JOB DESCRIPTION:
Android Engineer (Test and Development)
ABOUT LINGO
Lingo is building a cutting‑edge digital health platform that fuses continuous biosensor data, high‑performance backend engineering, and advanced analytics to help people live healthier, longer, fuller lives. Our systems process massive volumes of real‑time data, and the backend is the heartbeat of the platform.
THE OPPORTUNITY
Join as an Android engineer who will begin by building and maintaining native test automation for our Android app to enable fast, safe releases in a regulated environment (HIPAA/GDPR). As the automation foundation stabilizes, you’ll transition into feature development in Kotlin contributing directly to the product experience. This role is hands-on engineering, not a test-only position.
WHAT YOU’LL DO
- Native test automation (initial focus): Build and maintain UI and integration tests using Espresso and Jetpack Compose Testing (ComposeTestRule), , BDD with Cucumber (Xray integration), plus JUnit and MockK.
- Evolve testing foundations: Define along with other developers, conventions, utilities, fixtures, and deterministic data for reliable, maintainable tests, reducing flakiness and speed up feedback.
- Wire test suites into Gradle/GitHub Actions (or similar) with sharding/parallelization; operate runs on device farms (eg.: Firebase Test Lab)
- Observability-assisted debugging: Use logs, crash reporting, and network inspection tools to triage issues quickly and validate fixes with developers.
- Feature development (growing focus over time): Build Android features in Kotlin using modern patterns (eg.: Jetpack Compose, MVVM, Coroutines/Flow, DI with Hilt/Dagger), write clean, testable code.
- Collaboration and quality: Partner with Product/Design for UX fidelity, participate in code reviews, and contribute to maintainable architecture and coding standards.
- Compliance support: Produce traceable, auditable test artifacts and follow privacy-by-design practices appropriate for regulated products.
REQUIRED QUALIFICATIONS
- 4 years of experience in Android Development with Kotlin
- Hands-on experience with Android test frameworks: Espresso, Jetpack Compose Testing, JUnit; mocking with MockK (or Mockito).
- CI/CD experience for Android (Gradle, test sharding/parallelization) and running tests on cloud device farms.
- Strong debugging skills using logs, crash reports, and network inspection; able to isolate issues across app layers and environments.
- Strong communication skills in English.
PREFERRED QUALIFICATIONS
- Experience building features with Jetpack Compose, MVVM, Coroutines/Flow, and DI (Hilt/Dagger).
- Background in digital health or other regulated, data-intensive products, familiarity with privacy-by-design.
- Accessibility, localization, and performance optimization experience on Android.
LINGO CULTURE
Customer-first, quality-driven, growth-minded, and united. You’ll enable fast, safe releases by embedding quality into every stage of delivery and making it visible and measurable.
