Senior Mobile Infrastructure Engineer (Ambient AI)

Join our team as a Senior Mobile Infrastructure Engineer and help us build a next-generation ambient AI platform for healthcare. You will own and evolve our primarily Flutter-based mobile platform, focusing on areas such as real-time audio capture, offline-first data handling, app performance, mobile observability, and release infrastructure. You will also partner with product, backend, AI, and design teams to understand emerging infrastructure needs and unblock fast, reliable product development. This role is ideal for someone with strong iOS and/or Android depth, cross-platform experience, and platform instincts.

• Evoluer et améliorer la plateforme mobile principalement basée sur Flutter, y compris les intégrations natives Swift/iOS et Kotlin/Android pour la capture audio, l'exécution en arrière-plan, la fiabilité hors ligne, la performance et l'observabilité.
• Renforcer la fiabilité mobile en réduisant systématiquement les pannes, en améliorant la préparation des versions et en empêchant les régressions avant qu'elles n'atteignent les cliniciens.
• Collaborer avec les équipes produit, backend, IA et design pour comprendre les besoins émergents en matière d'infrastructure et débloquer le développement rapide et fiable des produits.
• Strong understanding of mobile architecture, release processes, CI/CD, testing, observability, and reliability best practices
• Experience building or maintaining production-grade mobile infrastructure at scale
• Comfort working across product, backend, design, and AI engineering teams in a fast-moving environment
• Experience working in, or a strong willingness to ramp into, a Flutter-based mobile codebase. We value deep native iOS and/or Android expertise, and Flutter experience is a plus rather than a hard requirement
• Professional mobile development experience, with deep experience in iOS, Android, or both
• Experience working in cross-platform mobile environments, such as Flutter, React Native, Kotlin Multiplatform, shared native modules, or similar architectures
• Strong native mobile expertise in Swift/iOS and/or Kotlin/Android, including app lifecycle, background execution, permissions, performance, and platform-specific constraints
• Experience improving app performance, crash rates, release quality, or developer velocity through platform-level investments
• Ownership mindset and strong bias for action — you’ve owned meaningful parts of a mobile stack and driven ambiguous infrastructure work to completion
• Experience with offline-first systems, sync engines, conflict handling, or resilient local persistence
• Experience with audio/video streaming, real-time media pipelines, audio chunking, transcription, or background recording
• Experience with Fastlane, Firebase App Distribution, TestFlight, Play Console automation, build optimization, or release automation
• Experience with mobile observability tools such as Firebase Crashlytics, Sentry, Datadog, Amplitude, or similar
• Experience with AI-native product experiences, real-time transcription, multimodal workflows, or agentic user experiences
• Flutter/Dart experience, including Riverpod or similar state management patterns
• Exposure to healthcare, HIPAA, SOC 2, security, encryption, privacy, or regulated mobile environments
• Experience with Shorebird, CodePush, or other mobile over-the-air update platforms
• Light JavaScript, TypeScript, Chrome extension, or web app experience
