About the Role

Neftify is looking to hire a blockchain engineer willing to get their hands dirty daily architecting protocols, writing, and testing smart contracts. As one of the first hires, you will work directly with everyone on the team to develop Neftify's infrastructure. You will be responsible for ensuring consistent, high-quality codebases, technical specifications, deployment scripts, and more:

  • Build and deploy smart contracts that meet rigorous audit requirements
  • Drive standardization in NFTs across blockchains, including by designing public metadata standards
  • Plan for and support blockchain infrastructure
  • Build backend services to connect Neftify with the blockchains we integrate
  • Work closely with the team to define crypto strategies and roadmaps
  • Architect smart contract protocols
  • Drive the standardization in crypto protocols by designing and defining interfaces


  • 1-2 years of experience with Solidity development
  • Experience with a development suite, such as Hardhat, Dapp, Brownie or Truffle
  • Experience with contract libraries, such as Dappsys and OpenZeppelin
  • A deep understanding of blockchain fundamentals, common vulnerabilities, and the EVM
  • Know when to create abstractions vs. one-off methods
  • An awareness of different products and services that large DeFi projects like Uniswap and Maker are offering, and how they are implemented in terms of business logic, technology, systems, and software architecture
  • A desire to keep up with emerging trends in the Ethereum and blockchain technology space
  • Native-level fluency in English (spoken and written)

FAANG experience, college pedigree, and age are not factors that we take into consideration. Track record and a history of building cool shit is all we care about.
