Senior Principal Architect - Window System

About the role

Huawei Canada has an immediate permanent opening for a Senior Principal Architect. The web, Windowing and Graphics team is exploring novel architectures to accelerate the rendering of ArkUI and web platform content.

Key responsibilities

• Lead the development of the 2D rendering technology stack and windowing system for terminal operating systems, driving performance optimization under heavy‑load scenarios while reducing power consumption and system load.
• Drive research and innovation for next‑generation 2D rendering technologies, including architectural exploration and implementation such as dynamic fixed‑function pipelines and data‑driven rendering approaches.
• Design and build the desktop environment of the windowing system to support ecosystem development, delivering a cross‑platform, high‑performance, low‑power desktop experience.

Required profile

• Strong understanding of operating systems, including foreground/background resource allocation, CPU/GPU/DDR scheduling, frequency scaling, process/thread management, and user‑mode vs kernel‑mode transitions.
• Deep knowledge of 2D graphics and rendering, familiar with window management, rendering, and composition pipelines in Android, Linux, and iOS, and able to analyze runtime pipelines for bottlenecks and power‑efficiency trade‑offs.
• Understanding of desktop environments such as GNOME and KDE, with clear insight into module responsibilities and their impact on system performance and user experience.

Required skills

• GPU driver development and customization.
• Chrome rendering architecture expertise.
• Experience with Huawei HarmonyOS integration.
• 2D rendering technology stack design.
