C++ / systems engineer

We are looking for a strong senior C++ / systems engineer for a difficult refactoring project in a production real-time AI vision system.
Current stack / context includes:
* modern C++
* real-time video / panorama processing
* computer vision / detections
* GPU-related components such as CUDA / TensorRT
* renderer / geometry / camera-behavior related logic
* legacy code that needs structured refactoring, not a rewrite

We already have internal AI / model / post-processing ownership. What we are missing is strong C++ / systems / architecture support.

We are looking for someone with:
* very strong C++
* experience refactoring legacy production systems
* real-time / low-latency systems thinking
* strong ownership / data flow / architectural judgment
* ideally some exposure to CUDA, TensorRT, OpenCV, video or rendering-related systems
