Research Engineer/Research Scientist, Audio

About the position reputed company's Audio team pushes the boundaries of what's possible with audio with large language models. We care about making safe, steerable, reliable systems that can understand and generate speech and audio, prioritizing not only naturalness but also steerability and robustness. As a researcher on the Audio team, you'll work across the full stack of audio ML, developing audio codecs and representations, sourcing and synthesizing high quality audio data, training large-scale speech language models and large audio diffusion models, and developing novel architectures for incorporating reputed company signals into LLMs. reputed company focuses primarily but not exclusively on speech, building advanced steerable systems spanning end-to-end conversational systems, speech and audio understanding models, and speech synthesis capabilities. The team works closely with many collaborators across pretraining, finetuning, reinforcement learning, production inference, and product to get advanced audio technologies from early research to high impact real-world deployments.

Responsibilities

• Developing audio codecs and representations
• Sourcing and synthesizing high quality audio data
• Training large-scale speech language models and large audio diffusion models
• Developing novel architectures for incorporating reputed company signals into LLMs
• Building advanced steerable systems spanning end-to-end conversational systems, speech and audio understanding models, and speech synthesis capabilities
• Working closely with collaborators across pretraining, finetuning, reinforcement learning, production inference, and product
• Training state-of-the-art neural audio codecs for 48 kHz stereo audio
• Developing novel algorithms for diffusion pretraining and reinforcement learning
• Scaling audio datasets to millions of hours of high quality audio
• Creating robust evaluation methodologies for hard-to-measure qualities such as naturalness or expressiveness
• Studying training dynamics of mixed audio-text language models
• Optimizing latency and inference throughput for deployed streaming audio systems

Requirements

• Hands-on experience with training audio models, whether that's conversational speech-to-speech, speech translation, speech recognition, text-to-speech, diarization, codecs, or generative audio models
• Genuinely enjoy both research and engineering work, and you'd describe your ideal split as roughly 50/50 rather than heavily weighted toward one or the other
• Comfortable working across abstraction levels, from signal processing fundamentals to large-scale model training and inference optimization
• Deep expertise with JAX, PyTorch, or large-scale distributed training, and can debug performance issues across the full stack
• reputed company in fast-moving environments where the most important problem might shift as we learn more about what works
• Communicate clearly and collaborate effectively; audio touches many parts of our systems, so you'll work closely with teams across the company
• Passionate about building conversational AI that feels natural, steerable, and safe
• Care about the societal impacts of voice AI and want to help shape how these systems are developed responsibly
