Machine Learning Researcher (Speech/Audio)

Key Responsibilities

• Research and develop state-of-the-art voice synthesis models (e.g., TTS, voice cloning, speech-to-speech).
• Build and fine-tune models using frameworks like PyTorch and HuggingFace.
• Design training pipelines and datasets for scalable voice model training.
• Explore techniques for emotional expressiveness, multilingual synthesis, and speaker adaptation. 
• Work closely with product and creative teams to ensure models meet quality and production constraints. 
• Stay on top of academic and industrial trends in speech synthesis and related fields.

Must Haves

• Strong background in machine learning and deep learning, with focus on speech/audio.
• Hands-on experience with TTS, voice cloning, or related voice synthesis tasks.
• Proficiency with Python and PyTorch; experience with libraries like torchaudio, ESPnet, or similar.
• Experience training models at scale and working with large audio datasets.
• Familiarity with vocoders and transformer-based architectures.
• Strong problem-solving skills, ability to work autonomously in a remote-first environment.

Nice to Have

• PhD degree in Computer Science/ Machine Learning and publications in top venues. 
• Contributions to open-source speech research or participation in relevant benchmarks. 
• Familiarity with adjacent areas like lip-syncing, audio-driven animation, or expressive speech control. 
• Experience with voice datasets or proprietary pipelines.
