Joining us means becoming part of a passionate, international team where your voice is heard, your ideas matter, and your career growth is supported.

Your Challenge:

Our products are key components in semiconductor processing equipment worldwide. To support the development of intelligent vacuum systems, we are looking for an intern who wants to combine hands-on experimentation with data science and machine learning. During your internship, you will investigate gas dynamics in a vacuum process chamber using advanced sensor technologies. You will contribute to the complete development cycle, including experimental planning, data collection, preprocessing, feature engineering, time-series modelling, and model validation.

Your responsibilities will include:

• Become familiar with vacuum technology, gas dynamics, process chambers, and sensor systems.
• Support the setup and execution of experiments in our vacuum test laboratory.
• Plan experiments using a structured Design of Experiments approach.
• Collect and organize multivariate time-series data from different sensor technologies.
• Develop data-preprocessing workflows for synchronization, filtering, segmentation, outlier handling, and data-quality assessment.
• Explore the relationships between sensor signals, gas properties, and process conditions.
• Develop and compare data-driven methods for:
• Feature extraction
• Gas or process-condition classification
• Prediction and regression
• Process monitoring
• Event or anomaly detection
• Validate the developed methods using independent experiments and different operating conditions.
• Document experimental procedures, datasets, modelling methods, results, and limitations.
• Present your findings and potential next steps to engineers and researchers.

Your Competencies:

• Currently pursuing an MSc degree in data science, machine learning, physics, mathematics, mechanical engineering, electrical engineering, chemical engineering, control engineering, mechatronics, or a related field.
• knowledge of data analysis, statistics, signal processing, or machine learning.
• Programming experience in or MATLAB.
• Interest in combining experimental work with data-driven modelling.
• Willingness to work hands-on with vacuum equipment, sensors, and data-acquisition systems.
• Systematic thinking and enthusiasm for developing innovative technical solutions.
• Ability to learn independently and collaborate in a multidisciplinary R&D environment.
• written and spoken English.

Additional experience is a plus:

• Experience with time-series data, signal processing, or sensor-data analytics.
• Familiarity with scikit-learn, PyTorch, TensorFlow, MATLAB, or similar tools.
• Experience with Design of Experiments or laboratory measurements.
• Knowledge of feature engineering, model validation, or uncertainty estimation.
• Interest in vacuum technology, gas sensing, process control, or semiconductor manufacturing.

What you will learn:

• Hands-on experience with vacuum systems and advanced sensor technologies.
• Experimental design and systematic data collection.
• Preprocessing and analysis of large multichannel sensor datasets.
• Time-series machine learning for real physical systems.
• Validation of data-driven models through laboratory experiments.
• Application knowledge in gas sensing and semiconductor equipment.
