Senior Front-End Developer · Entravision | JobCheckPoint

Adwake is a tech-enabled services company powered by Entravision. We are a dynamic technology company building a high-availability offerwall platform that connects users with engaging opportunities. Our mission is to deliver seamless, high-quality experiences across web and mobile devices, and we’re looking for a Senior Frontend Developer to join our dynamic team.

As a Senior Frontend Developer, you will play a pivotal role in designing, developing, and maintaining our web and mobile applications. You’ll work closely with cross-functional teams, including product and backend engineers, to deliver responsive, performant, and visually appealing user interfaces. Your expertise in React and React Native will drive the creation of cutting-edge solutions that delight our users.

What You’ll Do:

Lead the iOS build of our React Native app, working closely with product and backend.

Configure and integrate native SDKs on iOS: Firebase (messaging/APNs, analytics, App Check), AppsFlyer, AppLovin MAX, Google Sign-In, the Facebook SDK and Intercom.

Implement App Tracking Transparency, SKAdNetwork, privacy manifests, deep links and universal links.

Design iOS alternatives for features built on Android-only APIs, with product.

Write native Swift or Objective-C modules where React Native libraries fall short.

Build the iOS release pipeline in CircleCI with fastlane: code signing, TestFlight and App Store Connect.

Own App Store submissions and App Review, including the guidelines that apply to rewards and incentive apps.

Keep shared code platform-agnostic so Android and iOS stay in sync.

Maintain testing on both platforms with Jest and Maestro end-to-end tests.

Review code and share iOS knowledge with the team.

What you need to have:

5+ years of professional mobile or frontend experience, including 3+ years of React Native.

At least one React Native app shipped to the App Store and maintained in production.

Strong knowledge in TypeScript and JavaScript.

Hands-on iOS tooling: Xcode, CocoaPods, signing and provisioning, TestFlight, App Store Connect.

Experience integrating third-party native SDKs (attribution, ads, push, analytics) in React Native.

Working knowledge of Swift or Objective-C for native modules and debugging.

Solid understanding of App Store Review Guidelines, ATT and Apple’s privacy requirements.

Testing experience with Jest plus a mobile end-to-end framework (Maestro, Detox or similar).

Strong problem-solving skills and comfort in a fast-paced environment.

Nice-to-Have:

Experience with rewards, offerwall, gaming or ad-monetised apps and how they fare in App Review.

WebView-based hybrid apps (JS-to-native messaging, cookie and session handling).

React web experience (React Query, MUI), to help on the web app.

CI/CD for mobile (CircleCI, fastlane, Firebase App Distribution).

Google Cloud and Firebase.

Sentry or similar crash reporting.

Why Join Us?

Work on a high-impact, high-availability platform serving millions of users.

Collaborate with a talented and passionate team in a fast-paced, innovative environment.

Hybrid working model, with possibility of working remotely.

Opportunities for professional growth and hands-on experience with cutting-edge technologies.
