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 and familiar with writing low and high-level code, a functional >
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.
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.
Nice to have:
At Parity Technologies we write software across the whole blockchain stack and 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.
- State of the art P2P networking research and technologies.
- Experience writing and performance tuning databases.
- Cryptography.
- Experience implementing consensus algorithms.
- Rust performance optimization and tuning.
- Deep knowledge of and ability to write compilers (especially with a Wasm focus).
- Blockchain bridges.
- Experience implementing decentralized applications, including “Layer 1” and “Layer 2” approaches.
Benefits:
- Working at Parity means focusing on the stuff that counts: building some of the most cutting-edge technology for the future web. Our teams enjoy a high degree of trust, 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
Not a perfect match to our requirements? We're happy to receive your application anyways and hear how you think you can help us achieve our mission.

What is the meaning of Layer 2?
Layer 2 in the context of cryptocurrency and blockchain technology refers to a secondary framework or protocol that is built on top of an existing blockchain system (the main chain or Layer 1)
The primary purpose of Layer 2 solutions is to solve the scalability and speed issues that many blockchains face, especially those that have become popular and heavily used, like Ethereum
Here are the key aspects of Layer 2 solutions:
- Scalability Enhancement: They help in scaling the main blockchain by handling transactions off the main chain. This reduces the burden on the main chain, allowing for faster and cheaper transactions.
- Types of Layer 2 Solutions: There are various forms of Layer 2 solutions, including state channels, sidechains, plasma chains, and rollups. Each has its own mechanism for interacting with the main chain and handling transactions.
- State Channels: These involve two parties engaging in numerous transactions outside of the main chain, which are then consolidated into a single transaction. This is especially useful for situations where multiple transactions occur between the same parties.
- Sidechains: These are separate blockchains that are connected to the main chain via a two-way peg. They operate independently and can have their own consensus mechanisms but are secured by the main chain.
- Plasma Chains: Plasma chains are similar to sidechains but with a more hierarchical structure. They report back to the main chain regularly and are optimized for mass transaction handling.
- Rollups: Rollups process and store transaction data on a sidechain but post transaction data to the main chain. They come in two varieties: optimistic rollups and zk-rollups, each with its own method of transaction verification.
- Security Considerations: While Layer 2 solutions are generally secure, they can have different security models compared to the main chain. This is an important consideration for users and developers.
- Impact on User Experience: For end-users, Layer 2 solutions can greatly improve the experience by reducing transaction fees and increasing transaction speeds.
- Adoption and Development: Many blockchain projects are actively developing Layer 2 solutions to enhance their networks. This is an ongoing area of innovation in the blockchain space.
