About MetaMask

MetaMask aims to democratize access to the decentralized web. We are pursuing this mission through our desktop browser extension ( ) and our mobile app ( ), both of which enable millions of users and builders to work with the Ethereum blockchain.

MetaMask includes a secure identity vault, providing a user interface to manage your identities on different sites and sign transactions and messages on decentralized networks. This is paired with an API that allows developers to connect their applications to decentralized networks and propose transactions to users.
We're Hiring

We are looking for our next teammate, a Senior Software Engineer who can bring passion and focus to the development of the apis, tools and systems we build for developers.

We are currently entering a critical phase of development for the MetaMask plugin system known as "Snaps" . This system provides developers with an API to extend the functionality of MetaMask, enabling developers to provide users (and other developers) with access to new networks, signing strategies, business logic and more.

Joining our team at this time will be an opportunity to be at the forefront of this project and other initiatives to empower the builders of the decentralized web.

  • Be proficient and thoughtful with asynchronous and synchronous communication, giving and receiving feedback, and working independently and with a team

  • Bring respect, patience, and empathy to every interaction and relationship with coworkers and the community
