Senior Fullstack Engineer, MetaMask



Canada · United States · Remote
Posted on Saturday, April 27, 2024

Our mission is to unlock the collaborative power of communities by making Web3 universally easy to use, access, and build on.

Working with Consensys puts you at the forefront of an evolving paradigm, transforming our society for the better. We fundamentally believe blockchain is the next generation of technology that can lay the foundation for a more just and equitable society.

Blockchain tech is just over 10 years old. Ethereum itself is still a toddler and we’re far from reaching our full potential. You’ll get to work on the tools, infrastructure, and apps that scale these platforms to billions of users.

You’ll be constantly exposed to new concepts, ideas, and frameworks from your peers, and as you work on different projects — challenging you to stay at the top of your game. You’ll join a network of entrepreneurs and technologists that reaches the edge of our ecosystem. Consensys alumni have moved on to become tech entrepreneurs, CEOs, and team leads at tech companies.

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 around the world.

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.

What you’ll do

We are looking for a Software Engineer who's eager to pioneer the next wave of crypto adoption by developing innovative features for MetaMask Ramps and refining our current offerings.

In this role, you'll immerse yourself in the complete cycle of buying and selling crypto assets, closely collaborating with fellow engineers. This journey requires a deep understanding of user needs and navigating the integration challenges our partners face across both front and back ends.

You'll be responsible for developing new features and managing various partners, payment methods, and crypto assets. Your goal is to streamline the integration process while curbing the growth of technical debt. Concurrently, you'll engage in research to conceive innovative features.
