Summary

The MetaMask Wallet API Platform Team

Currently the MetaMask Wallet API allows dApps to do things like: propose transactions to users, access the address of the users current account, use keys in MetaMask to help users encrypt and decrypt messages, propose to users that they sign specific messages, access the connected node provider and call all methods on the Ethereum RPC API, and to propose that users add and switch to a specific network. We enhance and expand this list of capabilities and build tools to help other teams build new capabilities themselves.

By improving and expanding this API, we can make entirely new types of decentralized user experiences possible. There is also much work to do to make this API accessible for the many new developers joining our space.

We are hiring engineers to join our Wallet API Platform team and help us build the platform on which the world’s most exciting dapps will be built.

What you’ll do

1. Build and maintain Wallet API infrastructure and tooling. 
2. Help to manage and govern a pipeline of proposed new APIs.
3. Work with partners and standards bodies across the Web3 ecosystem to shape wallet API standards.

Would be great if you brought this to the role

We are looking for a senior software engineer who is:

8. Interested in working with partners across the Web3 ecosystem on shared Wallet API standards

The Wallet API Platform team carries an important mission to craft and maintain the best API for developers so that MetaMask can continue to grow with the wider Web3 ecosystem.

The senior software engineer role is a critical part of this team. They would be responsible for creating and managing the API that all MetaMask developers are using. As web3 evolves, the API needs to evolve with the larger ecosystem. This requires a team of highly dynamic and agile software engineers to serve MetaMask’s developer community.

Because of the complexity and nascency of web3, most of our API have a very long lifecycle after being made publicly available. The engineer who takes on this role will be the guardian of a high-quality API with a long lifecycle in a rapidly evolving ecosystem. This engineer must have a long-term mindset when planning and designing the API as well as introducing any new major change.

6. 1 year of experience owning and managing unit, integration, end-to-end tests, and/or testing frameworks/strategies
7. 1 year of experience with JSON-RPC, Swagger, and or OpenAPI

Bonus points:
