Blockchain Developer – Cross Chain Messaging

Experience with current blockchain technologies and landscape. Opportunity to become an expert in latest blockchain technologies....

Note to applicants: our headquarters is located in Berlin, but Parity has teammates distributed across the EU and beyond. Remote working arrangements are common and possible; we’re happy to discuss this more during the recruiting process!

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.

Your tasks
will revolve around working on a specific part of polkadot protocol: messaging. It is a wide area which may include tasks that touch on blockchain cryptography, networking, WebAssembly state transition functions, and more.


  • Experience with current blockchain technologies and landscape.
  • 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:

  • Knowledge/work on state of the art P2P networking research and technologies.
  • Experience writing and performance tuning databases.
  • Cryptography knowledge, including multi-party computation or zero knowledge proof systems.
  • Consensus algorithms knowledge, especially as used within the blockchain space.
  • Experience implementing compilers, especially with a Wasm focus.
  • Past work implementing decentralized applications, including “Layer 1” and “Layer 2” approaches.


  • 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 (or will have, pending the Covid pandemic)
