• Perform hands-on technical work such as:

  • Drilling, tapping, mounting and fastening of precision parts

  • Cable routing, labeling and documentation

  • Leak checks and basic vacuum work

  • Visual inspections, functional checks and fault isolation

• Support system integration, testing, and commissioning

• Troubleshoot and fix practical hardware issues:

  • Loose connections, misalignments, mechanical tolerances

  • Wiring errors, damaged components, assembly mistakes

• Perform preventive maintenance and basic repairs

• Maintain a clean, safe and well-organized lab environment

• Document work in a clear, technical and reproducible manner

Required skills:

• Completed vocational training (Ausbildung) as Mechatronics Technician, Electronics Technician, Precision Mechanician or a comparable technical trade

• Minimum 3–5 years of hands-on experience with complex, high-precision systems in industry, high-tech manufacturing, or R&D environments

• Strong practical skills in:

  • Mechanical assembly of precision systems

  • Handling tools, fixtures and workshop equipment

  • Reading and executing technical drawings and work instructions

• Structured, reliable and safety-conscious working style

• Ability to work independently and switch between multiple tasks and teams

• Very good German skills (C1/C2 level) and comfortable working in an English-speaking technical environment

Nice-to-have:

• Experience in high-tech or R&D environments, e.g.:

  • Research laboratories

  • Cleanrooms

  • Semiconductor, vacuum, cryogenic or optics labs

• Field service or maintenance background

• Experience directly supporting engineers and scientists

• Basic understanding of optics, lasers or cryogenics

• Genuine interest in advanced hardware and quantum technologies
