## Description

Insight Global is seeking a Senior Mobile Software Developer to help build, maintain, and ultimately bring full ownership of mobile applications in-house. These apps serve millions of users worldwide.

This role will work closely with the existing senior developer and an external development partner. The selected candidate will be embedded into active mobile projects immediately and play a key role in the transition of the mobile app from a contracted model to a fully internalized, single-source architecture later this year.

The ideal candidate loves mobile development, is comfortable owning production systems end-to-end, and enjoys fixing, improving, and extending systems-not just maintaining them.

What You'll Do

Develop and maintain iOS and Android mobile applications using React Native and Expo

Collaborate closely with an external mobile development partner through the remainder of the contract term, then help transition all mobile development fully in-house

Build and extend features within an active product roadmap, including UI updates and new mobile capabilities

Implement platform-specific native modules in Swift (iOS) and Kotlin (Android) when needed

Help guide the transition to a single-source mobile architecture, integrating with a Python-based backend

Architect and optimize mobile data-fetching layers using REST and GraphQL APIs

Own app lifecycle responsibilities including CI/CD pipelines, build configurations, and App Store / Google Play releases

Diagnose and improve performance across startup time, memory usage, battery efficiency, and rendering

Participate in planning, requirements gathering, technical design, solution research, and documentation

Conduct code reviews and maintain strong source control and secure coding standards

Provide technical guidance and best practices to leadership and cross-functional teams

Proactively identify issues, fix bugs independently, and continuously improve the mobile app codebase
