Android Developer – Network Measurement App

Product Development
Remote - United Kingdom

Ookla is a global leader in connectivity intelligence, offering unparalleled network insights through the combined expertise of Speedtest, Downdetector, RootMetrics, and Ekahau. Ookla’s complementary datasets combine crowdsourced and controlled, public and private collection methods, QoS and QoE metrics, and more to unlock correlations and actionable insights — helping organizations optimize networks, enhance digital experiences, and create better connected experiences for end-users.

Our team is a group of people brought together through passion and inspired by possibility. We are looking for team members who love solving problems, are motivated by challenges, and enjoy turning clever ideas into exceptional products. When you work for us, you are using Ookla data and insights to advance our mission of better connectivity for all.

Role Summary

We're looking for a skilled Android Developer to join our team to work on a mobile application and SDK that performs mobile/cellular network measurements in the background and provides a wide range of services allowing users to obtain information on how the network is performing in their area (including the display of coverage data on a map). The app is built using both Kotlin and Java so proficiency in both is essential. While your primary focus will be on Android development, experience in iOS development and backend development using Django (Python) would be a significant advantage.

Responsibilities

1. Develop and maintain an Android application using Kotlin and Java.
2. Implement background testing services for network measurement while optimising performance and battery consumption.
3. Integrate and display real-time data on interactive maps (i.e. Google Maps, HERE Maps).
4. Ensure smooth and secure network communication using REST APIs, WebSockets, or other relevant protocols.
5. Collaborate with designers, backend developers, and data scientists to improve app features.
6. Debug and optimise app performance, ensuring reliability and information security.
7. Stay updated with the latest Android development trends and best practices.

Preferred Qualifications

1. 3+ years of experience in Android development using Kotlin and Java.
2. Strong understanding of Android background processing, WorkManager, and battery optimisation.
3. Experience with Google Maps API, Here Maps and other mapping libraries.
4. Familiarity with network communication protocols, HTTP clients and WebSockets.
5. Good knowledge of iOS development (Swift) and React Native to assist with cross-platform considerations.
6. Experience with Django, PostgreSQL and Python for backend development, including REST API design.
7. Good working knowledge of UI and unit testing on Android and Python.
8. Familiarity with SQLite for local data storage and Firebase.
9. Good understanding of MVVM architecture.
10. Experience with CI/CD pipelines and automated testing.
