Zero-Knowledge Jobs in Crypto, Web3 & Blockchain

About Codex

We’re a diverse team of experienced researchers and engineers scattered around the world working at the intersection of P2P networks and bleeding-edge Zero Knowledge technology. We’re building the next generation storage engine that attempts to “untie the knot” of incentivized storage. Our goal is to deliver a more advanced decentralized storage protocol that pushes the state of the art of decentralized storage solutions forward. We’re looking for an experienced p2p networking engineer with hands-on experience designing and implementing state of the art networking protocols and distributed systems.

Key responsibilities

• Research,design and implement proof systems for remote auditing schemes
• Implement zk friendly hashing functions
• Familiarity with state of the art proving backends such as arkworks, bellman, etc…
• Write specifications and design documentation
• Document and communicate research findings to the wider community
• Perform security analysis, measure performance of and debug circuits

You ideally will have

• Very strong academic or engineering background (PhD-level or equivalent in industry); relevant research experience
• Experience with low level/strongly typed languages (C/C++/Go/Rust or Java/C#)
• Experience with Open Source software
• Deep understanding of Zero-Knowledge proof systems and corresponding tooling 
• Keen communicator, eager to share your work in a wide variety of contexts, like internal and public presentations, blog posts and academic papers.
• Experience in, and passion for, blockchain technology
• A strong alignment to our principles: https://status.im/about/#our-principles

Bonus points

• Experience and interest in decentralized storage and p2p technologies
• Experience designing and implementing zk-friendly hashing functions
• Experience with WebAssembly tooling

About Status 

Status is building the tools and infrastructure for the advancement of a secure, private, and open web3.  With the high level goals of preserving the right to privacy, mitigating the risk of censorship, and promoting economic trade in a transparent, open manner, Status is building a community where anyone is welcome to join and contribute. As an organization, Status seeks to push the web3 ecosystem forward through research, creation of developer tools, and support of the open source community.  As a product, Status is an open source, Ethereum-based app that gives users the power to chat, transact, and access a revolutionary world of DApps on the decentralized web. But Status is also building foundational infrastructure for the whole Ethereum ecosystem, including the Nimbus ETH 1.0 and 2.0 clients, the Keycard hardware wallet, and the Waku messaging protocol (a continuation of Whisper). As a team, Status has been completely distributed since inception.  Our team is currently 150+ core contributors strong, and welcomes a growing number of community members from all walks of life, scattered all around the globe.  We care deeply about open source, and our organizational structure has minimal hierarchy and no fixed work hours. We believe in working with a high degree of autonomy while supporting the organization's priorities.

Who are we? 

Vac builds public good protocols for the decentralized web. We do applied research based on which we build protocols, libraries and publications. Custodians of protocols that reflect a set of principles - liberty, privacy, etc. You can see a sample of some of our work here: Vac, Waku v2 and Ethereum Messaging, Privacy-preserving p2p economic spam protection in Waku v2, Waku v2 RFC. Our attitude towards ZK: Vac <3 ZK. The role? This role will be part of a new team that will make a provable and private WASM engine that runs everywhere. As a compiler engineer, you will be responsible for researching, designing, analyzing and implementing zero-knowledge circuits that allow for proving private computation of execution in WASM. This includes having a deep understanding of relevant ZK proof systems and tooling (zk-SNARK, circom, Plonk/Halo 2, zk-STARK, etc), as well as different architectures (zk-EVM Community Effort, Polygon Hermez and similar) and their trade-offs. You will collaborate with the Vac Research team, and work with requirements from our new Logos program. As one of the first hires of a greenfield project, you are expected to take on significant responsibility, while collaborating with other research engineers, including protocol engineers and senior Rust engineers. Key responsibilities 

Analyze and implement proof systems and architectures for private computation Design and implement zero knowledge circuits in Rust Perform security analysis, measure performance of and debug circuits Write specifications and communicate research findings through write-ups Break down complex problems, and know what can and what can’t be dealt with later

You ideally will have 

Experience with compilers, VMs, domain-specific languages Familiarity with Zero-Knowledge Proofs (zk-SNARK, circom, Plonk/Halo2, zk-STARK), elliptic curve cryptography, and circuit design Experience with low level/strongly typed languages (C/C++/Go/Rust or Java/C#) Very strong academic or engineering background (PhD-level or equivalent in industry); relevant research experience Keen communicator, eager to share your work in a wide variety of contexts, like internal and public presentations, blog posts and academic papers. Experience with Open Source software Experience in, and passion for, blockchain technology A strong alignment to our principles: https://status.im/about/#our-principles

Bonus points if 

Experience with hardware instruction set architectures Experience in provable and/or private computation (zkEVM, other ZK VM) Rust Zero Knowledge tooling Experience with WebAssembly

[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]. Compensation We pay a competitive salary based on experience, plus a grant of Status Network Tokens vesting over a three-year period.
