Chemical Process Engineer – Precision Cleaning

We are seeking a hands-on Chemical Process Engineer – Precision Cleaning to support and maintain a high-purity precision cleaning operation serving the semiconductor manufacturing industry.

This position will be responsible for technical ownership, control, troubleshooting, and continuous improvement of chemical cleaning processes used on precision-manufactured components. The ideal candidate will have a strong understanding of chemical process control, contamination prevention, material compatibility, DI water systems, cleanroom operations, and process qualifications.

This is a hands-on manufacturing position requiring regular interaction with production, quality, maintenance, engineering, and customer requirements.

Key Responsibilities

• Provide technical ownership and day-to-day support of multi-stage precision chemical cleaning processes.
• Monitor and control bath chemistry, including concentration, pH, temperature, contamination levels, bath life, and replenishment requirements.
• Establish and maintain operating parameters, control limits, sampling frequencies, and reaction plans for chemical processes.
• Develop methods for determining chemical bath life and appropriate change-out intervals based on process performance and analytical data.
• Monitor DI water and rinse-system performance, including resistivity/conductivity, filtration, water quality, and rinse effectiveness.
• Troubleshoot chemical cleaning, rinsing, drying, staining, corrosion, residue, particle, and contamination issues.
• Analyze cleanliness results and identify trends related to particulate, ionic, organic, and metallic contamination.
• Lead root-cause investigations and corrective actions for cleaning-process failures and customer concerns.
• Develop and maintain process specifications, work instructions, chemical control plans, inspection requirements, and other controlled documentation.
• Support customer process qualifications, audits, technical reviews, and continuous-improvement initiatives.
• Support cleanroom contamination-control practices and continuous improvement of cleanroom processes.
• Provide technical training and guidance to operators responsible for chemical cleaning processes.
• Work with EHS personnel to ensure safe chemical handling, storage, PPE, ventilation, spill response, and waste-management practices.

Minimum Qualifications

• Bachelor's degree in Chemical Engineering or Chemistry**.**
• Minimum 3 years of experience supporting chemical processing, precision cleaning, surface treatment, semiconductor manufacturing, aerospace manufacturing, medical devices, or another high-purity manufacturing environment.
• Strong understanding of chemical concentration, pH, temperature control, contamination, bath life, and process stability.
• Experience developing, maintaining, or improving controlled manufacturing processes.
• Ability to analyze manufacturing and laboratory data and make data-driven process decisions.
• Strong technical writing and documentation skills.
• Ability and willingness to work directly on the manufacturing floor and within cleanroom environments.

Preferred Qualifications

• Experience in semiconductor precision cleaning or semiconductor equipment manufacturing.
• Experience supporting customer-specific semiconductor cleanliness requirements.
• Knowledge of high-purity DI water systems and rinse processes.
• Experience with wet-bench or multi-tank chemical cleaning systems.
• Knowledge of cleanroom contamination-control practices.
• Experience with chemical processing of aluminum components.
• Experience with acid-based cleaning and passivation processes.
• Experience with process qualification and validation in a highly controlled manufacturing environment.
• Experience working within ISO 9001, AS9100, semiconductor, or comparable quality-management systems.
