Binance is seeking a Senior Android Engineer (C++) to design and implement cross-platform mobile features for both Android and iOS using modern C++. You will work on multiple high-impact initiatives:
• Design and implement new features for an in-house mobile browser kernel based on Chromium, with focus on Android and iOS platforms.
• Design and implement features for an in-house mobile game engine based on OpenGL ES and native graphics technologies.
• Explore and integrate AI capabilities into mobile applications, including on-device AI inference, LLMs, intelligent agents, and AI-powered user experiences.
• Design and optimize AI-related components for mobile and edge devices, focusing on inference latency, memory usage, CPU/GPU utilization, power efficiency, and user experience.
• Collaborate with cross-functional teams to define, design, and deliver features across Android, iOS, and shared C++ infrastructure.
• Integrate and utilize third-party data sources, AI services, SDKs, and APIs.
• Write and execute unit tests to ensure code robustness, including edge cases and reliability.
• Troubleshoot issues, fix bugs, and continuously improve application performance, stability, and responsiveness.
• Balance responsiveness, stability, efficiency, maintainability, and user experience when designing mobile systems.
This role requires deep expertise in mobile development, C++, and emerging AI technologies. You will work on cutting-edge infrastructure that powers Binance's mobile ecosystem.
