Job description
About the Role
Join a small AI infrastructure team working to improve the speed and efficiency of large language model inference. You will build and operate systems that optimize models across a range of hardware, with ownership spanning low-level engineering and production operations.
What You'll Do
Deliver day-one support for new open-source models, tuning them for latency and throughput.
Improve inference serving through techniques such as batching, KV caching, speculative decoding, and quantization.
Write and optimize GPU kernels using CUDA, HIP, and Triton across diverse accelerator platforms.
Design, deploy, and operate heterogeneous clusters across hardware vendors.
Run production inference across mixed hardware fleets, improving reliability, observability, and cost per token.
Work directly with customers as part of solving infrastructure and performance challenges.
What We're Looking For
Typically 1 to 6 years of experience in backend, infrastructure, systems, or related engineering work; strong early-career candidates are welcome.
Strong understanding of computer architecture, memory hierarchy, and operating system internals beyond application-level development.
Experience with low-level or systems engineering, plus familiarity with Python and GPU programming tools such as CUDA or Triton; HIP experience is also relevant.
Knowledge of ML inference optimization, including quantization, batching, KV caches, or speculative decoding.
Experience deploying or operating large-scale infrastructure, clusters, data centers, or GPU fleets.
Strong computer science fundamentals, demonstrated ownership of complex systems, and an interest in using AI coding tools to improve engineering workflows.
Comfort working directly with customers and contributing across a broad range of technical problems.
Compensation & Benefits
Base salary: $200,000 to $300,000 annually. Visa sponsorship is available.
Location
On-site in San Francisco, California.
