About The Position

WHOOP is hiring a Staff Android Engineer for its Connectivity team to own the architecture and technical direction of the software that connects WHOOP hardware to the Android app. The team bridges embedded and mobile engineering to provide WHOOP members with a seamless, reliable experience. This role spans the Android connectivity layer, from BLE transport through history synchronization and firmware delivery, and focuses on scaling connection performance and availability across Android devices. At Staff level, the role’s impact includes influencing engineers and technical decisions beyond the immediate team. The engineer will work with hardware, firmware, software, and backend teams; establish and refine strap-to-Android communication protocols aligned with iOS standards; and use connectivity telemetry and user feedback to guide improvements. The position also involves mentoring and onboarding mobile engineers, supporting incident response and app releases, and representing Android Connectivity in cross-functional forums. The role is based in WHOOP’s Boston, Massachusetts office. The successful candidate must be prepared to relocate if necessary. The position is full-time, with a stated U.S. base salary range of $170,000–$230,000, plus benefits and equity.

Experience working with consumer-facing apps that control BLE devices.
Track record of influencing engineers beyond one's own team in applying architectural and platform design principles.
Expert knowledge of concurrency and multithreading best practices, including Kotlin coroutines and Flow.
Product-minded approach and empathy for the member experience.
Willingness to learn and grow rapidly across Android and external systems.
Extensive professional experience building, testing, debugging, and delivering native Android apps.
Expert knowledge of Android application structure and components, lifecycle, and Android Design Guidelines.
Strong experience with Jetpack Compose and modern declarative Android UI.
Experience with Kotlin and frameworks such as Koin, Android Jetpack libraries including ViewModel, Flows, and Navigation, Room, and Retrofit or OkHttp.
Experience designing modular architecture and dependency boundaries in a large multi-module Gradle codebase, including patterns such as MVI and MVVM.
Excellent knowledge of Android Studio, Gradle, and CI systems.
Experience debugging and diagnosing issues across complex or distributed systems involving firmware, mobile, and backend.
