Mobile Application Engineer

Description

The company is transforming the quality and accessibility of healthcare by automating clinicians’ most time-consuming tasks.

Thousands of clinicians across multiple disciplines use Lyrebird every day in environments where accuracy, safety, and time matter deeply. Everything we build is grounded in earning trust, reducing cognitive load, and delivering meaningful impact at scale.

Responsibilities

• Lyrebird’s product lives or dies in a single moment: a clinician starting a consultation and trusting that every word is being captured. Today, that moment happens in the browser. As our first Mobile Application Engineer, you’ll take ownership of bringing Lyrebird to iOS and Android, starting with the capability that matters most: reliable audio capture on a phone. You’ll own the mobile application end to end, from the build pipeline and store releases to bringing our core web features into a native experience that works in the real conditions clinicians face every day.
• This role suits someone who enjoys being the person who owns the whole thing. You’re comfortable moving between native platform APIs and a TypeScript codebase, you care about the unglamorous details (permissions, interruptions, flaky networks), and you get satisfaction from shipping something that simply works when it matters. You’ll enjoy the autonomy of shaping a platform from its early days, and the responsibility of building for people who can’t afford for their tools to fail mid-consultation.
• Implement and own the mobile build pipeline, producing signed iOS and Android builds and keeping configuration current
• Release the app to the App Store and Google Play, managing versioning, phased rollouts, and store review
• Deliver mobile audio capture for consultations, handling microphone permissions, background recording, and interruptions such as incoming phone calls
• Make audio uploads resilient on poor networks, with retry and resume built in
• Bring mature web features into the mobile app, matching their behaviour and resilience whilst adapting the experience for small screens
• Optimise reporting and telemetry, then use what you learn to make the app more stable
• Build and maintain the mobile test suite and run it as part of the build pipeline
• Keep across platform changes from Apple and Google and plan the work they require
• What you’ll bring
• Strong experience in cross-platform development (React Native). Preferable to also have experience in Swift/SwiftUI and Kotlin.
• Hands-on experience with mobile audio capture, including background audio, interruption handling, and microphone permissions (for example AVAudioSession, AudioRecord, or MediaRecorder in a WebView)
• Experience automating mobile builds and releases with tools such as Expo (EAS), Xcode Cloud, or Gradle, including code signing and phased rollouts on both stores
• Confidence in TypeScript and the ability to read and change a SvelteKit web codebase
• Experience with mobile test automation using Browserstack.
• Experience integrating mobile apps with REST APIs

Requirements

• Experience with Progressive Web Apps, including service workers, web app manifests, and offline caching
• Experience setting up mobile crash reporting and telemetry with Sentry or similar
• A working knowledge of on-device data protection, such as encryption at rest and short data retention
• Familiarity with Sveltkit and Typescript backend frameworks
• Familiarity with AWS and Terraform
• Experience building software for healthcare or other regulated environments
• Every minute a clinician spends on admin is a minute taken away from a patient. Putting Lyrebird in a clinician’s pocket means it can be there on a ward round, in a community visit, or anywhere care actually happens. You’ll be building the foundation that makes that possible, and your work will be felt directly by clinicians and the patients in front of them.
• We’re building a team that reflects the diversity of the people who benefit from our work. We want Lyrebird to be a place where everyone feels safe, supported, and able to thrive. If you’re from an underrepresented background in tech, we strongly encourage you to apply, even if you don’t meet every requirement.
