About The Role

As a MOCVD Technician , you will support the operation, maintenance, and reliability of epitaxy systems used in semiconductor manufacturing.

This is a hands-on technical role focused on maintaining complex gas, vacuum, and reactor systems that enable the production of high-performance semiconductor laser materials. You will work closely with engineering and production teams to ensure safe, stable, and efficient operation of critical manufacturing equipment.

Key Responsibilities

Equipment Maintenance & Reliability
Perform preventive and corrective maintenance on MOCVD reactors and associated infrastructure (gas supply, abatement, vacuum systems)
Support maintenance of vacuum pumps and gas systems
Troubleshooting & Repairs
Troubleshoot mechanical, electrical, and process-related issues to ensure system uptime
Replace and maintain components such as filters, piping, and gas handling systems
Safety & Operations
Safely handle and exchange pressurized gas cylinders , following strict safety protocols
Monitoring & Process Stability
Monitor and interpret system data and logs for fault diagnosis (e.g. SPC)
Ensure equipment availability and process stability in a production environment
Document maintenance and service activities in line with quality standards
Testing & Systems Support
Support the setup and maintenance of measurement and testing systems (e.g. wafer characterisation or similar diagnostic equipment)
Work with control systems (PLC-based) to identify and resolve operational issues

Qualifications

Completed technical training, apprenticeship, or equivalent in Mechatronics, Electronics, Automation, Industrial Mechanics , or a related field
~3+ years of hands-on technical experience (or strong apprenticeship background)
Experience in semiconductor manufacturing, chemical processing, gas systems, vacuum systems, or similar industrial environments is a plus, but not required.

Skills & Other Requirements

Understanding of basic physics and technical systems (pressure, gas flow, electrical fundamentals)
Ability to read and interpret electrical schematics and technical diagrams
Experience with maintenance and troubleshooting of industrial equipment
Strong awareness of safety protocols , particularly in regulated or hazardous environments
Ability to work in a cleanroom and safety-critical environment , including use of respiratory protection equipment (training provided)
German working proficiency required and English language skills is a plus

Quality and Environmental Responsibilities

Depending on location, this position may be responsible for the execution and maintenance of the ISO 9000, 9001, 14001 and/or other applicable standards that may apply to the relevant roles and responsibilities within the Quality Management System and Environmental Management System.
