Senior Linux Kernel Camera/ISP Driver Engineer

Job Description As a Senior Kernel Engineer, you will take ownership of a Linux camera/ISP stack centered on the chipset vendor's ISP architecture. Your work will span V4L2 media pipeline implementation, firmware command/response integration, DMA-BUF and GPU-shared memory handling, sensor/CSI bring-up, and production‑grade reliability fixes. This is a hands‑on development role requiring deep kernel‑space debugging, concurrency management, and hardware‑software co‑design. What You Will Do Develop and maintain Linux kernel camera and ISP drivers utilizing V4L2, the Media Controller framework, and videobuf2 (vb2). Integrate and debug MIPI CSI-2 sensors and image pipelines to ensure optimal routing for preview, video, and Zero Shutter Lag (ZSL) paths. Implement and maintain robust firmware interfaces, managing command/response queues, interrupt processing, and work‑thread synchronization. Manage the buffer lifecycle using MMAP, DMA‑BUF import/export, zero‑copy mechanisms, and fence signaling to minimize latency. Drive power management initiatives, including suspend/resume, runtime PM, and clock/power sequencing robustness for camera hardware subsystems. Diagnose and resolve complex kernel‑space issues such as race conditions, memory leaks, deadlocks, and frame pipeline regressions. Build debug and observability tooling using debugfs, sysfs, ftrace tracepoints, custom counters, and system health metrics. Maintain high code quality through rigorous code reviews and technical documentation while collaborating closely with chipset vendors/silicon partners, camera sensor manufacturers, and user‑space camera framework teams. Skills and Requirements 10+ years of embedded systems experience, with a minimum of 5 years dedicated to Linux kernel driver development. Expert‑level C programming in kernel space, including memory management, locking primitives (mutexes, spinlocks, RCU), workqueues, and interrupt handling. Production‑level experience with the Linux media stack (V4L2 ioctls, Media Controller entities, and videobuf2). Hands‑on experience with MIPI CSI‑2 sensor and ISP bring‑up. Strong knowledge of DMA‑BUF, scatter‑gather mapping, cache coherency, and kernel debugging tools (JTAG, GDB, ftrace, lockdep). Solid understanding of Linux power management (runtime PM and suspend/resume). Equal Employment Opportunity We are an equal opportunity/affirmative action employer that believes everyone matters.
