Zero Knowledge (ZK) Jobs

This position can be remote or based near one of our offices in Berlin, Lisbon, or London. It's up to you to decide where you work best.

Parity Technologies builds core infrastructure for blockchains and Web 3.0 technologies. This means dealing with P2P networking, consensus algorithms, cryptography, databases, and decentralized applications. We strive to write the fastest, lightest, and safest core technology in Blockchain and write lots of open-source code.

We're looking for someone to work on our Substrate team across our entire node codebase, including topics like consensus, p2p networking, and our Cumulus project. In this role, you will be able to work on almost every component that makes up a Substrate node. We have planned some larger refactoring of the Substrate node which is planned to be done in iterations on the current code base. In your role you will be helping with these refactorings while building new stuff in parallel.

Parity works in a very flat hierarchy with lots of autonomy and high levels of personal responsibility, and we try to mimic an open-source workflow in much of what we do. We have an older article on our blog about our development practices which you may want to read.

Here are a few links to the codebase and relevant documentation you'd be working on:

• Substrate Github
• rust-libp2p

Bastian Köcher (link to Github) is the lead for the Substrate SDK Node team.

Requirements:

• Experience with current blockchain technologies and landscape.
• Experience with analyzing issues in a huge and unknown code base and then solving these issues.
• Theoretical background in distributed systems, such as consensus algorithms, as well as cryptographic fundamentals.
• Strong knowledge of a modern systems programming language, such as Rust, C++ or Go and willing to learn Rust.
• An interest in decentralized and privacy technology and Web3.

Nice to have:

At Parity Technologies we write software across the whole blockchain stack and as a developer you can be expected to work on any of these things, but deep knowledge in one of the following areas is especially appreciated.

• Writing and performance tuning databases.
• Cryptography, including multi-party computation or zero knowledge proof systems.
• Consensus algorithms, especially as used within the blockchain space.
• Implementing compilers, especially with a Wasm focus.
• Implementing decentralized applications, including “Layer 1” and “Layer 2” approaches.

Benefits:

• Competitive salaries and benefits.
• Opportunity to become an expert in latest blockchain technologies.
• Working at Parity means focusing on stuff that matters: building cutting-edge technology for a better and more decentralized internet. Our teams enjoy a high degree of freedom and autonomy to achieve that goal.
• Because we value initiative and learning, we've defined a generous personal improvement budget to attend conferences or skills courses of your own choosing. We think you know what's best for you!
• Parity is a diverse company with people from various countries and we will support you with German or English language courses where needed (and desired).
• We have a remote-friendly company setup.
• Bringing the team together is something we value a lot and we have regular company retreats
