Member of Technical Staff

ABOUT THE ROLE Join an early-stage AI infrastructure team building systems that improve the performance and efficiency of open-source model inference. This role spans low-level optimization and production operations, helping deliver fast, reliable inference across diverse hardware. WHAT YOU'LL DO - Bring new open-source models into production with optimizations for latency and throughput. - Improve inference serving through batching, KV cache management, speculative decoding, and quantization. - Write and tune GPU kernels using CUDA, HIP, and Triton across a range of accelerator platforms. - Design, deploy, and operate heterogeneous clusters across infrastructure providers. - Run production inference across mixed hardware fleets, improving reliability, observability, and cost efficiency. - Work with customers to understand needs and solve infrastructure performance problems. WHAT WE'RE LOOKING FOR - Approximately 1 to 6 years of experience in backend, infrastructure, or systems engineering, including low-level work beyond application development; strong early-career candidates are welcome. - Understanding of computer architecture, memory hierarchies, and operating system internals. - Experience operating infrastructure at scale, such as clusters, data centers, or GPU fleets. - Familiarity with machine learning inference optimization, including quantization, batching, KV caches, or speculative decoding. - Experience with CUDA, Triton, or other GPU programming, with Python and exposure to technologies such as HIP, TPU, or AWS Trainium useful. - Strong CS fundamentals, evidence of rapid learning or ownership of challenging systems, and experience using AI coding tools to improve workflows. - Comfort working directly with customers and taking broad ownership in a small team. COMPENSATION & BENEFITS Base salary: $200,000 to $300,000 annually. Visa sponsorship is available. LOCATION On-site in San Francisco, California.
