  • Define security standards and procedures; educate other team members.
  • Provide technical leadership in the area of blockchain technology.
  • We’re constantly growing and forming new teams; you will have the opportunity to lead as an engineer or transition into a manager role. 

What skills you will use:

  • 2+ years of smart contract development experience in Solidity (experience in other smart contract languages is an asset).

  • Experience in Solidity, OpenZeppelin standards, Web3, Truffle/Hardhat, the Graph, NodeJS, AWS, MySQL/Postgres, MongoDB/NoSQL. 
  • Experience in leading a team in completion of projects with agile methodologies.
  • Experience in smart contract auditing is a strong asset.
  • Familiar with cryptography and encryption methods. Experience with enterprise level key management solutions or projects is a strong asset.
