Job Description
As a Senior Android Developer, you will lead the architectural design and core module development of our company's Android application, ensuring optimal performance, security, and stability. You will be responsible for mobile architecture upgrades and modular transformations, including dynamic loading, componentization, hotfix solutions, and A/B testing frameworks. Additionally, you will play a key role in designing security systems such as single-device login restrictions, anti-decompilation measures, data encryption, and device fingerprint recognition.
Collaborating closely with product, design, and backend teams, you will drive continuous improvements in user experience and interaction details. You will also contribute to the research and implementation of authentication solutions like Passkey/FIDO2, WebAuthn, and biometric verification. Performance optimization—covering app launch speed, package size, battery consumption, and memory usage—will be a critical part of your role.
Furthermore, you will mentor junior and mid-level engineers through code reviews, performance tuning, and technical training to foster team growth. Staying updated with cutting-edge technologies (Flutter, HarmonyOS, Compose, Kotlin Multiplatform) and advocating for their adoption when appropriate will also be part of your responsibilities.
