HPC Engineer

HPC Engineer About Vsora : VSORA is a French fabless semiconductor company delivering ultra-high-performance AI inference solutions for both data centers and edge deployments. Our proprietary architecture achieves exceptional implementation efficiency, ultra-low latency, and minimal power draw - dramatically cutting inference costs across any workload. Fully programmable and agnostic to both algorithms and host processors, our chips serve as versatile companion platforms.

A rich instruction set lets them seamlessly handle pure AI, pure DSP, or any hybrid of the two, all without burdening developers with extra complexity. To streamline development and shorten time-to-market, VSORA embraces industry standards: our toolchain is built on LLVM and supports common frameworks like ONNX and PyTorch, minimizing integration effort and customer cost. Based in the outskirts of Paris, France, the company was founded in 2015 by a team of highly qualified and accomplished AI/DSP experts and entrepreneurs.
