• Help with automated testing, continuous integration, code reviews and technical documentation.
• Work with engineers in other countries to ship scalable, dependable software.

Requirements

• 4+ years of professional software development, with strong mobile engineering experience.
• Advanced skill in Android (Java) or iOS (Objective-C), and willingness to learn the other platform.
• Good grasp of mobile architecture, application lifecycles, APIs, performance tuning and debugging.
• Experience building, integrating or maintaining mobile SDKs, libraries or frameworks is highly desirable.
• Knowledge of Kotlin, Swift, C/C++, JNI or Android NDK is an advantage.
• Hands-on work with automated testing, CI/CD, Git, multithreading and networking basics.
• Strong analysis, problem solving and communication, and comfort working in international Agile teams.
