3FA is building a new vertical in e-commerce through secure product identification. We work with top brands and marketplaces to build smart-contract enabled Near Field Communication (NFC) tags. Our IDs enable physical goods to inherit the non-fungibility, composability, and programability of NFTs, powering the next generation of the creator economy.

We are looking for an extremely talented founding engineer to help us pioneer this layer of secure commerce. Top notch communication skills are essential. Familiarity with hardware is helpful, but not neccesary.

  • 4+ years of experience in software development, with a strong emphasis on prototyping and new product development
  • 2+ years of smart contract development in Solidity on Ethereum or any EVM-based chain
  • Strong working knowledge of asymmetric cryptography, authentication and/or digital signatures
  • Demonstrated expertise in at least one modern programming language (C++, Rust, Go, Python, JS)
  • Proven experience in designing and implementing scalable and complex software architecture
  • Comfort with ambiguity and an ability to make progress independently
  • A passion for staying up-to-date with and learn about emerging technologies, trends, and best practices in blockchain

Nice to Haves

  • Familiarity with zK-Proofs, rollups, L2/L3s and data sampling
  • General understanding of various decentralized blockchains (Cosmos, Aptos, Sui, Starkware, Aztec) including the differences between each
  • M.S., or PhD in Computer Science, Cryptography, Computer Engineering, or the equivalent
  • Joining a talented, diverse and driven team
  • Meaningful equity ownership
  • Guidance from leaders and experts in commerce, compliance, and wallet integration
