Mobile Engineer: Instrumentation SDK

Build and evolve mobile instrumentation SDKs for iOS (Swift / Obj-C) and Android (Kotlin / Java), 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. We invest heavily in developer productivity. You can use modern AI coding assistants as part of your daily workflow (your choice of tools, within security guidelines), backed by a company-funded usage budget so you can iterate quickly without unnecessary friction. We encourage pragmatic AI-assisted development: faster prototyping, test generation, refactors, documentation, and incident follow-ups-always paired with strong code review and quality standards. You'll also have access to frontier models (e.g., GPT-Codex 5/3, Claude Opus 4.6, Gemini 3 Pro).

You're a motivated self-starter with a bias toward action and the ability to run with poorly defined scopes. You can operate autonomously while being highly collaborative. Strong mobile engineering experience (one or both): iOS (Swift/Obj-C) and/or 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. Excellent written and verbal communication Comfortable working in a fully remote, globally distributed team. Coachable, customer-focused, and passionate about developer experience, you can do more than code: you write docs, mentor others, and shape roadmaps. Pragmatic and comfortable navigating ambiguity: you prioritize progress over perfection and iterate quickly based on feedback.

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.
