Zusammenfassung

Sonia seeks an experienced Machine Learning Engineer (ASR) to advance speech recognition for clinical use. You’ll design, fine-tune and deploy ASR models, build data pipelines, and collaborate with MLOps to keep production models healthy.

Ideal candidates have a Master’s in CS or Engineering, 5–8+ years in ML, and strong Python, PyTorch, and DL expertise, plus experience with Whisper and wav2vec in medical contexts. Remote or hybrid options available.

Qualifikationen

• Master’s degree in Computer Science or Engineering.
• 5-8+ years of ML engineering experience.
• Proficient in Python and production deployments.
• Experience with ASR models (Whisper, wav2vec), VAD, alignment and diarisation.
• Experience with transformer-based architectures and deep learning.
• Practical experience with MLOps components (Docker, MLflow, W&B, DVC, Kubernetes).

Aufgaben

• ASR Model Development: Fine-tune, evaluate, and deploy state-of-the-art models in speech recognition and audio processing (Whisper, wav2vec).
• Data Curation & Annotation: Collect and curate custom ASR datasets, including data sourcing, annotation pipeline setup, quality control, and alignment/segmentation procedures.
• Audio Pipelines: Build and maintain robust data pipelines and audio preprocessing workflows for clinical environments.
• MLOps Collaboration: Work closely with the MLOps team to ensure continuous training, monitoring, and deployment of models in production.
• Experimentation: Design and conduct experiments to validate new approaches, datasets, and architectures to improve accuracy in noisy or specialized medical settings.
• Cross-Functional Impact: Collaborate with product managers and developers to translate speech solutions into production-ready healthcare tools.

Let me introduce...

With Sonia, doctors are successful doctors. We create and deploy AI-enhanced solutions that make doctors’ lives easier, patients’ care better, and healthcare systems more efficient. If you’re an intrinsically motivated self-starter who values impactful work, join us in revolutionizing healthcare.

We’re looking for aMachine Learning Engineer (ASR)to join our AI team. You will be at the forefront of developing the speech recognition systems that power real-world applications used by clinicians every day.

Location:PreferablyHybrid (Luxembourg or Berlin) or Remote (Germany or Luxembourg).

This is what you’ll own

• ASR Model Development:Fine-tune, evaluate, and deploy state-of-the-art models in speech recognition and audio processing (e.g., Whisper, wav2vec).
• Data Curation & Annotation:Collect and curate custom ASR datasets, including data sourcing, annotation pipeline setup, quality control, and alignment/segmentation procedures.
• Audio Pipelines:Build and maintain robust data pipelines and audio preprocessing workflows for clinical environments.
• MLOps Collaboration:Work closely with the MLOps team to ensure continuous training, monitoring, and seamless deployment of models in production.
• Experimentation:Design and conduct experiments to validate new approaches, datasets, and architectures to improve accuracy in noisy or specialized medical settings.
• Cross-Functional Impact:Collaborate with product managers and developers to translate complex speech solutions into production-ready healthcare tools.
