Role overview

WHOOP is seeking a Staff Android Engineer for its Connectivity team to own the architecture of the software layer connecting WHOOP hardware to the Android app. At the staff level, your influence will extend beyond code to shaping technical decisions and guiding other engineers across the organization.

Key responsibilities

Own the complete architecture of the Android connectivity layer, including Bluetooth Low Energy transport, history synchronization, and firmware delivery across a large modular codebase.
Establish and maintain communication protocols between the WHOOP strap and Android devices while ensuring consistency with iOS standards.
Apply expert knowledge of the Android Bluetooth stack to manage GATT operations, device bonding, and reconnection logic across real-world scenarios.
Diagnose and resolve connectivity issues across the fragmented Android device landscape by addressing original equipment manufacturer-specific Bluetooth, power management, and permission behaviors.
Create systems to analyze connectivity health across the member base and use this telemetry to inform team priorities.
Mentor engineers across the Android organization, facilitate developer ramp-up, and elevate engineering quality through code reviews, test coverage expansion, and architectural refinement.
Participate in incident commander rotation for the WHOOP ecosystem and manage the full release process including app builds, signing, testing through Firebase, and Play Store submission.

Requirements

Demonstrated experience building consumer-facing applications that control Bluetooth Low Energy devices.
Proven track record of influencing engineers beyond your immediate team through architectural and platform design expertise.
Expert proficiency in Kotlin, including advanced knowledge of coroutines and Flow for concurrent and multithreaded operations.
Extensive professional experience building, testing, debugging, and delivering native Android applications with deep knowledge of application structure, components, lifecycle, and Android Design Guidelines.
Strong experience with modern Android development tools and frameworks including Jetpack Compose, Jetpack libraries, Room database, Retrofit, OkHttp, and dependency injection frameworks like Koin.
Demonstrated ability to design modular architecture across large multi-module Gradle codebases using patterns such as MVI and MVVM, along with expertise in Git, Android Studio, Gradle, and CI systems.
Strong experience debugging complex distributed systems and communicating with RESTful backends, with a firm commitment to automated testing and experience writing both unit and UI tests.

What makes this role worth considering

This position is based in WHOOP’s Boston, MA office where you’ll work within a cross-functional environment collaborating directly with hardware, firmware, and software teams. Your work will directly impact performance and reliability for a global member base using the latest cutting-edge connectivity technology at scale.
