DEV Jobs at Sismo

Sismo is a privacy-preserving login system based on blockchain infrastructure, decentralized identities (DID) and Zero Knowledge (ZK) technology.

Sismo is developing the Sismo Attestation Protocol which allows anyone to generate privacy-preserving attestations from their web3 accounts (e.g BAYC NFT Ownership). Sismo attestations can be stored as NFTs on Ethereum/EVM chains and are compatible with web2 and web3 applications as an access control and reputation tool.

Our team of 7 crypto-native builders has been working on Ethereum since 2015 (ex Aave, Sandbox, Kleros, ConsenSys). We recently raised $10m from some of the top blockchain teams (Optimism, Starkware, Curve, Axie Infinity, Nansen, etc..), a strong mix of web3 investors (Delphi, IDEO, Framework, Fabric) and successful web2 projects (Founder of Product Hunt, Naval Ravikant, GFC).

At Sismo, you will be exposed to everything crypto has to offer; from comprehensive training to in-person conferences and hackathons to good community memes and so much more.

The Sismo team prioritises privacy, decentralization and developing ZK tech that will power the future of the decentralized web. We are deeply committed to this mission and believe cryptography and blockchains will benefit billions of people by enabling users to take ownership of their digital identity.
