Senior Machine Learning Engineer; ASR

Machine Learning Engineer (ASR)

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 a Machine 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:

Preferably hybrid (Luxembourg or Berlin) or remote (Germany or Luxembourg).

• 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.

Must Haves

• Education:
  
  Master's degree in Computer Science or Engineering.
• Experience:
  
  Typically 5-8+ years of experience in ML engineering.
• Technical Proficiency:
  Strong programming skills in Python (working with production code and deploying models in production) and ML frameworks (PyTorch, Tensor Flow or Jax).
• ASR Expertise:
  Direct experience with ASR models (Whisper, wav2vec, …), VAD, alignment and diarisation, and complex speech/audio processing pipelines.
• Deep Learning:
  Extensive experience with transformer-based architectures and deep learning models.
• MLOps Foundation:
  Practical experience with MLOps pipeline components such as Docker, MLflow, W&B, DVC, or Kubernetes.

Nice to Have

• Domain Knowledge:
  Knowledge of multilingual or domain-specific modeling (specifically medical, legal, or other specialized terminologies).
• Scalability:
  Experience with distributed training systems for large-scale model optimization.
• Language
  
  Skills:
  
  Full proficiency in English and German.

• Full ownership of impactful ML components in a fast-growing AI environment.
• A collaborative team that values curiosity, learning, and pragmatic problem-solving.
• Flexible working arrangements (remote or hybrid).
• 30 days of annual vacation.
• Competitive salary depending on experience.
• The chance to work on products that directly shape the future of healthcare.
