Mountain View, California, USA · Senior · Full-time · Posted Oct 23, 2026
- Education
- PhD in CS, Physics, or Math, or equivalent practical experience building backend or ML systems.
About the job
Build and optimize reliable, high-throughput, low-latency inference systems for AI models in production.
What you'll do
- Optimize model serving and inference performance, including GPU utilization, latency, and throughput.
- Scale and maintain distributed, multi-GPU or multi-node inference systems for production workloads.
- Own the model-serving lifecycle, from containerization and optimization to reliable production operation.
What they ask for
- Deep understanding of modern inference serving frameworks and optimization techniques.
- Proficiency in C++, CUDA, Rust, or highly optimized Python, including profiling and optimizing NVIDIA GPU code.
- Experience with distributed systems and scaling, such as Kubernetes, Ray, load balancing, or multi-GPU/multi-node inference.
- PhD in CS, Physics, or Math, or equivalent practical experience building backend or ML systems.
Nice to have
- Non-trivial systems programming projects, major inference-engine open-source contributions, or deep-dive technical write-ups.
- Hands-on experience with quantization, distillation, caching strategies, continuous batching, paged attention, or speculative decoding.
