Senior Software Engineer (Mobile SDK, Android)

Stack

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, including testing, documentation, deployment and development support.
• ▹Work across the JNI/NDK boundary into the shared C++ measurement engine 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.

Requirements

• ▹5+ years of software development experience, with a solid foundation in data structures, algorithms and design patterns.
• ▹Experience with Android using Kotlin and Java.
• ▹Substantial experience building and maintaining SDKs or libraries.
• ▹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.
• ▹A curious, proactive stance toward AI and modern engineering practices.
• ▹Excellent debugging, troubleshooting and data analysis skills.
• ▹Strong time management skills and a self-driven work ethic.

Nice to have

• ▹Experience with telecom/network measurement, QoE/QoS systems, or RF/cellular domain knowledge.
• ▹Experience with iOS.
• ▹Strong understanding of networking fundamentals (IP, TCP/UDP, HTTP/S, WebSocket).
• ▹Experience with embedded systems using C++.
