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:

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.

We are looking for a Software Engineer who is passionate about Ethereum, and decentralization. And who would relish the opportunity to champion Waku to other Web3 projects and developers.


The Role

This role will be part of Vac’s Secure Messaging (SeM) team. We research and design modular p2p protocols for scaling, secure, private, anonymous, and censorship-resistant communications. The main focus is Waku, the communication layer for Web3.


Key Responsibilities

  • Research and develop open P2P protocols for secure messaging.
  • Research efficient, scaling solutions for P2P communications.
  • Build incentivized, distributed systems.
  • Use a layered protocol approach that is mindful and explicit about what it requires, what it provides, under what threat models, and with what trade-offs.
  • Combine cryptoeconomics and traditional technologies to create a sustainable, scalable, distributed, and fault-tolerant system.
  • Use libp2p to build application-level protocols.
  • Interpret and implement solutions based on academic research.
  • Provide feedback on overall design decisions, and participate in code reviews.
  • Write Nim code.


You ideally will have

  • A passion for blockchain technology, privacy-preserving technology and decentralization.
  • A strong academic background.
  • Experience with encryption and key exchange mechanisms.
  • Experience with low level/strongly typed languages (C/C++/Go/Rust).
  • Experience building networking-heavy applications and p2p networking specifically.
  • Familiarity with message propagation in loosely connected networks.
  • Familiar with p2p building blocks such as gossiping, routing and discovery (DHTs), and Nat traversal.
  • Experience designing incentive systems and writing/deploying smart contracts in Ethereum.
  • A Master’s degree in Computer Science with a focus on computer networks.
  • A strong alignment to our principles: https://status.im/about/#our-principles


Bonus points if 

  • A PhD degree in an area related to computer networks.
  • Contributed to a blockchain-related, open source project.
  • In in the Ethereum community.
  • Experience with cryptography such as OTR, X3DH, Noise protocol.
  • Experience with Nim.
  • Experience with off-the-shelf networking stacks such as libp2p / devp2p.

[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].
