What we're looking for

• Senior engineer, able to own a substantial part of an architecture and drive it forward autonomously.
• Experience building developer-facing infrastructure at an AI or developer-tools company: inference APIs, agent infrastructure, or something comparable.
• Substantial open-source contributions to a Python library. Comfortable with async Python and distributed systems, including their failure modes.
• You have shipped something realtime: streaming, WebSockets or WebRTC, audio or video pipelines, live inference.
• Practical experience with LLMs or multimodal models in production. Clear written communication and a habit of collaborating async and in public.
• Motivated by voice and conversational AI.

Bonus points if you have

• Contributions to a voice-agent framework such as speech-to-speech, pipecat, LiveKit Agents, Vocode or TEN.
• Contributions to llama.cpp or another low-level inference runtime.
• Hands-on work with ASR, TTS or end-to-end speech models, including evaluation of latency and quality trade-offs.
• GPU serving, quantization, or on-device inference experience.
• Audio pipeline knowledge: VAD, echo cancellation, jitter buffers, barge-in and turn detection.
• Experience shipping to embedded or robotics targets.
• A public track record: talks, blog posts, demos.

About You

If you're interested in joining us, but don't tick every box above, we still encourage you to apply! We're building a diverse team whose skills, experiences, and backgrounds complement one another. We're happy to consider where you might be able to make the biggest impact.

One more thing

At Hugging Face we believe great AI shouldn't require a massive cluster, we build for everyone, especially the GPU-poor. And because we read every application, here's a small sign that you read this one too: start your answer to the first application question with the words “GPU-poor and proud 🤗”. No trick, no catch, it just tells us a real person is on the other side.
