Mobile Developer (React Native)

We’re looking for a mobile developer with at least 4 years of experience in React Native and JavaScript/TypeScript to help us take our mobile applications further by building new features, improving performance, and maintaining existing codebases across our healthcare products.

Your main focus will be working on two core mobile applications we run in the healthcare industry: one for doctors and one for patients. These apps are already in production and actively used, so the work involves both feature development and long-term technical improvements.
Some work may also involve platform-specific integrations or features that require bridging to native iOS (Swift) or Android (Kotlin) code. Where needed, you will have the space to learn and collaborate on areas outside your comfort zone.
You will start with smaller tasks to help you understand the scope of the application. As you become more familiar with the system, you will take on more complex work, including performance tuning and refactoring.
You will be part of a fully remote team that works through text-based communication tools such as backlogs, wikis, and Slack. Strong asynchronous communication is essential for this position. You should be able to explain your thinking clearly and collaborate effectively with the team.
Some of the technologies and tools we use include: React Native, TypeScript, Stripe, Twilio, S3, Sentry, GraphQL, Swift, and Kotlin.

Developers have different strengths in different areas. Here are some of the categories we would assess candidates based on. Strength in one area can offset weakness in another.

• Strong experience with React Native and JavaScript/TypeScript
• Experience working in production environments
• Solid understanding of how mobile apps behave across different states, including navigation flows, background/foreground transitions, and state persistence.
• Familiarity with Apollo, React Query, or similar data libraries
• Familiarity with native development using Swift or Kotlin
• Experience with camera functionality, file uploads, or native bridging is a plus (AVFoundation, CoreImage)
• Experience with Twilio, S3, or analytics tools such as Sentry is a plus
• Experience with healthcare-related development or integrations is a plus

This is a full-time remote position. We’re used to working as a dispersed team, so you must be cool with collaborating online and a lot over text. We’re flexible on schedules, but at least 4 hours of overlap with a core of your team is mandatory.
