Job description

Location: EU or Remote (excluding France)

Consensys is the leading blockchain and web3 software company founded by Joe Lubin, CEO of Consensys and Co-Founder of Ethereum. Since 2014, Consensys has been at the forefront of innovation, pioneering technological developments within the web3 ecosystem.

Through our product suite, including the MetaMask platform, Infura, Linea, Diligence, and our NFT toolkit Phosphor, we have become the trusted collaborator for users, creators, and developers on their path to build and belong in the world they want to see.

Whether building a dapp, an NFT collection, a portfolio, or a better future, the instinct to build is universal. Consensys inspires and champions the builder instinct in everyone by making web3 universally easy to use and develop on.

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

You’ll get to work on the tools, infrastructure, and apps that scale these platforms to onboard one billion participants and 5 million developers. 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 builders 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 empower 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.

MetaMask Card, a newly formed team, is on a mission to integrate crypto with traditional payment systems. As a Software Engineer on our team, you'll be at the forefront of developing and enhancing features that make using crypto assets outside the crypto universe seamless and intuitive.

What you’ll do

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

This includes work related to the MetaMask Card offering and how we can facilitate the integration of web3 with traditional payment methods. Many activities focus on user experience (mobile / web / browser extension) and API integration.

You will be responsible for developing new features and managing various partners, payment methods, and crypto assets. Your goal is to streamline the integration process while reducing technical debt. You will also engage in research to conceive innovative features.

Ideal candidate

You are well-acquainted with the Ethereum ecosystem and adept at building products across mobile, web, and backend platforms. With a keen sense of user experience, you are dedicated to enhancing it at every turn.
