NVIDIA is looking for an expert software engineer to help us expand our catalog of Device eXtension (Dx) APIs for our math libraries. For over a decade, NVIDIA's accelerated computing platform has revolutionized HPC and AI with applications ranging from COVID-19 research to autonomous machines. Did you know that our team develops the GPU-accelerated mathematical libraries that make all of this possible? The hardware and software accelerated computing ecosystem is constantly evolving, including shifts towards hybrid backends, deep integration with high-level languages and ecosystems (such as Python, Numpy, JAX, MLIR), and optimization at runtime for maximum flexibility and performance. Our Dx APIs allow developers to embed highly-optimized mathematical operations in their applications for these and other scenarios.

Company Description - Bicycle Therapeutics is a clinical-stage pharmaceutical company developing a novel class of medicines, referred to as Bicycle molecules, for diseases that are underserved by existing therapeutics. Bicycle molecules are fully synthetic short peptides constrained with small molecule scaffolds to form two loops that stabilize their structural geometry. This constraint facilitates target binding with high affinity and selectivity, making Bicycle molecules attractive candidates for drug development. The company is evaluating zelenectide pevedotin (formerly BT8009), a Bicycle Drug Conjugate (BDC) targeting Nectin-4, a well-validated tumor antigen; BT5528, a BDC molecule targeting EphA2, a historically undruggable target; and BT7480, a Bicycle Tumor-Targeted Immune Cell Agonist (Bicycle TICA) targeting Nectin-4 and agonizing CD137, in company-sponsored
