Senior iOS SDK Engineer - Network QoE & Speedtest

Ziff Davis, LLC; Málaga; Híbrido; EUR 50.000 - 64.000; Jornada completa

Descripción de la vacante

Ookla, an Accenture company, seeks a Senior iOS Engineer to own the iOS SDKs (CQoE and Speedtest) used by carriers and partners. You will design, implement, and maintain features that measure network performance across iOS, Swift, C++, and Kotlin Multiplatform, with AI-assisted tooling and cross‑platform collaboration.

You will work on the shared measurement engine across Android, iOS, and embedded targets, debugging native code and contributing to its evolution, while delivering end-to-end

Formación

• 5+ years of software development experience.
• Experience with iOS using Swift.
• Substantial experience building and maintaining SDKs or libraries.
• Strong data literacy: SQL to investigate production and measurement data, Python for analysis, and data-quality monitoring practices.
• A curious, proactive stance toward AI and modern engineering practices.
• Excellent debugging, troubleshooting, data analysis skills.
• Strong time management skills and a self-driven work ethic.

Responsabilidades

• 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.
• Design, implement, and maintain network measurement features in our new Speedtest iOS SDKs, consumed by enterprise customers.
• 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.
