About the Role

We are looking for a senior technical leader to help define and drive the architecture for a new tiered memory system for Android and embedded Linux devices.
This person will guide the technical direction across Linux memory management, compressed memory, swap, Android platform behavior, storage-backed memory, and real‑device performance. The right candidate should be both architectural and hands‑on — someone who can reason about the full system, review kernel code, debug difficult issues, and mentor the rest of the team.

Primary responsibilities

• Define the architecture for a tiered memory system using technologies such as zram, zswap, swap, cgroups, and storage‑backed memory.
• Lead design discussions around memory policy, app-priority behavior, read/write paths, storage placement, and prefetch strategies.
• Review kernel and Android platform changes for correctness, performance, maintainability, and production readiness.
• Help the team understand tradeoffs between latency, memory capacity, NAND endurance, CPU usage, and user experience.
• Work closely with kernel, Android platform, validation, and storage engineers.
• Provide technical leadership for a small, focused engineering team.
• 10+ years of experience in Linux kernel, Android kernel, embedded Linux, firmware, or platform architecture.
• BS/MS degree in Computer Science or equivalent experience
• Strong understanding of Linux memory management, swap, reclaim, page faults, and cgroups/memcg.
• Strong C programming and kernel debugging background.
• Experience working with real hardware, not just simulation or emulation.
• Ability to debug complex cross-layer issues involving kernel, Android userspace, storage, and performance.
• Strong communication skills and the ability to explain technical tradeoffs clearly.

Preferred qualifications

• Experience with zram, zswap, compressed memory, or swap optimization.
• Android GKI/KMI experience.
• Android phone, TV, tablet, or embedded product experience.
• UFS, eMMC, NAND, FTL, HPB, WriteBooster, or storage QoS experience.
• Experience with Android LMKD, app lifecycle, or system performance tuning.
