We are looking for a Senior Android Engineer (AOSP) to join our team working on innovative e-Ink based devices. This is a hands-on engineering role focusing on Android Open Source Project (AOSP)–based applications and frameworks, with responsibilities ranging from system-level development to user-facing apps (e.g. notes, documents, system UI). The role combines maintenance, stabilization, and knowledge transfer with opportunities to contribute to new features and performance optimizations in future releases.
You will collaborate closely with cross-functional teams (backend, QA, DevOps, UX) and participate in codebase onboarding, technical documentation, and feature enhancements. This role requires comfort working in a multi-vendor, multi-component environment with strong emphasis on quality, security, and maintainability.
Responsibilities:
Develop, maintain, and optimize Android applications (Notes, PDF/EPUB Reader, Home/Launcher, SystemUI). Customize AOSP components (system UI, secure storage, OTA workflows, device APIs). Implement secure coding practices (data encryption, obfuscation, authentication). Support knowledge transfer: documenting code flows, onboarding new engineers, and collaborating with existing vendor teams. Debug, stabilize, and improve performance of apps under device constraints (RAM limits, E-Ink refresh). Work with companion services (cloud sync, REST APIs) to ensure seamless user experience. Participate in code reviews, ADR discussions, and CI/CD pipelines (GitLab, automated testing). Collaborate with UI/UX experts to adapt Android UI for e-Ink hardware specifics. Contribute to incremental features such as analytics, QR sharing, audio recording, or pen integration in alignment with roadmap priorities.Requirements:
5+ years of Android development with Kotlin/Java. Strong experience with AOSP, Android frameworks, and system-level customization. Proficiency in secure data storage, dependency injection, networking, and asynchronous programming. Experience working with system updates and OTA mechanisms. Background in custom hardware integration (input devices, sensors, displays). Proven track record of debugging and performance tuning under constrained environments. Familiarity with CI/CD pipelines and Agile practices. Good English communication skills (written & spoken).Nice to have:
Experience with e-Ink devices or other embedded Android hardware. Exposure to Wacom WILL SDK, Ink Canvas, MyScript SDK, or PDF/EPUB libraries. Background in reverse engineering or legacy code takeover projects. Experience with cloud integrations (AWS, Keycloak, content sync). Previous involvement in knowledge transfer projects.Personal Attributes:
Strong problem-solving mindset, able to work with partially documented systems. Collaborative, proactive communicator in distributed international teams. Quality-driven, with attention to detail and security. Curious and adaptable — able to learn from existing codebases quickly.We offer*:
