If you're creative & passionate about solving real world conversational AI problems, come join our Speech AI Engineering team.

What You'll Be Doing

Work on cutting-edge GPU-accelerated AI systems deployed at scale
Tackle challenging problems in real-time streaming audio processing and low-latency inference
Troubleshoot and resolve complex issues across ASR, TTS, ALM, and S2S pipelines
Model Integration: Work alongside Model researchers to transition ASR, TTS and S2S models from research to production readiness.
Develop Core Speech Services: Build and enhance C++ & python backend implementations for ASR, TTS, and S2S pipelines, leveraging CUDA for GPU acceleration
Optimize Inference Performance: Improve streaming latency and throughput through advanced batching strategies, encoder caching, and multi-threaded pipeline optimizations
Feature Development: Add new capabilities such as advanced voice activity detection, speaker diarization, decoder implementations (CTC, WFST, Flashlight), and text post-processing
Client Libraries: Contribute to Python and C++ client SDKs and CLI tools for easy service integration
Assist with API integration, SDK usage, model deployment, and performance optimization
Provide advanced technical guidance to customers implementing speech technology solutions
