Job Overview

Marketech International Corporation USA is seeking an experienced, safety-focused Chemical Systems Lead Technician to support and coordinate the installation, operation, maintenance, troubleshooting, startup, and commissioning of chemical distribution and process-support systems for the TSMC project in Phoenix, Arizona.

This is a hands-on working-lead position responsible for performing technical fieldwork while providing daily direction, technical guidance, and task coordination to chemical systems and maintenance technicians. The Lead Technician will help organize field activities, verify that assigned work is completed safely and accurately, monitor system conditions, assist with complex troubleshooting, and communicate project status and technical concerns to supervisors, engineers, contractors, vendors, and customer representatives.

The ideal candidate has direct experience with chemical delivery systems, bulk chemical systems, high-purity piping, pumps, valves, filtration equipment, sensors, instrumentation, controls, or related semiconductor facility infrastructure. The successful candidate must be able to lead by example, maintain strict safety and documentation standards, and support technicians in a fast-paced semiconductor, cleanroom, construction, and maintenance environment.

Key Responsibilities

Team Leadership & Daily Work Coordination

Provide day-to-day technical direction and field support to chemical systems technicians, maintenance technicians, contractors, and assigned project personnel.

Coordinate daily work assignments, priorities, equipment inspections, preventive-maintenance activities, corrective-maintenance activities, and commissioning tasks.

Conduct pre-task planning, shift-start briefings, toolbox talks, system walkdowns, and work-area readiness reviews.

Verify that technicians understand applicable work instructions, standard operating procedures, drawings, safety requirements, and task expectations.

Monitor work progress and help ensure assigned activities are completed safely, accurately, and according to schedule.

Serve as the first point of escalation for routine technical concerns, field coordination issues, equipment abnormalities, and questions from technicians.

Train and mentor technicians on chemical-system operations, maintenance procedures, troubleshooting methods, documentation requirements, and safe work practices.

Promote accountability, teamwork, communication, and consistent compliance with project and customer requirements.

Provide clear updates to supervisors, engineers, project managers, and customer representatives regarding work status, system conditions, delays, risks, and outstanding needs.

Chemical System Operations & Maintenance

Lead and perform the operation, inspection, maintenance, and troubleshooting of semiconductor chemical distribution systems and related process-support equipment.

Support bulk chemical delivery systems, chemical distribution units, pumps, valves, piping, tubing, filtration equipment, flow controls, instrumentation, sensors, alarms, and associated components.

Perform and coordinate preventive maintenance, corrective maintenance, equipment inspections, leak checks, operational verifications, and system condition assessments.

Identify abnormal operating conditions, equipment degradation, leaks, alarms, damaged components, contamination risks, and potential reliability concerns.

Assist with chemical transfers, chemical changeovers, system replenishment, material handling, and related operational activities while maintaining strict safety controls.

Verify that tools, materials, replacement parts, PPE, and supporting documentation are available before work begins.

Support equipment uptime and system reliability by prioritizing maintenance needs and coordinating timely corrective actions.

Maintain clean, safe, and organized work areas in accordance with cleanroom, 5S, chemical-control, and project requirements.

Installation, Startup & Commissioning

Lead and perform equipment installation, startup, commissioning, testing, qualification, operational verification, and turnover activities.

Coordinate field verification of piping, tubing, fittings, pumps, valves, filtration equipment, sensors, instrumentation, electrical components, and chemical-delivery equipment.

Support functional testing, pressure testing, flushing, leak testing, alarm verification, interlock testing, system readiness reviews, and equipment startup.

Review P&IDs, process flow diagrams, equipment drawings, technical specifications, work instructions, checklists, and project requirements.

Identify installation deficiencies, incomplete work, damaged materials, incorrect components, unsafe conditions, and deviations from approved documentation.

Coordinate field troubleshooting and corrective-action activities with engineers, vendors, contractors, technicians, and customer representatives.

Support construction, tool-install, facility expansion, shutdown, system modification, and equipment-turnover activities.

Help ensure punch-list items, open technical issues, and commissioning deficiencies are documented and communicated to the appropriate teams.

Troubleshooting & Technical Support

Lead troubleshooting activities involving chemical systems, mechanical equipment, electrical components, controls, instrumentation, alarms, and process-support systems.

Safely use hand tools, power tools, meters, diagnostic instruments, testing equipment, and approved maintenance tools.

Guide technicians through systematic troubleshooting, inspection, testing, component replacement, and operational-verification activities.

Assist with root-cause analysis by collecting equipment history, operating data, alarm information, technician observations, and maintenance records.

Escalate major equipment failures, chemical leaks, safety concerns, process abnormalities, recurring problems, and urgent maintenance needs.

Work with engineering and supervisory teams to implement corrective actions and verify that systems have been safely returned to service.

Document troubleshooting findings, repairs, testing results, replacement parts, system conditions, and recommended follow-up actions.

Safety, Compliance & Documentation

Enforce compliance with chemical-handling procedures, standard operating procedures, lockout/tagout requirements, PPE requirements, cleanroom protocols, and site-specific safety rules.

Support compliance with hazardous-material requirements, Safety Data Sheet procedures, chemical labeling standards, spill-prevention practices, and emergency-response protocols.

Stop or escalate work when unsafe conditions, unclear instructions, uncontrolled hazards, or procedural deviations are identified.

Participate in incident reviews, safety observations, corrective-action activities, and continuous-improvement initiatives.

Review technician work orders, inspection forms, maintenance records, checklists, testing results, and shift documentation for accuracy and completeness.

Maintain accurate records of completed work, open issues, equipment conditions, preventive-maintenance status, and system deficiencies.

Support audits, inspections, customer reviews, project meetings, and documentation requests as assigned.
