About the role
This is a hands-on, high-ownership senior role focused on building, maintaining, and architecting Appier's unified mobile growth stack. You will bridge engagement technologies with monetization and measurement solutions, ensuring high performance, cross-platform consistency, and privacy-first standards while driving AI-assisted engineering innovations.
Responsibilities
- Architect Cross-Platform SDKs: Design features and developer-friendly APIs that behave identically across iOS, Android, React Native, Flutter, and Web, including hybrid JS-to-native bridges where needed.
- Feature Development & Privacy: Build high-value features for engagement (real-time tracking, push notifications, AI recommendations) and monetization/measurement, while ensuring strict support for evolving platform privacy requirements.
- Quality & Reliability: Lead root-cause investigations for complex client issues, maintain strict SLOs/crash-free rates, and manage CI/CD, automated testing, semantic versioning, and backward compatibility.
- AI-First Engineering & Leadership: Utilize AI coding agents daily to optimize design and code reviews, mentor engineers, and elevate team standards.
About You
[Minimum qualifications]
- 5+ years of software engineering experience, with 3+ years specifically building mobile SDKs or libraries for external/enterprise clients.
- Expert-level Swift (modern Swift Concurrency, async/await, actors) and/or Kotlin (Coroutines & Flow).
- Solid understanding of iOS/Android architecture, app lifecycles, background execution, and push notification systems (APNs, FCM).
- Deep expertise in mobile performance optimization (memory, battery, network efficiency) and implementing platform privacy requirements (e.g., Apple Privacy Manifests, Android Privacy Sandbox).
- Proficiency with CI/CD, automated testing, Git, and SDK versioning.
- Comfort using AI coding agents (e.g., Claude Code, Cursor, Copilot) as part of your daily workflow.
[Preferred qualifications]
