Our mission is to abstract away all technical complexity, empowering developers to create accessible end-user experiences. We believe every internet user should have access to apps and experiences onchain without the headache of traditional self-custody wallets—and the hassle of navigating siloed blockchain networks. After setting the standard for wallet abstraction, Magic is on a mission to pioneer the next phase of abstraction: chain abstraction. With so many L1s, L2s and L3s entering the space in addition to new VMs, it’s never been more crucial to solve identity and liquidity fragmentation that spans across chains—this is how we’ll achieve true interoperability and seamless user experiences. Magic is building a unified, cross-chain network that will maximize efficiency and accessibility for developers and users alike. The Role Magic’s frontend team is responsible for building high-quality, innovative and performant experiences that delight our users.

Architecture: you will collaborate with engineering peers across the organization to push forward measurable improvements to the architecture of all Magic systems, including our SDK and UI/UX components. You will collaborate with peers in writing and reviewing technical designs taking special attention to security and quality of proposed solutions.  Federated Identity Service: you will play a pivotal role in shaping the backbone of our federated identity services architecture accessible through our SDK. You will lead initiatives to build out new functionality, improve existing features, and push service quality to the highest level.

This position is fully remote, and we'd love to see applicants across the US and Canada, with a preference for hybrid NYC talent. Unfortunately, we are unable to sponsor or take over sponsorship (ex., H-1B transfer) of employment visas at this time, and applicants must be authorized to work for any employer in the US or Canada. You will:

Empathy with customers, developers, and users who rely on our services A passion for improving developer experience and reducing user friction Attention to detail and the creativity to bring static mock-ups to life Knowledge of security best practices, especially the pitfalls that come with developing secure applications for the web An ability to write well-designed, testable, and efficient code while balancing feasibility with ambition Knowledge and expertise in following the Agile Software Development Life Cycle Strong opinions, loosely held

You have:

Ideally 6-8 years experience of working within an agile software development team Direct experience working within web3 (including freelancing or side projects) Strong passion for Web3 and blockchain knowledge, ideally Ethereum Experience in ES6+ JavaScript (TypeScript experience preferred) Experience in CSS preprocessors like LESS or SCSS  Experience with Next.js, React, React Hooks, and Redux Strong interpersonal skills that demonstrate empathy and the ability to distill technical concepts into digestible pieces Working knowledge of webpack or similar tooling

Bonus points:

Strong technical writing skills Experience developing open source software and developer tools Keen awareness of application security, and knowledge of Open Web Application Security Project(OWASP) top 10 vulnerabilities Identity and authentication experience Wallet and/or web3 experience (domain understanding)

Developer Experience (DevX) is responsible for making sure all engineers at Coinbase build high-quality products while being productive and engaged. We do this by providing infrastructure, libraries, frameworks, and tooling to make it easier and faster to build high quality applications.Within Developer Experience, we organize into “pods” that focus on different specializations.

The “UI Systems” guild builds a state-of-the-art design system and tooling to guide engineers towards building high quality, consistent, delightful, and accessible UIs for both web and mobile.

What we look for in you:

  • You have at least 2+ years of experience in developing web apps and shipping user-facing features with JavaScript and modern, component-based JS frameworks like React.
  • You've developed and shipped user-facing features using component-based UI frameworks.
  • You’re familiar with current trends and best practices in front-end architecture, including performance, security and usability.
  • You’re familiar with product and design lifecycles, and collaborating closely with designers, engineers, and product managers.
  • You write high quality, well tested code to meet the needs of your customers.

Nice to haves:

  • Experience with AI, Codegen, ML, Figma
  • Experience building Design Systems (look for keywords such as React, CSS, CSS-in-JS, Tailwind, Linaria, Storybook, etc.). Experience with UI animation (Lottie, Rive). Experience with tools for design, accessibility or visual regression testing (Figma, Framer, Percy, BrowerStack). Experience with React Native, or from companies known to use React Native (Meta, Microsoft, Shopify, Discord, Expo).

Pay Transparency Notice: Depending on your work location, the target annual salary for this position can range as detailed below. Full time offers from Coinbase also include target bonus + target equity + benefits (including medical, dental, vision and 401(k)).
