Senior React Native Developer

Zefi , Anywhere (RemoteOK) · zefi.io · Full-time employment · Programming

Backed by YCombinator and part of their W20 batch, we're building a native mobile app for global users to interact and do more with their crypto assets. Decentralized Finance or DeFi is an ecosystem comprised of applications built on decentralized networks, permissionless blockchains, and peer-to-peer protocols for the facilitation of lending/borrowing or trading with financial instruments.

The core principle is to provide a new, permission less financial ecosystem without a central authority. This allows for lending and borrowing in a decentralized manner. The user acts as their own custodian, maintaining full control of their assets while granting access to financial services.



We are looking for a React Native developer interested in building performant mobile apps on both the iOS and Android platforms. You will be responsible for architecting and building these applications, as well as coordinating with the teams responsible for other layers of the product infrastructure. Building a product is a highly collaborative effort, and as such, a strong team player with a commitment to perfection is required.

<h3>Responsibilities</h3>
  • Build pixel-perfect, buttery smooth UIs across both mobile platforms.
  • Leverage native APIs for deep integrations with both platforms.
  • Diagnose and fix bugs and performance bottlenecks for performance that feels native.
  • Reach out to the open source community to encourage and help implement mission-critical software fixes—React Native moves fast and often breaks things.
  • Maintain code and write automated tests to ensure the product is of the highest quality.
  • Transition existing React web apps to React Native.
<h3>Skills</h3>
  • Firm grasp of the JavaScript {{and TypeScript or ClojureScript}} language and its nuances, including ES6+ syntax
  • Knowledge of {{functional or object-oriented}} programming
  • Ability to write well-documented, clean Javascript code
  • Rock solid at working with third-party dependencies and debugging dependency conflicts
  • Familiarity with native build tools, like XCode, Gradle {{Android Studio, IntelliJ}}
  • Understanding of REST APIs, the document request model, and offline storage
  • Experience with automated testing suites, like {{Jest or Mocha}}
