We move fast. We build boldly. We execute with purpose. And we do it together.

? About the role





As an R&D; Engineer focused on neural network architectures for YOLO, you'll design and develop the neural network architectures at the core of how YOLO is built. Your work will directly shape the open-source models used by millions of developers across detection, segmentation, pose, and emerging vision tasks.

You'll operate at the intersection of research and production, turning ideas from papers into performant architectures, rigorous experiments, and production-ready model designs. Working closely with our cross-disciplinary R&D; team, you'll help define future releases across the Ultralytics ecosystem and contribute to the technical foundations documented in our docs and guides.

This role is adecuado for a hands-on researcher who thrives on first-principles thinking, rapid experimentation, and high ownership. You bring deep architectural intuition, strong PyTorch skills, and the drive to build original models that advance the state
