Descripción del empleo

Grafana Labs is the company behind Grafana Cloud, the fully managed observability platform trusted by more than 10,000 organizations to ensure reliability, resolve incidents faster, and optimize telemetry at scale. Built on open source and open standards and designed for interoperability across any stack, Grafana Cloud brings AI to observability and observability to AI, giving teams (and their agents) unified visibility so they can see, understand, and act on all their disparate data, wherever it lives, and move at the speed of their ambitions. Customers, including Anthropic, Bloomberg, NVIDIA, Microsoft, and Salesforce, rely on Grafana Labs. We are a 100% remote company with team members across 40+ countries, backed by leading investors including Lightspeed Venture Partners, Sequoia Capital, GIC, Coatue, J.P. Morgan, CapitalG, and Lead Edge Capital. Learn more at grafana.com and follow us on LinkedIn and X.
We’re scaling fast and staying true to what makes us different: an open-source legacy, a global collaborative culture, and a passion for meaningful work. Our team thrives in an innovation-driven environment where transparency, autonomy, and trust fuel everything we do.
You may not meet every requirement, and that’s okay. If this role excites you, we’d love you to raise your hand for what could be a truly career-defining opportunity.
This is a remote opportunity and we would be interested in applicants based in Spain, Ireland, Germany, the UK or Sweden at this time.

The Opportunity

Grafana Observability builds end-to-end observability that spans application, infrastructure, database, browser, and mobile. Our Mobile Observability initiative gives mobile developers first-class instrumentation SDKs that capture traces, metrics, logs, crashes, and user sessions. Our solutions aim to be tightly integrated with OpenTelemetry and Grafana Cloud. We’re building high-performance, low-overhead SDKs that make it easy for teams to connect mobile signals to backend and infra telemetry for true full-stack visibility.
We value open standards, great developer experience, and doing the hard engineering needed to ship reliable software at scale. You may not meet every requirement below. If this role excites you, please raise your hand.

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.

What Makes You a Great Fit

• 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: 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.
• 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.

Bonus Points For

• 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.
