EHS Lead II​/Site EHS Leader

The EHS Lead II / Site EHS Leader will provide practical, visible, and technically strong EHS leadership for three ASM Arizona facilities: two in Chandler and one in Phoenix. This role partners closely with facilities, engineering, operations, product safety, contractors, and site leadership to maintain a safe, compliant, and continuously improving workplace in a semiconductor equipment environment. The role has broad ownership for EHS program execution, regulatory compliance, risk reduction, emergency preparedness, and environmental programs covering air, water, wastewater, stormwater, hazardous materials, and waste management.

While we are recognized as industry leaders today, we are committed to continuous improvement and recognize the ongoing opportunities for further advancement. This role provides both significant challenges and rewards, offering measurable progress and achievements on both a daily and long-term basis.

• Lead site EHS execution for three ASM Arizona facilities, ensuring programs are practical, consistent, and aligned with corporate requirements and local operations.
• Serve as a trusted EHS advisor to site leadership, engineering, facilities, operations, product safety, contractors, and employees.
• Translate requirements into action by developing clear procedures, work instructions, training materials, inspections, and field controls.
• Influence without direct authority and build strong working relationships with leaders, employees, contractors, customers, and external stakeholders.
• Use data to improve performance by analyzing EHS metrics, identifying trends, and leading corrective and preventive actions.
• Support safe work in cleanroom and lab environments around semiconductor equipment, process modules, hazardous gas and chemical systems, facilities utilities, and supporting infrastructure.
• Lead risk assessments and field reviews for equipment installation, deinstallation, maintenance, non-routine work, contractor activity, and process changes.
• Maintain strong safety programs including chemical safety, hazardous energy control, electrical safety, contractor safety, ergonomics, emergency response, incident reporting, and employee training.
• Provide industrial hygiene support including exposure assessment planning, monitoring coordination, ventilation review, chemical control guidance, and follow-up actions.
• Oversee incident and health case reporting in line with regulatory and company requirements, and ensure investigations identify practical corrective actions.
• Air compliance: support air permit applicability reviews, emissions tracking, control requirements, recordkeeping, reporting, and change reviews for tools, processes, abatement systems, and facilities equipment.
• Water and wastewater: support wastewater discharge compliance, pretreatment requirements, sampling coordination, pH or treatment system controls, water use reduction efforts, and required records or reports.
• Stormwater: maintain stormwater pollution prevention controls, inspections, training, corrective actions, and documentation for outdoor activities, chemical storage, waste storage, and contractor work.
• Hazardous and universal waste: manage waste profiles, accumulation areas, labeling, inspections, manifests, vendor coordination, employee training, and disposal records.
• Hazardous materials: support chemical inventory, Safety Data Sheet management, labeling, storage compatibility, permit conditions, and emergency planning information.
• Sustainability and reduction efforts: partner with site teams to reduce waste, emissions, water use, and compliance risk while supporting business continuity and operational needs.
• Maintain compliance with applicable regulations, permits, corporate standards, and management systems including ISO 14001 and ISO 45001 where applicable.
• Plan and conduct audits and inspections to verify program effectiveness, identify gaps, and drive timely closure of corrective actions.
• Develop and deliver training for local and global programs, and evaluate whether training is effective in the field.
• Support emergency preparedness and resilience including emergency response plans, drills, business resilience planning, and disaster recovery activities across the Chandler and Phoenix locations.
• Participate in management of change reviews so EHS requirements are addressed before new equipment, chemicals, facility modifications, or process changes are implemented.
• Respond to emergencies or urgent EHS needs including occasional off‑hours support, as required.

• Bachelor’s degree in occupational health and safety, environmental science, engineering, chemical engineering, chemistry, industrial engineering, or a related technical field.
• 5+ years of progressive experience leading EHS programs in semiconductor, high‑tech manufacturing, research and development, equipment design, or similar technical operations.
• Working knowledge of environmental compliance programs, including air emissions,…
