Experience :

Required Skills

• Camera Driver Development & Integration :
• Develop, maintain, and enhance V4L2 (Video4Linux2) camera drivers.
• Integrate camera sensors (e.g., Sony, Omnivision) with ISP (Image Signal Processor) pipelines.
• Enable sensor features and support sensor initialization, streaming, and control operations on embedded Linux.
• Middleware & HAL Layer Implementation :
• Develop and adapt camera HAL (Hardware Abstraction Layer) for Linux or Android platforms.
• Interface camera hardware with middleware stacks like GStreamer, libcamera, or vendor-specific solutions.
• Work on device tree configuration and kernel-to-user-space interfacing.
• Camera Tuning & Optimization :
• Tune ISP parameters such as :
• Auto White Balance (AWB)
• Auto Exposure (AE)
• Auto Focus (AF)
• Collaborate with ISP algorithm teams to improve image quality under various lighting and scene conditions.
• Debugging & Validation :
• Bring-up new camera modules on custom hardware.
• Analyze logs and debug camera stack using tools like :
• media-ctl, v4l2-ctl
• GStreamer pipelines
• Custom test frameworks
• Validate image quality and camera performance.
• Performance Optimization :
• Optimize latency, throughput, and power consumption of the camera pipeline.
• Benchmark and profile performance for real-time or low-power applications.
• Collaboration with Cross-Functional Teams :
• Coordinate with teams across hardware, kernel, middleware, and user-space applications.
• Work closely with SoC vendors and camera module suppliers for feature enablement and issue resolution.
• Support for Multi-Camera Systems :
• Enable and synchronize multi-camera use cases such as :
• Stereo vision
• 360 and surround-view systems
• Multi-sensor streaming and fusion
  

Expertise Required

• Programming Skills :
• Proficient in C/C++ for kernel and user-space development.
• Experience with multithreading, performance optimization, and memory handling in embedded systems.
• Linux & Embedded Systems :
• Solid background in Embedded Linux environments.
• Hands-on with Yocto, Buildroot, or AOSP for building Linux/Android images.
• Camera Frameworks & APIs :
  

• Familiarity with libcamera, GStreamer, and camera pipeline development.
• Image Signal Processing (ISP) :
• Understanding of ISP components (3A: Auto Focus, Auto Exposure, Auto White Balance).
• Experience with image tuning tools and workflows.
• Sensor Interfaces :
• Strong understanding of MIPI CSI-2, I2C, and camera module interfacing.
• Experience with low-level sensor bring-up and timing/debugging tools (e.g., logic analyzers, scope).
• Debugging & Profiling :
• Proficient with tools: dmesg, strace, gdb, perf, media-ctl, v4l2-ctl.
• Ability to trace and resolve kernel/user-space interaction issues.
• Android-Specific Knowledge (if applicable) :
• Familiar with Camera HAL3, AOSP camera stack, and Android camera debugging tools (logcat, camera_dbg)
