Role Overview:

We're seeking a Senior Mobile Engineer whose primary ownership is our React Native customer app (iOS + Android), and who can also contribute to our Next.js web applications.

- Implement and maintain push notifications, deep linking, in-app payments, telehealth video flows, and subscription management
- Ensure the app meets HIPAA/PHI requirements — keep PHI out of logs, crash reports, and third-party SDKs; vet SDKs for BAA suitability
- Keep the app current with OS/store requirements (e.g., target the latest required Android API level) and diagnose device-specific iOS/Android issues; profile and optimize performance
- Participate in code reviews and contribute to mobile architecture decisions

Secondary Responsibilities — Web (~20%)

- Able to read and contribute to a React/Next.js web codebase
- Experience consuming RESTful APIs and handling asynchronous data
- Git; strong problem-solving; attention to detail
- Proficient in English; able to work independently in a remote environment across time zones

Nice-to-Have
