Senior Software Engineer (Mobile SDK, Android)

The Opportunity: We are looking for a highly capable Senior Android Engineer to join our Powered team and take ownership of our Android SDKs: the CQoE SDK, which telecom carriers and partners embed directly into their own apps to passively measure real-world network quality, and the Speedtest SDK, the core measurement library that powers every Speedtest client. You will be responsible for implementing and maintaining features that perform a wide variety of network measurements on millions of Android devices. Much of this measurement logic lives in a shared C++ engine used across Android, iOS, and embedded targets, so you’ll have an opportunity to work across the Kotlin/Java, JNI/NDK, C++ boundary. You love to code and appreciate well-designed APIs, as you will need to strike the right balance between SDK and application code. You have experience with Android platform, but are interested in both Android and iOS as well as embedded environments. You want to make a better Internet for everyone. If you already use Ookla ’s tools to check your broadband or mobile data performance, now you have a chance to be a part of the team that produces them. Key Responsibilities: Design, implement, and maintain network measurement features in the CQoE and Speedtest Android SDKs, consumed by external carrier partners, third-party app developers, and internal client apps. This includes implementation, testing, documentation, deployment, and development support Work across the JNI/NDK boundary i
