Must-have experience
- Strong React Native experience (Expo bare workflow preferred)
- Solid JavaScript
- Experience with Legend State
- Experience with Jest (unit testing)
- Familiarity with MUI
- Comfortable working in VS Code
- Experience troubleshooting cross-platform rendering differences (Android vsiOS)

We have an existing Expo bare workflow codebase built with an offline-firstarchitecture. Our initial releases have been Android-only (company-manageddevices), and we are now expanding to support BYOD, which requires a stable iOSrelease. We already have an iOS build, but some screens do not render correctly on iOS.
A key part of this role will be
- Identifying and fixing UI/UX rendering discrepancies on iOS
- Ensuring styling and layout balance between Android and iOS
- Improving platform-specific behavior where needed

Android knowledge
- Helpful but not critical
- We have very limited custom Kotlin code (primarily for MAM integration)
- Most of our development remains in React Native

iOS / Swift knowledge
- More important than Android expertise




- We will need custom Swift development for MAM integration
- Ability to debug in Xcode
- Comfortable reviewing logs and troubleshooting native-layer issues

This is not a fully native mobile role, but the candidate should be comfortablenavigating native layers when necessary.
Our backend is
- C# .NET
- Entity Framework

We split work between frontend and backend developers. We are open to full-stackdevelopers, but the primary need is frontend/mobile. Backend changes may berequired occasionally, but deep backend specialization is not the main focus.
Nature of Work
This will be a mix of fixes and new development, including:
- Addressing 1.0 pilot issues
- Stabilizing and polishing the iOS version
- Supporting BYOD rollout
- Building a second mobile app (kiosk mode for warehouse workers)
- Adding new features to the current mobile application

Tools & Debugging
Day-to-day:
- VS Code
- For advanced debugging and log revi
