Cryptography Specialist Engineer (Snaps)

About MetaMask

We’re building for a future where the internet and world economy empowers people through interactions based on consent, privacy, and free association. Where both communities and individuals flourish. To accomplish that, we’re working hard to make web3 accessible for everyone.

MetaMask is both a crypto wallet and a gateway to the decentralized web. Our tools help people create communities, play video games, access financial services, make payments, invest in assets, protect against economic turmoil, and more. Our browser extension and mobile platforms meet the needs of millions of users and developers across the world.

Originally a humble key manager, today MetaMask serves over 30 million monthly active users as a decentralized application development platform, an aggregator of decentralized cryptocurrency exchanges, and a decentralized identity manager.

About the Team

MetaMask Snaps is the next phase in MetaMask’s evolution. Currently available via MetaMask Flask, our developer preview build, it allows MetaMask, our partners, and the entire web3 community to add radical new functionality to MetaMask.

Install MetaMask Flask and check out live examples like Bitcoin, Filecoin, and a password manager. We aim to make adding entirely new networks and use cases as easy as it is to write a Dapp today.Watch our tech talks at ETHDenver and ETHRio and get a feel for the excitement and possibilities of MetaMask Snaps.
