Our team of Engineering and Technical professionals is immersed in cutting-edge technologies and innovations. LotusWorks is committed to a diverse and inclusive workplace, integral to our people-first approach. 

We are seeking a motivated and mechanically inclined Waste / Ultra-Pure Water (UPW) Operations & Maintenance Technician Intern to support the operation and maintenance of critical water and wastewater systems within a semiconductor or mission-critical facility.

This role provides hands-on experience with advanced UPW generation, distribution, and wastewater treatment systems, while working alongside experienced technicians and engineers in a highly regulated, safety-focused environment.

Responsibilities:

• Support daily operations of UPW generation and distribution systems, including reverse osmosis (RO), electrodeionization (EDI), ion exchange, degasification, UV oxidation, and sub-micron filtration systems under supervision.


• Assist in operating and monitoring wastewater treatment systems, including neutralization systems, pH adjustment, chemical dosing, lift stations, equalization tanks, and biological processes (e.g., MBR/BNR where applicable).


• Perform routine rounds and system readings; record key parameters such as conductivity, resistivity, TOC, pH, flow rates, pressures, and tank levels, and escalate abnormal conditions.


• Assist with preventive and corrective maintenance on mechanical equipment including pumps, valves, filters, membranes, mixers, blowers, and chemical delivery systems.


• Support water quality monitoring and sampling activities to ensure compliance with process requirements and environmental discharge permits.


• Assist with chemical handling and dosing operations (acids, caustics, and treatment chemicals) in accordance with site safety procedures and SDS requirements.


• Support system flushing, regeneration, and sanitization of UPW systems, including resin beds, RO skids, and distribution loops.


• Assist in troubleshooting system issues such as membrane fouling, scaling, flow restrictions, pump failures, and instrumentation inaccuracies.


• Learn and apply safety procedures including lockout/tagout (LOTO), hazardous chemical handling, and confined space entry.


• Support startup and shutdown activities for UPW and wastewater systems, ensuring controlled and compliant operation.


• Assist in maintaining accurate CMMS documentation (e.g., Maximo), including work orders, calibration records, and maintenance logs.


• Observe and support vendor activities such as membrane cleaning, media replacement, and system performance testing.


• Participate in Environmental Health & Safety (EHS) programs, audits, and continuous improvement initiatives focused on safety, compliance, and water conservation.


• Develop an understanding of semiconductor water quality standards, contamination risks, and the critical nature of UPW systems for manufacturing operations.


• Any other duties or responsibilities that may be assigned to you in your role. 

Skills Required:

• Exposure to semiconductor, data center, pharmaceutical, or other mission-critical environments


• Basic knowledge of water/wastewater treatment processes (not required)


• Familiarity with CMMS systems (e.g., Maximo) is a plus


• Enrollment in or recent completion of a technical program (mechanical, environmental, or related field)


• Mechanically inclined with a strong interest in hands-on technical work


• Basic understanding of mechanical systems (pumps, piping, valves, etc.)


• Willingness to learn and work in a fast-paced, mission-critical environment


• Strong attention to detail and commitment to safety

Education / Licenses / Certifications

• High school diploma or equivalent


• Proof of education, licenses, and certifications will be required where applicable.
