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., PagedAttention), 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, ultimately creating a hardware-software AI companion that amplifies human productivity. 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 WebSockets 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. WHAT WE OFFER - Founding Team Initiative: Opportunity to be an early, foundational member of our core SpeechLLM lab, with meaningful ownership and impact on a fast-growing startup. - Competitive Compensation: $180K - $270K base salary + performance bonus + Equity. - Comprehensive Benefits: Top-tier healthcare for employees and dependents, including dental and vision, and a generous employer subsidy. - Retirement Planning: 401(k) plan for full-time employees with company matching. - Paid Time Off: Unlimited PTO, plus 13 paid holidays. - New Parent Leave: 12 weeks of paid time off to spend time with your new family, regardless of gender. - Hybrid Office: Minimum of 3x in-office per week to foster highly collaborative, fast-paced research. - Gear & Perks: Choice of top-of-the-line laptops/workstations, annual offsites, and a fully stocked office.
