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.

• 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 trace points, 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.

• 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), work queues, 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).
