Money is moving onto the internet, and the shift has a name: Open Money. This is money that is open, portable, agentic, and owned by you. MetaMask spent the last ten years building it; with 100M+ downloads, users in ~190 countries, and trillions in cumulative transaction volume, it's the most trusted self-custodial financial platform on the internet. Now we're building the operating system for your money: one place to hold, move, grow, and use anything you own. Join a remote-first, global team rebuilding how money works: a problem that touches everyone, every day.

About this role

We’re looking for a Senior Design Engineer to join the Consensys Design team, supporting MetaMask - the most used wallet in crypto. This is a rare opportunity to bring beautiful, intuitive experiences to millions of users engaging with decentralized applications and Web3 technologies every day.

As a Senior Design Engineer, you'll turn complex flows into simple and delightful experiences across our app and browser extension. Working closely with designers, engineers, and product managers, you'll take ideas from prototype to production - sweating the animations, haptics, and micro-interactions that make every interaction feel considered, not just functional. You'll build in React and React Native with an eye for pixel-perfect execution, contribute to our design system, and build agentic workflows that help the team move faster without cutting corners. If you love making complex things feel simple, care about craft down to the smallest detail, and want that craft in the hands of 30M+ users, this role is for you.
What You'll Do

In one sentence: Make MetaMask interactions feel intuitive, fast, and delightful - across mobile and extension

- Build pixel-perfect interfaces in React and React Native, with obsessive attention to detail.

- Design and implement animations and micro-interactions that make every tap feel considered.

- Translate Figma designs into accessible, production-ready experiences with minimal handoff friction.

- Build agentic workflows and tooling that speed up design-to-code and day-to-day engineering work.

- Grow the MetaMask design system: reusable, accessible components built to scale across platforms.

- Move from idea to prototype fast and validate with real users.

- Push for craft everywhere - the small animation nobody asked for that makes an interaction click.

Key Experience

- Portfolio demonstrating delightful, polished interfaces and interactions - not just static screens, but the motion and detail that make them feel alive.

- Proven track record shipping high-traffic, consumer-facing products in React and React Native.

- Fluency in modern JS/TypeScript and cross-platform frontend architecture: performance, accessibility, and scalable UI patterns

- An eye for interaction design and motion - you know when animations and haptics earn their place and when they're just noise.

- Strong Figma literacy - you read a design file like code.

- Good judgment about when to polish and when to ship.

- Comfortable working autonomously across a distributed, global team

- Hands-on experience with crypto wallets, blockchain, or related Web3 products.

Don't meet all the requirements? Don't sweat it. We’re passionate about building a diverse team of humans and as such, if you think you've got what it takes for our chaotic-but-fun, remote-friendly, start-up environment—apply anyway, detailing your relevant transferable skills in your cover letter. While we have a pretty good idea of what we need, we're ready for you to challenge our thinking on who needs to be in this role.
