Parity is hiring a Rust Core Engineer - P2P networking

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.

About the position:

For this role you will be working mostly on off-chain protocols that power both the relaychain and parachains. Expect to be dealing with P2P networking and general implementation of the lower level (node side) details of a blockchain. In leaving classic server/client architectures behind, there are lots of interesting problems waiting for a solution. There is plenty of room for innovation, creating a performant, scalable and resilient P2P network out of untrusted and selfish nodes.

Some items on our roadmap: introduction of QUIC and WebRTC for Polkadot, improvements to our syncing and gossiping protocols, performance optimizations, improvements for attack resiliency, and research into alternate protocols. If you love thinking about edge cases, possible exploits, you can think out of the box and take pride in elegant code that is easy to understand, this role will be a very good fit.

Some of the existing code base can give you an idea of what to expect, and some of the documentation of the overall architecture can be found here.

Requirements:

• Experience with Rust, particularly writing high-performance high-security code.
• Knowledge of Bitcoin, Ethereum or other blockchain technologies.
• Familiarity with the Rust ecosystem.
• An interest in decentralized technology and Web 3.
• Knowledge of protocols such as TCP/UDP/QUIC/WebRTC

Nice to have:

For this role you can expect to mostly work on the node side of the code, which is implementing and improving off-chain protocols that make both the relaychain and parachains work. Deep knowledge in one of the following areas is especially appreciated:

• State of the art P2P networking research and technologies.
• Rust performance optimization and tuning.
• Experience implementing decentralized applications, including “Layer 1” and “Layer 2” approaches.
• Experience with debugging decentralized systems
• Experience with libp2p
• Knowledge of Grafana/Prometheus.

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
