Joy Network Jobs

We’re building software that makes it easy for the most innovative blockchain applications to launch their own ultra-performant blockchains, enabling applications to own their ecosystem, scale to millions of users, and provide a superior user experience to their players.

As a Senior Protocol Engineer, you will:

• Help architect the blockchain node that comprises the backbone of our software offering. You’ll be working on the cutting edge of blockchain scaling, building new kinds of layer twos.
• Make improvements or extensions to the virtual machine that runs Ethereum smart contract code ie custom precompiles
• Evaluate database backends, networking libraries, and other tools and help make decisions as to which should be included in our stack
• Write efficient and secure EVM smart contracts in solidity
  

You might be a fit for this role if you...

• Have 4+ years of engineering experience
• Have a deep knowledge of Go, Rust or similar languages
• Have built Ethereum “dapps” with Solidity or Yul
• Have experience working with distributed or embedded systems before
• Love writing fast, well-optimized, well-tested, clean code
• Are confident with performance optimization, identifying bottlenecks and scalability concerns
  

Bonus points if you...

• Are familiar with how blockchains like Ethereum or Bitcoin work under the hood
• Are up-to-date with Ethereum scaling solutions such as sidechains or rollups
• Have implemented or used a consensus algorithm (eg. Paxos/Raft, pBFT, tendermint, ...) in the past
• Have an understanding of cryptography primitives, such as hash functions or digital signatures
• Have significant open-source contributions, especially in blockchain clients/node software, databases, networking, or programming languages/frameworks
