Machine Learning Engineer, Inference & Serving (Speech LLM)

Machine Learning Engineer, Inference & Serving (Speech LLM) — San Francisco, CA (Hybrid) Overview We are looking for a Machine Learning Engineer, Inference & Serving (Speech LLM) to build and deploy high-throughput, ultra-low-latency inference systems for large language models and foundational speech models. You may be a good fit if you: Have hands-on experience building and deploying high-throughput, ultra-low-latency inference engines for large language models or foundational speech models.

Understand the intricate tradeoffs between latency, throughput, and Time-To-First-Token (or Time-To-First-Audio) in real-time streaming environments. Have practical experience with continuous batching, KV cache management (e.g., Paged. Attention), and stateful connections necessary for real-time conversational AI. Possess a deep understanding of GPU architectures (NVIDIA Ampere/Hopper) and the memory hierarchy, allowing you to identify and eliminate hardware bottlenecks.

Communicate clearly and collaborate effectively, as you will sit at the critical intersection between the core ML training team and the backend infrastructure team. Thrive in fast-moving environments and genuinely enjoy the systems-engineering challenge of squeezing every last drop of performance out of a cluster of GPUs.

Are obsessed with building AI systems that natively understand and generate speech. Strong candidates may also have experience with: Frontier Serving Frameworks: Deep, under-the-hood familiarity with modern LLM serving frameworks like vLLM, TensorRT-LLM, SGLang, or NVIDIA Triton Inference Server (bonus points for active open-source contributions to these repositories).

Real-Time Audio Streaming: Experience handling continuous audio streams over Web. Sockets or WebRTC, deploying neural audio codecs, and managing chunked audio generation to minimize conversational latency. Advanced Inference Techniques: Implementing cutting-edge generation algorithms such as speculative decoding, lookahead decoding, or chunked prefill.

Model Compression & Quantization: Hands-on experience with post-training quantization (PTQ), deploying models in FP8, INT8, AWQ, or GPTQ, without degrading audio naturalness or ASR accuracy. Large-Scale Distributed Systems: Deploying multi-GPU (Tensor Parallelism) and multi-node inference pipelines, and managing autoscaling infrastructure using Kubernetes.
