Senior Audio Data Scientist (Research)
Remote, Europe3-5 days per week
€70,000 - €100,000 salary (or equivalent compensation)

Sentinel is partnering with a specialist team working at the cutting edge of speech AI and clinical research. Their work sits at the intersection of acoustic engineering, machine learning and regulated clinical environments.
This is a senior individual contributor role with two core objectives: producing credible, publishable research that validates the science externally, and building the models and pipelines that power the product internally.

Responsibilities:

• Building and improving audio and transcript processing pipelines - segmentation, noise reduction, feature extraction
• Extracting acoustic, prosodic and linguistic features: pitch, speech rate, pauses, jitter, shimmer, spectral features, sentiment and more
• Developing models that map signals to behavioural indicators and well-being scores
• Fine-tuning and integrating LLMs for conversation summarisation, signal labelling and emotion assessment
• Designing validation studies and contributing to publications, reports and clinical evidence packages

Requirements:

• Research background, including publishing and presenting
• Hands-on experience with raw audio data and speech processing tools (such as librosa, Kaldi, Praat)
• Strong in ML frameworks (PyTorch, TensorFlow, scikit-learn) and experienced with LLMs end-to-end
• PhD or similar depth of experience in speech technology, acoustics, ML or computational linguistics (desirable)
