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

The most fundamental role that MetaMask plays for 30+ million users is to help them manage their private keys and take action with those keys. Our first and most well known strategy for this is the Secret Recovery Phrase (aka the “seed phrase”). MetaMask stores the users SRP on their machine, and from it deterministically generates private keys and accounts. 

Our next innovation in this area was integration with hardware wallets. By storing their SRP on external hardware design for this purpose, users are able to be more secure than their machine while enjoying the convenience and UX of MetaMask.

Over the past six months, we have expanded the number of hardware wallets we integrate with and have fixed some long standing pain points in hardware wallet UX. However, the development of account and key management solutions at MetaMask is just getting started.

While our roadmap is always evolving, here are some of the areas of improvement and innovation that this team will bring to MetaMask:

  • Adding new account types to MetaMask (e.g. smart contract based accounts, multi-sigs, etc)
  • Seed phrase back-up solutions (e.g. cloud-based backups, password manager integrations)
  • Hardware wallet UX enhancements (smoother onboarding flows, easier management of multiple hardware devices)

About the Role

We are looking for a senior engineer who would be excited to bring technical leadership to these areas of work and help propose and champion other innovative key management features.

What you’ll do:

  • Be passionate about the technical and UX challenges involved in account and key management for a blockchain wallet
  • Work on both our mobile and extension products with equal enthusiasm
  • Lead technical and architectural decisions related to UI, APIs and modules necessary for MetaMask’s current and future key management solutions
  • Improve our key management related code through effective review of pull requests, triaging and analysis of GitHub issues, auditing and refactoring the codebase, and testing
  • Lead the technical security assessment of all new account and key management features to ensure MetaMask continues to be an extremely safe experience
  • Proactively contribute to team discussions about technical issues, sprint and roadmap planning, and improving team processes
  • Be proficient and thoughtful with asynchronous and synchronous communication, giving and receiving feedback, and working independently and with a team
  • Support their teammates’ performance and growth
  • Be successful working within a fully remote environment
  • Bring respect, patience, and empathy to every interaction and relationship with coworkers and the community
  • Bring hustle, enthusiasm, heart and a love of shipping code and fixing bugs to their work

Who we’re looking for:

  • JavaScript and TypeScript
