Solve the hardest problems in compute
Building the Future of High-Performance Compute
We're a team of builders, mathematicians, and systems thinkers driven by a singular mission: to reinvent how the world computes. From our Kernel Optimizer to the Tensor Cloud, we're designing the foundation for modern AI and HPC by making computation faster, cheaper, and more portable across every platform.
At SF Tensor, technical depth isn't optional. It's the core of how we solve real performance bottlenecks and collaborate internally. No matter your role, you'll be expected to engage deeply with the technology.
If you want to push hardware to its limits, design languages that reimagine what's possible, and help define the next era of high-performance software, you belong here.

Your model is the advantage. Infrastructure shouldn’t be the constraint.
Bring the model, data, and ambition. We’ll optimize the kernels, orchestrate the fleet, and deliver the training outcome.
Train the models only you can build. One stack for enterprise post-training and frontier pre-training.
