Job description

Role overview

Own mobile product development from implementation through release, building applications for drivers on iOS and Android. The work centers on dependable offline-first workflows for trips, delivery confirmation, and location tracking, while also covering mobile infrastructure, supporting backend services, and occasional web product work.

Responsibilities

• Build and ship a React Native driver app for both iOS and Android, including trip workflows that can operate offline.
• Implement delivery confirmation using camera capture and signatures, plus background GPS tracking designed to run through a full shift and while the screen is locked.
• Set up and operate the app release process, including beta distribution, store consoles, signing, push notification credentials, and store submissions.
• Design offline synchronization with durable queues, safe retries, and clear handling of conflicts between device and server data.
• Develop warehouse scanning features and, as demand arises, a customer tracking app.
• Build supporting backend capabilities such as sync endpoints, conflict handling, and push triggers; also contribute to the React web product when mobile work allows.

Requirements

• A mobile app you personally shipped through review to both the Apple App Store and Google Play, with a live product that can be reviewed.
• Strong React Native and TypeScript skills.
• Practical experience with offline-first mobile patterns, including local data storage, queued writes, and synchronization conflicts.
• Working knowledge of push notifications on iOS and Android, including APNs credentials.
• Comfort contributing to backend code, ideally with Python and FastAPI or transferable experience with a comparable framework.
• Ability to work independently and carry tasks through to completion.
