• Knowledge of push notifications, background app tasks, and managing network connections for real-time updates.
• Familiarity with modern iOS tools like Xcode, Instruments, and the debugging process.
• Strong understanding of user experience (UX) principles, with the ability to design elegant, simple solutions for complex problems.
• Experience with automated testing frameworks (Unit, UI, Integration testing) and CI/CD pipelines.

The salary range for this position is $113,400 - $162,000 per year, depending on location and experience. In addition to your base salary, we offer a company performance bonus and equity.
