As a Research Engineer - Audio & Speech Models, you will be a core contributor on Zyphra's Audio Team, building the next generation of open-source autoencoders, ASR, TTS, SSL, and speech-to-speech models. You will be deeply involved in the entire model training process, from data gathering and processing to designing novel architectures and training methodologies.
You'll Work Across:
Large-scale audio training runs
Performance optimization of our training stack
Audio dataset collection, processing, and evaluation
Architecture and training methodology ablations and improvements
What Were Looking For / Requirements:
Strong research taste and intuition. The ability to work through a research project from conception to execution to write-up.
Strong implementation and prototyping ability (can take an idea from conception to experimentation quickly)
The ability to work well with others in a high-paced research setting
Excellent communication and collaboration skills, and can work effectively on both research and engineering implementation at scale
Qualifications / Additional Skills:
Expertise and intuition for training models in the audio domain, including text-to-speech, ASR, speech-to-speech, speech-emotion-recognition, or other models
Experience in training audio autoencoders
Understanding of signal processing, especially of audio signals
Experience with diffusion models, consistency models, or GANs
Experience with training on large-scale (multi-node) GPU clusters
Strong grasp of proper experimental methodology for running rigorous ablations and other hypothesis testing
Understanding of and interest in large-scale, highly parallel data processing pipelines
Proficiency with PyTorch and Python
