Job Description Job Description Embedded Linux Kernel & MIPI Validation Engineer San Jose, CA, USA Full-Time Role Overview We are seeking a highly skilled engineer with deep expertise in MIPI protocol validation , SoC bring-up , and Linux kernel driver development . The ideal candidate will have strong hands?on experience working with display/camera interfaces, high?speed PHYs, and system-level debugging on real hardware. This role requires working across hardware, firmware, and kernel layers to ensure robust interface performance and system stability. Key Responsibilities MIPI Protocol Validation Perform deep-dive validation of MIPI D?PHY, C?PHY, DSI?2, and CSI?2 protocols. Use oscilloscopes, protocol analyzers, and logic analyzers to verify: Packet formats and ECC/CRC validation HS/LP transitions and timing parameters Lane calibration, skew, and signal integrity Debug PHY issues involving voltage swing, termination, clocking, and synchronization. Cross?Platform Bring?Up Lead initial power?on , bootloader bring-up , and low?level hardware initialization for new boards. Work across various SoC platforms to validate connectivity, pinmux, clocks, resets, and peripheral initialization. Conduct board?level electrical checks and assist with hardware debugging. Linux Kernel Development Develop, port, and optimize Linux kernel drivers in DRM/KMS (Display) or V4L2 (Camera). Debug kernel crashes, panel bring?up issues, and synchronization errors. Work with kernel logs, traces, and low-level kernel subsystems. Display & Camera Interface Management Implement and debug DSI Command Mode (DBI) and Video Mode (DPI) bring-up. Validate TE (Tearing Effect) synchronization and frame update behavior. Work with camera sensor initialization, link validation, and frame data integrity. System Configuration & Debug Develop and maintain .dtsi / .dtbo device tree files for: Power sequencing Reset trees PLL and high?speed clock configuration GPIO/pinmux definitions Troubleshoot system-level issues across hardware, kernel, and middleware layers. Required Skills & Experience Strong understanding of MIPI D?PHY, C?PHY, DSI, CSI?2 standards. Experience with oscilloscope probing , high-speed signal validation, and SI fundamentals. Proficiency in Linux kernel debugging , driver development, and board bring?up. Hands-on experience with protocol analyzers, logic analyzers, and lab equipment. Ability to read schematics, PCB layouts, and debug electrical-level issues. Experience with display panels, camera sensors, or SoC multimedia subsystems. Good to Have Experience with panel timing , display drivers, LED drivers, or imaging pipelines. Understanding of bootloaders (U-Boot), firmware initialization, or RTOS. Exposure to scripting (Python, Bash) for automation or test frameworks. Knowledge of signal integrity concepts (impedance, skew, jitter, eye diagram basics).
