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 100+ 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 are happy to pay in either 100% fiat or any mix of fiat and/or crypto. For more information regarding benefits at Status: https://people-ops.status.im/tag/perks/

Hiring process

The hiring process for this role will be:

• Interview with Angel from our Talent team
• Interview with team member from the Vac team
• Pair programming task with the Vac team
• Interview with Oskar, the Program lead
• Interview with Jacek, Research Lead

The steps may change along the way if we see it makes sense to adapt the interview stages, so please consider the above as a guideline.
