## About the Role

Artificial Intelligence (AI), Audiovisual, Memory Hardware, GPU (Graphics Processing Unit), Open Source, Resource Management, Load Balancing, Compensation and Benefits, Network Operations Center, Data Modeling, * 5+ years of demonstrated experience building large-scale, fault-tolerant, distributed systems and API microservices.

 * Strong background in designing, analyzing, and improving efficiency, scalability, and stability of complex systems.
 * Excellent understanding of low-level OS concepts: multi-threading, memory management, networking, and storage performance.
 * Expert-level programming in one or more of: Rust, Go, Python, or TypeScript.
 * Knowledge of modern LLMs and generative models and how they are served in production is a plus.
 * Experience working with the open source ecosystem around inference is highly valuable; familiarity with SGLang, vLLM, or NVIDIA Dynamo will be especially handy.
 * Experience with Kubernetes or container orchestration is a strong plus.
 * Familiarity with GPU software stacks (CUDA, Triton, NCCL) and HPC technologies (InfiniBand, NVLink, MPI) is a plus.
 * Bachelor's or Master's degree in Computer Science, Computer Engineering, or related field, or equivalent practical experience.

## Description

* Build and optimize global and local request routing, ensuring low-latency load balancing across data centers and model engine pods.
 * Develop auto-scaling systems to dynamically allocate resources and meet strict SLOs across dozens of data centers.
 * Design systems for multi-tenant traffic shaping, tuning both resource allocation and request handling - including smart rate limiting and regulation - to ensure fairness and consistent experience across all users.
 * Engineer trade-offs between latency and throughput to serve diverse workloads efficiently.
 * Optimize prefix caching to reduce model compute and speed up responses.
 * Collaborate with ML researchers to bring new model architectures into production at scale.
 * Continuously profile and analyze system-level performance to identify bottlenecks and implement optimizations.
