Senior Mobile Infrastructure Engineer, Ambient AI

About the role

We’re building a next-generation ambient AI platform for healthcare, helping clinicians focus on patient care by automatically capturing, understanding, and structuring clinical conversations in real time. Mobile is at the center of this experience. Our apps power long-form audio recording, real-time streaming, offline reliability, background sync, and AI-assisted clinical workflows in environments where reliability is mission-critical.

Responsibilities

• Own and evolve our primarily Flutter-based mobile platform, including native Swift/iOS and Kotlin/Android integrations for audio capture, background execution, permissions, performance, and platform-specific constraints.
• Core areas include: Real-time audio capture, streaming, chunked uploads, and long-form clinical recording; Offline-first data handling, local persistence, background sync, and recovery flows; App performance across startup time, responsiveness, memory, battery usage, and background execution; Mobile observability, crash reporting, error handling, logging, and regression detection; Release infrastructure, CI/CD automation, build systems, signing, and App Store / Play Store workflows.
• Build and improve foundational mobile frameworks used across our apps, such as: Audio recording and processing abstractions; Caching and persistence layers; State management patterns; Navigation and component systems; Networking, retry, and sync primitives; Mobile observability and diagnostics tooling;
• Strengthen mobile reliability by systemically reducing crashes, improving release readiness, and preventing regressions before they reach clinicians.
• Partner with product, backend, AI, and design teams to understand emerging infrastructure needs and unblock fast, reliable product development.
• Contribute occasionally to adjacent surfaces such as our Chrome extension and web app, primarily where mobile, audio, AI workflow, or platform infrastructure needs intersect.
• Mentor other engineers and help raise the technical bar across mobile.

Requirements

Professional mobile development experience, with deep experience in iOS, Android, or both.

Strong native mobile expertise in Swift/iOS and/or Kotlin/Android, including app lifecycle, background execution, permissions, performance, and platform-specific constraints.

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.

Experience building or maintaining production-grade mobile infrastructure at scale.

Experience working in cross-platform mobile environments, such as Flutter, React Native, Kotlin Multiplatform, shared native modules, or similar architectures.

Strong understanding of mobile architecture, release processes, CI/CD, testing, observability, and reliability best practices.

Experience improving app performance, crash rates, release quality, or developer velocity through platform-level investments.

Comfort working across product, backend, design, and AI engineering teams in a fast-moving environment.

Ownership mindset and strong bias for action — you’ve owned meaningful parts of a mobile stack and driven ambiguous infrastructure work to completion.

Qualifications

Experience with audio/video streaming, real-time media pipelines, audio chunking, transcription, or background recording.

Experience with offline-first systems, sync engines, conflict handling, or resilient local persistence.

Experience with mobile observability tools such as Firebase Crashlytics, Sentry, Datadog, Amplitude, or similar.

Experience with Fastlane, Firebase App Distribution, TestFlight, Play Console automation, build optimization, or release automation.

Experience with AI-native product experiences, real-time transcription, multimodal workflows, or agentic user experiences.

Exposure to healthcare, HIPAA, SOC 2, security, encryption, privacy, or regulated mobile environments.

Flutter/Dart experience, including Riverpod or similar state management patterns.

Experience with Shorebird, CodePush, or other mobile over-the-air update platforms.

Light JavaScript, TypeScript, Chrome extension, or web app experience.
