Senior Mobile Engineer - Instrumentation SDK (iOS) | Spain | Remote

Requirements:

• Strong mobile engineering experience: with iOS (Swift/Obj-C) and, optionally, Android (Kotlin/Java).
• Demonstrated experience building or maintaining mobile SDKs, platform libraries, or other developer-facing platform code used by external developers.
• Experience working with performance-sensitive code (startup time, memory, network efficiency) and making pragmatic tradeoffs.
• Familiarity with OpenTelemetry (instrumentation, SDKs, collectors) or experience contributing to/maintaining OTel SDKs or similar telemetry libraries.
• Comfortable working in a fully remote, globally distributed team.

What You'll Be Doing:

• Build and evolve mobile instrumentation SDKs for iOS (Swift / Obj-C), prioritizing performance, stability, and a great developer experience.
• Design and ship SDK features such as session tracking, crash reporting, sampling strategies, automatic context propagation, and OpenTelemetry integrations.
• Own projects end-to-end.
• Break large, ambiguous problems into incremental deliverables: design modular solutions, ship MVPs, gather feedback, iterate quickly.
• Ensure quality: automated tests, CI, documentation, and smooth, backwards-compatible upgrade paths.
• Collaborate cross-functionally with backend, frontend, product, and solutions engineering to ensure cohesive end-to-end observability workflows.
• Engage with the open-source community: review PRs, discuss design proposals, and help guide external contributors.
• Mentor teammates, participate in technical design discussions and help shape the mobile observability roadmap.

Nice to Haves:

• Contributions to OpenTelemetry, crash reporting libraries, or other observability OSS.
• Experience with cross-platform frameworks (React Native, Flutter) or building native bindings/bridges.
• Experience with mobile security, privacy, or platform integration challenges.
• Prior work on crash aggregation, session replay, or sampling for mobile telemetry.
