- Leading delivery of onboarding flows, AI insights feeds, media capture pipelines and personalised push notifications.

Engineering Leadership

- Establishing CI/CD workflows, automated builds and test pipelines for App Store and Google Play releases.
- Maintaining high code quality through code reviews, automated unit and E2E testing, and continuous monitoring.
- Partnering with leadership to estimate complexity, set milestones and scale the engineering team.

Requirements – What we're looking for:

- 5+ years of professional mobile app development experience.
- A track record of launching and scaling consumer-facing (B2C) apps.
- Deep proficiency in React Native or Flutter, or native Swift / Kotlin.




- Experience integrating cloud AI services, real-time data feeds or on-device ML runtimes such as Core ML or TensorFlow Lite.
- Experience with device camera integrations, video/audio processing, background location services or hardware permissions.
- Strong familiarity with App Store Connect and Google Play Console release management, guidelines and compliance.
- Strong command of Git and CI/CD tools such as Fastlane, Bitrise or GitHub Actions.
- Experience with mobile analytics and monitoring tools such as Firebase and Sentry.

Valuable Experience – Nice to Have:

- A background or interest in pet tech, IoT, health and fitness, or consumer hardware.
- Experience with real-time video/audio streaming protocols such as WebRTC.
