• Contribute to the development of AI-powered solutions leveraging modern techniques such as:
  • Generative AI / Agentic AI workflows
  • LLM-assisted analytics
• Build and maintain reproducible ML pipelines using tools such as Databricks, MLflow, DVC, and Azure DevOps.
• Collaborate closely with production engineers, process experts, and data engineers to translate manufacturing challenges into data-driven solutions.
• Perform feature engineering, model validation, and statistical analysis on manufacturing and reliability datasets.
• Support integration of AI solutions into production workflows and ensure scalability and robustness.
• Participate in experiment design and validation of predictive models.
• Contribute to documentation, version control, and CI/CD best practices within the team.

Required Skills and Qualifications:

• Experience in AI, machine learning, and deep learning, including production implementation.
• Proficiency in programming languages such as Python.
• Experience with ML libraries such as (Scikit-learn, PyTorch or TensorFlow, XGBoost or similar frameworks)
• Experience with data visualization tools like JMP, Power BI, or Python libraries.
• Experience working with data pipelines and version control tools (e.g., Git)
• Familiarity with modern ML lifecycle tools such as (MLflow, Databricks, DVC, Azure DevOps) or similar CI/CD platforms.
• Understanding of version control systems like Git.
• Understanding of:
  • Data preprocessing and feature engineering
  • Model evaluation and validation techniques
• Ability to work independently while collaborating in a cross-functional production environment.
• Strong communication skills to explain technical concepts to non-technical stakeholders.
• Fluency in English is required; German language skills are an advantage but not essential.

Preferred Skills and Qualifications:

• Knowledge or experience in:
  • Semiconductor manufacturing
  • VCSEL or Edge Emitter lasers
  • Photonics and applied physics
• Familiarity with Generative AI concepts and LLM-based applications.
• Experience with SQL and structured data environments.
• Basic understanding of cloud platforms (Azure preferred).
• Knowledge of experiment tracking, reproducibility, and ML pipeline automation.
• Understanding of statistical analysis and experimental design.

Education and Experience:

• Bachelor's or Master's degree in a relevant field (e.g. Computer Science, Data Science, Physics, Material Science, or related disciplines) with 1-3 years of experience in data science or a related role with a focus on ML and DL in a production environment.
• Or aPhD in a relevant field (e.g., Computer Science, Physics, Photonics, Material Science, or related disciplines) will be considered equivalent to professional experience.
