• 4+ years of professional software development experience, including strong mobile engineering expertise.
• Advanced development skills in either Android (Java) or iOS (Objective-C), with a willingness to learn and contribute to the other platform.
• Solid understanding of mobile architecture, application lifecycles, APIs, performance optimization, and debugging.
• Experience developing, integrating, or maintaining mobile SDKs, libraries, or frameworks is highly desirable.
• Familiarity with Kotlin, Swift, C/C++, JNI, or Android NDK is an advantage.
• Experience with automated testing, CI/CD, Git, multithreading, and networking fundamentals.
• Strong analytical, problem-solving, and communication skills, with the ability to collaborate in international Agile teams.
