Overview:
This role is responsible for establishing, maintaining, and improving wet cleaning processes in a cleanroom environment to achieve vacuum-cleanliness and surface-cleanliness levels for parts used in assembly. This role owns the cleanliness concept across wet line operations, ensuring on-time delivery, product quality, and compliance with stringent cleanliness standards through robust process design, monitoring, documentation, and structured problem-solving (including SPC).
Job Description:
- Provide engineering support for wet line and optics bonding processes to maintain output, OTD, and product quality.
- Develop, qualify, and sustain cleaning and handling processes (visual, UV, particle, RGA verification where applicable).
- Interpret semiconductor equipment cleanliness requirements and convert them into practical process flows, parameters, and work instructions.
- Define environmental and equipment requirements (cleanroom class, approved chemistries, fixtures, part orientation, handling rules).
- Establish and manage cleanliness monitoring plans (bath life, filtration, DI water quality, environmental monitoring, in-process audits, product cleanliness checks).
- Drive preventive contamination controls (coolants, lubricants, tool/fixture cleanliness, storage, transport, surface protection).
- Collaborate with design engineering to ensure compatibility of geometries, materials, and joining methods with cleaning and inspection requirements.
- Translate cleanliness requirements into supplier specifications; support supplier selection, audits, and corrective actions.
- Support cleanliness qualification of suppliers and process qualification for operations and facilities.
- Ensure compliance with QMS and AS9100 documentation requirements (SOPs, control plans, checklists, maintenance, calibration, test procedures).
- Lead cleanliness and process improvement initiatives across manufacturing flow.
- Perform Statistical Process Control (SPC) and statistical analysis to monitor and improve process capability.
- Apply structured problem-solving methodologies (8D, DOE, RCCA).
- Validate equipment and processes for cleanliness and operational compliance.
- Support tooling, jigs, fixtures, and gauges design for cleanroom operations.
- Drive root cause investigations and CAPA for cleanliness or quality deviations.
- Train operators and technicians on cleanroom behaviour and cleanliness-critical process steps.
- Champion a cleanliness-first culture and escalate risks or non-conformances.
Job Requirements:
- Master's degree in Chemistry, Optical, Materials, Physics, or Bachelor's degree with minimum 3 years relevant experience.
- 3+ years experience in semiconductor, optics, precision manufacturing, or high-purity cleanroom environment.
- Strong understanding of contamination control and ISO Class 6 (or higher) cleanroom standards.
- Experience in SPC, DOE, 8D, RCCA, and process control implementation.
- Familiar with reverse osmosis and ion exchange water treatment technology (advantageous).
- Experience working within ISO 9001 / AS9100 certified QMS.
- Knowledge of NEA chemical safety requirements.
- Experience in optics bonding is advantageous.
- Competent in documentation for optical / laser product build and test.
- Proficient in MS Office.
- Strong analytical mindset with ability to train and coach operators.
