• Test on real devices, including Apple Watch.

• Work with backend developers on API integration.

Required

• At least 3 years of professional iOS development.

• Strong Swift and Xcode.

• Hands-on HealthKit: observer queries, background delivery and anchored queries.

• Experience writing native modules for a cross-platform framework (Capacitor, React Native or similar).

• REST APIs, JSON, Git, and secure storage (Keychain).

• Able to work independently and remotely.

Nice to have

• SwiftUI or UIKit.

• Experience with GDPR or other health-data privacy requirements.

• Apps you have shipped that read HealthKit.
