Senior Software Engineer (iOS), SDK

📋 Description

• • Own the end-to-end evolution of Sentry’s iOS SDK, guiding architecture, feature design, and developer experience for a library that is embedded in thousands of production apps and processes more than a billion events daily.
• • Pioneer next-generation capabilities such as Session Replay, on-device AI-powered diagnostics, and real-time performance profiling, leveraging the newest Apple frameworks (Swift Concurrency, SwiftUI, Foundation Models) while maintaining backward compatibility.
• • Design and maintain public APIs that are intuitive, type-safe, and resilient at massive scale; write extensive unit, integration, and UI tests to ensure reliability across iOS versions and device families.
• • Collaborate daily with product managers, backend engineers, and the open-source community to translate customer pain points into elegant, reusable SDK features that reduce debugging time and improve app stability.
• • Act as the technical authority for iOS inside Sentry: review pull requests, mentor junior engineers, author architecture decision records, and represent the team in cross-functional planning sessions.
• • Contribute full-time to our open-source repositories, engaging with external contributors, triaging GitHub issues, and releasing regular updates that set industry standards for transparency and quality.
• • Optimize SDK footprint and runtime overhead so that monitoring never slows customer apps; benchmark against industry leaders and publish performance reports that demonstrate our commitment to speed.
• • Build tooling and CI/CD pipelines (GitHub Actions, Fastlane, Swift Package Manager) that automate testing, code signing, and distribution across multiple Xcode versions and device simulators.
• • Partner with the security team to implement privacy-safe data collection, encryption, and PII scrubbing, ensuring compliance with GDPR, CCPA, and Apple’s App Tracking Transparency.
• • Influence the long-term mobile strategy at Sentry by participating in quarterly OKR planning, presenting technical roadmaps to leadership, and evangelizing best practices at conferences and meetups.
• • Work from our Vienna hub three anchor days a week (Mon, Tue, Thu) to foster whiteboard sessions, pair programming, and rapid feedback loops, while enjoying flexible remote days for deep focus.
• • Immerse yourself in a culture that values craftsmanship: weekly engineering talks, internal hack weeks, and dedicated learning budgets keep you on the cutting edge of iOS and beyond.
