We are looking for a highly capable Senior iOS Engineer to join our Powered team and take ownership of our iOS 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 iOS devices. In our classic SDKs, much of this measurement logic lives in a shared C++ library used across Android, iOS, and embedded target, so you'll have an opportunity to work across the Swift, Objective-C and C++ boundary.

In our new SDKs, most of this logic lives in a Kotlin Multiplatform project, so you'll have the opportunity to work with the emerging technologies that power our operations. You have experience with the iOS 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. Design, implement, and maintain network measurement features in the CQoE and Speedtest iOS SDKs, consumed by external carrier partners, third-party app developers, and internal client apps. This includes implementation, testing, documentation, deployment, and development support Design, implement, and maintain network measurement features in our new Speedtest iOS SDKs, consumed by enterprise customers.

This includes implementation, testing, documentation, deployment,



and development support Work on the shared C++ measurement engine used across Android, iOS, and embedded targets by debugging native code and, over time, contributing to and maintaining it directly Bring AI-assisted tooling into coding, QA, and data analysis where it genuinely earns its place, with clear guardrails around safety, privacy, security, and verification Stay hands-on where it counts (technical reviews, architecture discussions, targeted implementation) while taking ownership of delivery end-to-end on the features and fixes you drive Roll out SDK and measurement changes deliberately: gate them behind feature flags, run quality checks, and verify post-release that real-world behavior matches intent before widening exposure 5+ years of software development experience, with a solid foundation in data structures, algorithms, and design patterns ~ Experience with iOS using Swift ~ Strong data literacy: comfortable writing SQL to investigate production and measurement data, using Python (or similar) for analysis, and applying data-quality monitoring practices to catch anomalies before they reach partners ~ Excellent debugging, troubleshooting, data analysis skills ~ Experience with telecom/network measurement, QoE/QoS systems,



or RF/cellular domain knowledge Experience with Android, Java, Kotlin Experience with Kotlin Multiplatform.

Experience with embedded systems using C++ Strong understanding of networking fundamentals (IP, TCP/UDP, WebSocket).
