Intern/Working Student - Machine Learning

Omnisent is pioneering scalable acoustic sensing powered by AI — transforming audio into real-time intelligence.

We build hardware + software tailored for acoustic data, designed to extract insights from complex acoustic signals. Our proprietary ultra-low-power sonic devices capture and process acoustic signals in real-time, training what we call a Large Acoustic Model (LAM) — our foundation model built to decode the rich, messy, and untapped world of non-speech audio.

We’re starting with the manufacturing industry, applying our tech to compressed air systems — one of the most overlooked sources of energy waste. From there, we’re expanding into energy, defense, space, and smart cities — sectors where sound is the next frontier.

Please note: This is an on-site position in Munich . Applicants must have a valid EU work permit and be available to work from our Munich office during the semester.

Aufgaben

• Tune hyperparameters and optimize classification pipelines for classical Machine Learning (ML) models and Deep Neural Networks (DNNs)
• Extract and engineer features from raw acoustic signals (e.g. FFTs, spectral and time-domain features)
• Compare models using suitable quantitative metrics and interpretability methods (i.e. XAI tools)
• Design and test neural network architectures
• Analyze model behavior on unseen or noisy data, and test generalization
• Maintain code quality through modular design, logging, and documentation
• Prototype lightweight model deployment (e.g., exporting models, running inference APIs)
• Create visualizations to understand feature behavior, model decisions, and inference quality

Qualifikation

Basic Requirements:

• Currently enrolled in a Master’s program in Computer Science, Machine Learning, Data Science, or related field
• Strong Python skills, including experience with: numpy, scikit-learn, matplotlib, pytorch
• Experience training and testing ML and DL models
• Experience using Git, writing clean, modular, and reproducible code
• Solid understanding of model evaluation and basic interpretability (confusion matrices, feature importance, Grad-CAM, etc.)
• Curious, self-driven, and structured in your approach
• Fluent in English

Preferred Skills:

• Experience working with acoustic data, time-series, or Fourier/spectral representations
• Familiarity with feature extraction for audio: time-domain (e.g., peak analysis, RMS) and frequency-domain (e.g., FFTs, spectral features)
• Experience with model interpretability (such as GradCam, Shap, LIME, feature importance, etc.)
• Experience with model deployment for real-time applications and/or cloud services such as Azure

Join us in redefining how the world listens, understands, and responds through intelligent acoustic sensing.
