Job description

We are looking for a passionate and energized engineer to accelerate the integration of APIs across the CUDA-X math library software stack into modern LLM and agentic AI workflows. Leading organizations globally are using GPU-powered data centers for AI, data analytics, and scientific simulations, driving advancements in fields like LLMs, computer vision, CAE, EDA, and autonomous vehicles. Our team develops the GPU-accelerated libraries and SDKs essential for these technologies.

In this role, you will be responsible for ensuring both human engineers using LLMs and AI agents alike to build high-performance applications with ease through effective utilization of CUDA-X libraries. Do you have the rare blend of technical, developer experience and communication skills? If so, we would love to learn more about you!

What You'll Be Doing

• Drive the architecture and implementation of math libraries APIs and documentation structures designed to be LLM-first: introspectable, explainable, and easily synthesized by AI agents.
• Work with internal and external stakeholders to deliver timely LLM-enhanced library releases.
• Build metrics, tools and processes to measure impact and quality of LLM/agentic code generation.
• Prototype tooling and solutions to help transform math libraries' APIs into LLM-friendly representations across popular codegen tools.

What We Need To See

• PhD or MSc's degree in Computational Science, Computer Science, Applied Math, or related science or engineering field of study is preferred (or equivalent experience)
• 3+ years of experience
• Robust knowledge of LLMs, finetuning, RL, building RAGs, MCP, and building agenting tooling
• Proven experience designing clear, composable APIs and writing high-quality, well-documented code for complex technical domains
• Ability to prioritize multiple projects and work independently with minimal direction
• Excellent collaboration, communication, and documentation habits

Ways To Stand Out From The Crowd

• Prior work in AI-assisted software engineering, code generation, or programming language design
• Familiarity with CUDA-X math library APIs: cuBLAS, cuFFT, cuSOLVER, cuSPARSE, etc.
