We're looking for a Junior Developer to help build and ship OMS's mobile and backend applications. You'll work across the stack — building cross-platform, offline-capable mobile apps with React Native and REST APIs with Spring Boot — and be involved in the full release cycle, including publishing to the Google Play Store. This is a hands-on role with plenty of mentorship and room to grow.

Responsibilities
Develop and maintain cross-platform mobile features using React Native
Build and consume RESTful APIs using Java and Spring Boot
Build and maintain offline-first data storage and sync between the mobile app and backend using WatermelonDB, so the app stays usable without connectivity
Prepare and publish app builds to the Google Play Console — signing, versioning, and release tracks
Fix bugs, write clean code, and participate in code reviews
Collaborate with senior developers, testers, and product stakeholders
Write basic unit tests and help with debugging and troubleshooting

Requirements
Working knowledge of React Native (components, navigation, state, API calls)




Solid ReactJS knowledge
Hands-on experience with WatermelonDB for offline-first data storage and background sync
Basic understanding of Java and the Spring Boot framework
Familiarity with REST API concepts (JSON, HTTP methods, status codes)
Understanding of the Google Play Store publishing process, or eagerness to learn it
Version control experience with Git
Willingness to learn and take feedback
NodeJS or another server-side JS framework is a plus
Experience with iOS App Store submission is a plus
Exposure to databases such as MongoDB, MySQL, or PostgreSQL is a plus
Familiarity with CI/CD pipelines is a plus
Basic knowledge of Android build tooling (Gradle, keystores) is a plus
Understanding of authentication (JWT / OAuth) is a plus
