Engineer - Material Scientist (m/f/d)

Lead seed‑wafer reuse process development

• Plan, execute, and analyze experiments across the complete reuse process chain (e.g., CVD, wet chemistry, grinding).
• Demonstrate and continuously improve seed‑wafer reuse performance, yield, and quality.
• Troubleshoot process deviations and implement corrective measures.

Drive material characterization activities

• Apply and develop advanced material characterization methods to identify defects, investigate material degradation, and perform failure analysis.
• Correlate material properties with process parameters to drive evidence‑based improvements.
• Conduct internal laboratory characterization and coordinate external analysis with partner labs.

Collaborate across process and engineering teams

• Work closely with epitaxy, process development, engineering, and operations to improve product performance and address cross‑functional challenges.
• Support optimization of manufacturing processes, workflows, and equipment performance.

Operational and technical support

• Contribute to preventive and corrective maintenance planning with engineering and maintenance teams.
• Act as a technical point of contact for planning equipment and workflows related to seed‑wafer reuse.
• Prepare technical documentation, analysis reports, and recommendations for engineering decisions.

• Ph.D. in Materials Engineering, Materials Science, Physics, Chemistry, Chemical Engineering, or related field
  OR M.Sc. + 3 years’ relevant experience
  OR B.Sc. + 5 years’ experience.
• Proven expertise in defect characterization and material analysis (required).
• Experience in a semiconductor or photovoltaic environment is a plus.
• Hands‑on experience working in laboratories or cleanroom environments (preferred).
• Strong understanding of material science principles; silicon knowledge is a plus.
• Knowledge of epitaxy processes (advantageous).
• Experience with material degradation testing and failure analysis (desired).
• Ability to use statistical and analytical tools (e.g., JMP, Origin).
• Familiarity with CVD, wet chemistry, and wafer‑handling processes (beneficial).
• Fluency in English required.
• German language skills are an advantage.
