Nice to have:

  • Experience with blockchain protocols, whether it be usage of a blockchain API, knowledge of how a blockchain operates, or any other experience
  • Experience with blockchain-related libraries, such as Web3.js and/or Ethers.js
  • Experience with documenting a large codebase, both for internal and user-facing components
  • Familiarity with open-source software principles
  • Experience writing software from a technical specification or a reference implementation
  • NPM publishing experience

What WalletConnect offers:

  • Fully remote position with flexible timezone (CET/EST preferred)
  • Competitive salary
  • Company equity

A blockchain engineer is responsible for developing and implementing blockchain-based solutions

Here are some of the key responsibilities of a blockchain engineer:

  1. Design and develop blockchain protocols: The blockchain engineer is responsible for designing and developing blockchain protocols, including consensus algorithms, data structures, and security protocols.
  2. Develop decentralized applications: The blockchain engineer builds decentralized applications (DApps) that run on top of blockchain networks.
  3. Write smart contracts: Smart contracts are self-executing contracts that run on blockchain networks. The blockchain engineer writes smart contracts using programming languages such as Solidity.
  4. Implement and test blockchain solutions: The blockchain engineer implements and tests blockchain solutions to ensure they work as intended.
  5. Stay up-to-date with the latest blockchain technologies: The blockchain industry is constantly evolving, and a blockchain engineer must stay up-to-date with the latest trends and technologies.
  6. Collaborate with other developers: The blockchain engineer collaborates with other developers, such as front-end developers, to integrate blockchain solutions into larger software applications.
  7. Ensure security and scalability: The blockchain engineer must ensure that the blockchain solution is secure and scalable to handle a large number of users and transactions.
