Senior Mobile Infrastructure Engineer, Ambient AI

Athelas

Mountain View, CA • On-site

Full-time

Re-posted 28 days ago


Job description

Job Summary:
Athelas is focused on building the AI Operating System for healthcare, aiming to transform the administrative burdens of the industry. They are seeking a Senior Mobile Infrastructure Engineer to develop their next-generation ambient AI platform, enhancing mobile applications that improve clinician workflows and patient care through advanced technology.
Responsibilities:
• Own and evolve our primarily Flutter-based mobile platform, including native Swift/iOS and Kotlin/Android integrations for audio capture, background execution, offline reliability, performance, and observability. Core areas include:
• Build and improve foundational mobile frameworks used across our apps, such as:
• 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.
• Help shape the technical direction for mobile architecture as we scale the Ambient AI product line.
• 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. There is an opportunity to grow into broader mobile technical leadership or people leadership over time, but management is not required for this role.
Qualifications:
Required:
• 5+ years of professional mobile development experience.
• 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.
• 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.
Preferred:
• 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.
Company:
Athelas develops technology to monitor chronically ill patients in their homes. It is a sub-organization of Commure. Founded in 2016, the company is headquartered in Mountain View, USA, with a team of 201-500 employees. The company is currently Growth Stage.
