P2P Network Engineer / Core Developer

At Parity Technologies we maintain and create blockchain software: dealing with P2P networking, consensus algorithms, cryptography, databases, and decentralized applications can be expected.

We strive to write the fastest, lightest, and safest core technology in Blockchain and write lots of open-source code. Parity Technologies is based in Berlin and London, but remote work is possible for the right people and we are flexible on location.

We believe in giving back to the community and are looking for someone familiar with the open-source Rust ecosystem. You should be proficient in Rust, familiar with writing low and high-level code, confident with functional style programming, and knowledgeable in the (recent) space of computer networking research.

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 article on our blog about our development practices which you may want to read: (
