Summary
👤
SeniorJames Mccombe is a Technical Director in San Francisco with 20+ years of deep technical leadership and 12 years of senior industry experience building graphics, imaging, and performance-optimized systems. He bridges software and hardware architecture at Apple, focusing on graphics, displays, power and performance, after founding and scaling multiple startups including Caustic Graphics and ViewMagic. James has architected real-time ray tracing hardware/software pipelines, implemented high-performance GPU ISPs and 6DOF streaming video for AR/VR, and shipped production renderers used in consumer devices. His career blends hands-on low-level engineering—assembly-optimized DSP renderers and on-chip BVH algorithms—with strategic integration across GPU architecture, drivers and firmware. He’s known for solving awkward practical problems such as eye-contact in video calling by moving the camera virtually behind displays and for automating sub-pixel camera calibration at UHD resolutions. That combination of systems-level vision and detailed algorithmic craftsmanship makes him effective at turning research-grade ideas into manufacturable products.
