Software Engineer - Android OS (AOSP)

About Soverli Smartphones are one of the last unclaimed frontiers of digital sovereignty. Today, achieving true control over the mobile software supply chain comes at a prohibitive cost: giving up convenience and access to modern app ecosystems. This creates structural risks for governments, critical infrastructure, and enterprises that depend on smartphones to operate securely. Even for individuals seeking greater control and more privacy, the only option today is to abandon everyday usability by running a phone with an alternative operating system — a trade-off few can realistically afford to make. At Soverli, we are on a mission to eliminate this trade-off by making digital freedom and sovereignty on smartphones convenient and accessible to everyone. We are building a patent-pending platform that enables multiple, fully isolated operating environments to run in parallel on smartphones. This unlocks true privacy, freedom, and security — without compromise: users retain the complete Android experience for everyday use and can switch, in milliseconds and at the press of a button, to a customizable, private operating system they fully own and control. By rethinking how operating systems can coexist on mobile devices, we are laying the foundation for a new wave of secure, privacy-focused, and user-centric mobile innovation. Your role As an AOSP engineer at Soverli, you will shape how Android behaves in a system where multiple OS instances coexist securely on one smartphone. You will work on Android’s internals - from system services to HALs and platform security. In particular, you will: Customize and extend AOSP at the framework, system, and runtime layers. Integrate hardware abstraction layers (HALs) with system services and platform components. Implement OS-level privacy and security features. Optimize memory usage, system performance, and power behavior across complex multi-OS setups. Debug system behavior across Android services, logs, and performance traces (logcat, systrace, Perfetto). Work closely with kernel, firmware, and driver engineers to ensure seamless hardware–software interaction. Contribute to Soverli’s CI, automated system tests, and Android build infrastructure. Your profile You have: Strong programming skills in C/C++ and familiarity with Java/Kotlin in system contexts. Solid understanding of AOSP internals - Binder IPC, system services, HALs. Experience with Android platform development, device bring-up, or custom ROMs. Practical knowledge of low-level debugging tools (logcat, systrace). Understanding of OS concepts: processes, memory, scheduling, security boundaries. A BSc or MSc in Computer Science, Electrical Engineering, or related field. Fluent English and strong communication skills. Nice to have: Contributions to AOSP or Android security/privacy projects. Experience with Android connectivity/power subsystems. Familiarity with building and maintaining custom Android ROMs. Why join us Work with a passionate founding team on cutting-edge technology with high real-world impact.
