Responsibilities
Build and optimize LLM serving and inference systems for production environments
Improve performance across GPU and CPU pathways
Work on KV cache, memory, storage, and throughput bottlenecks
Design and scale systems that support RAG and retrieval-heavy AI workloads
Contribute to infrastructure where storage architecture and systems efficiency materially affect AI performance
Solve engineering problems at the intersection of AI, high-performance systems, and distributed infrastructure
Qualification
Required
An engineer who has spent meaningful time building or optimizing production AI systems, not just experimenting with models
Someone who understands how inference performance is shaped by the interaction between compute, memory, storage, and serving architecture
Deep hands-on experience working close to the systems layer — for example, improving how workloads run across GPU and CPU resources, reducing bottlenecks, or tuning infrastructure for better throughput and latency
Evidence of real ownership in areas like model serving, retrieval, caching, storage, or distributed performance, rather than purely application-layer AI work
The ability to move comfortably between architecture decisions and hands-on implementation, especially in environments where efficiency and scale matter
A background that suggests you can operate in technically demanding environments, whether that comes from AI infrastructure, high-performance systems, storage platforms, or adjacent distributed systems work
Preferred
PhD preferred, but far less important than having built serious systems in the real world
Company
