Senior Linux Kernel Camera/ISP Driver Engineer

Senior Linux Kernel Camera/ISP Driver Engineer

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.

Required:


- 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.
- Solid understanding of Linux power management (runtime PM and suspend/resume).

Preferred:


- Familiarity with vendor-specific GPU driver stacks, TTM memory models, and firmware mailbox protocols.
- Experience with automotive-grade reliability standards (such as ISO 26262).
- A track record of active contributions to the upstream Linux kernel.
