building applications with complex logic, cutting edge technology or applied research, including for network environments
• Ability to learn new concepts and technologies quickly; you are a polyglot
• You have a deep interest for blockchain and decentralized technologies and understand how they work

Bonus points: 

• You are already familiar with the Ethereum community or you are in Web3 or blockchain development
• You have experience with any libp2p implementations
• You have experience with maintaining bindings, especially in a mobile or embedded context
• You have experience working for a remote only open source organization

Hiring process:

1. Intro call with PeopleOps (30 minutes)
2. Interview (technical) with nwaku team member (1h)
3. Pair programming session with a nwaku team member (1h)
4. Final interview with Waku Lead (45minutes to 1h)
