Résumé du poste

IMCS Group in Cupertino, CA is seeking a results-driven Image Quality Engineer to diagnose and tune ISP pipelines. You will reproduce image quality issues, perform lab testing, and collaborate across hardware, firmware, and software teams to improve color accuracy, sharpness, HDR, and noise performance.

The role requires hands-on testing, familiarity with MTF/SFR, color science, EXIF metadata, and scripting for data analysis.

Qualifications

• Hands-on experience in image quality, camera testing, optical metrology, or imaging.
• ISP tuning experience with platforms such as Qualcomm Spectra, MediaTek Imagiq, or similar.
• MTF/SFR measurement and slanted-edge methodology knowledge.
• Color science, CRI, color temperature and ICC color management understanding.
• Camera/sensor pipeline fundamentals including Exposure, HDR, NR, 3A, sharpening, and tone mapping.
• EXIF metadata handling and image quality test conditions familiarity.

Responsabilités

• Reproduce customer-reported image quality issues such as color shift, low-light noise, MTF/sharpness degradation, HDR artifacts, and banding
• Diagnose root causes of image quality issues through controlled lab testing and analysis
• Perform ISP tuning including AE, AWB, AF, noise reduction, sharpening, tone mapping, and HDR fusion
• Adapt and port tuning parameters and calibration workflows across different ISP platforms
• Design and execute image quality test protocols using SFR/slanted-edge charts, ColorChecker targets, and standardized test charts
• Build and maintain real-world image failure sample libraries and correlate EXIF metadata with lab test conditions
• Conduct subjective and objective image quality evaluations
• Collaborate with hardware, firmware, algorithm/tuning, and customer support teams to resolve imaging issues
• Document test methodologies, tuning changes, findings, and recommendations
