• Perform board bring‑up (U‑Boot, device tree, kernel integration).
• Conduct low‑level debugging using UART, JTAG, and similar tools.
• Modify Linux kernel components and device drivers when required.
• Improve system performance, resource usage, and inter‑process communication (Binder/AIDL).
• Use system‑level profiling tools to identify and fix issues.
• Fix OS‑ and kernel‑level vulnerabilities and Reduce OS/kernel attack surfaces.
• Implement OTA update mechanisms.
• Support cybersecurity risk analysis and threat modeling.
• Perform OS‑level verification and validation following IEC 62304.
• Support risk management efforts aligned with ISO 14971.
• Participate in audits and reviews to maintain regulatory compliance.
• Work with app developers to ensure compatibility.
• Partner with cybersecurity, system engineering, and quality teams.
• Create and maintain architecture docs, test plans, and traceability matrices.
• Ensure documentation is complete and audit‑ready.
Required Qualifications
• Bachelor’s or Master’s degree in Computer Engineering, Computer Science, Electrical Engineering, or related field.
• 7+ years of software engineering experience.
• 3+ years working with Android OS / AOSP.
• Strong experience with AOSP builds, Android frameworks, and kernel modification.
• Solid understanding of Linux internals and embedded systems.
• Experience in regulated environments.
• Knowledge of IEC 62304, ISO 14971, and related standards.
• Familiarity with cybersecurity risk assessment and vulnerability remediation.
Preferred Qualifications
• Experience with legacy Android (Android 5).
