About Unlink

Unlink's mission is to build the last missing piece of the blockchain puzzle: Privacy. We're rendering existing blockchains private, solving one of the most fundamental challenges preventing mass adoption of decentralized technology.

About the role

We are looking for a Senior Frontend Engineer to lead the end-to-end user experience for privacy on-chain: web app, browser extension, and mobile. You'll own major surfaces from first principles and will build products on top of Unlink's infrastructure.

What you'll do

• Ship flagship user experiences across Web (React/Next.js), Extension (WXT/Plasmo), and Mobile (React Native/Expo).

• Design the privacy UX of tomorrow: approvals & signing, fee abstraction, private own/send/receive flows, recovery, and explainability.

• Raise the engineering bar: testing (unit/e2e), performance budgets, observability (Sentry/PostHog), CI.

• Collaborate like an owner: scope MVPs, cut scope smartly, and iterate with designers & backend/crypto engineers.

You may be a good fit if you

• Have 5+ years building polished product UIs with TypeScript + React (Next.js preferred)

• Pay attention to detail and have strong UI/UX intuition

• Ship quickly with high standards and can reduce complex systems to simple user journeys

• Are comfortable owning features end-to-end: scoping → implementation → QA → metrics → iteration

• Communicate crisply and enjoy collaborating with design and low-level engineering teams

• Care deeply about privacy and understand why this work matters

Bonus points

• Built wallets or Web3 frontends that handle real user funds

• Shipped browser extensions with complex state management

• Developed cross-platform mobile apps with React Native for iOS/Android

• Deep understanding of frontend security best practices (key management, secure storage, XSS prevention)

• Contributed to open source or shipped side projects in the crypto/privacy space

What we offer

• High-impact work: Build the core of our product and shape its direction. You won't be a cog in a machine.

• Competitive salary with equity: A significant ownership stake in what we're building together.

• Ownership culture: Meritocracy is at our core. You'll drive major decisions and own your domain completely.

• Team & culture: Join a family of talented engineers who are passionate about blockchains and privacy.

• Growth: Events, conferences, and off-sites throughout the year to learn and connect.

Come work with us

Unlink is not a research lab. We solve hard problems to create concrete value for humanity. We're building the infrastructure that will make privacy on blockchains accessible to everyone.
