• Document test results, deviations, corrective actions, and process observations according to quality requirements.

Minimum Qualifications

• Practical Engineer / Technician in Chemistry, Mechanics, Electronics, or a related technical field.
• 1‒2 years of hands‑on experience in a production, lab, or manufacturing environment (quality, process, or test‑related).
• Strong analytical and problem‑solving skills with a structured, methodical approach.
• Ability to work under pressure in a dynamic production and integration environment.
• Good communication skills and ability to work cross‑functionally with different engineering disciplines.
• Basic working proficiency in English (documentation and communication).

Preferred Experience

• Experience working with multidisciplinary systems, production tools, or semiconductor‑related equipment.
• Previous exposure to cleanroom, ISO‑regulated, or safety‑critical environments.
• Familiarity with laboratory safety, chemical handling, or optical inspection techniques.
• Occasional domestic and international travel, including to the United States, may be required as part of this role.
