About The Position

Process Technician III is a senior technical resource responsible for complex injection molding setup, optimization, troubleshooting, and technical leadership. This role mentors other technicians, drives process improvements, and may coordinate technical priorities or cover lead responsibilities when assigned. It is a hands-on, non-exempt position and does not replace formal supervisory accountability. Successful Level III technicians are trusted technical leaders who resolve the toughest processing problems, prevent repeat failures, develop other technicians, and improve safety, quality, uptime, cycle performance, and scrap results.

Requirements

Typically, five or more years of progressive injection molding Process Technician experience, including advanced setup, processing, and troubleshooting responsibility.
Demonstrated mastery of injection molding fundamentals, process optimization, molding defects, pressure and velocity control, transfer, back pressure, decompression, clamp requirements, and hot-runner systems.
Advanced experience with industrial robots, end-of-arm tooling, auxiliary equipment, machine controls, and safe mold-change practices.
Proven ability to lead complex technical problem-solving, perform root-cause analysis, and communicate clear recovery or improvement plans.
Experience training or mentoring technicians and working effectively across Production, Maintenance, Quality, Tooling, and Engineering.
Strong computer, documentation, and data-analysis skills.
Ability to demonstrate required Level III competencies through Schaefer’s skills assessment and practical evaluation.
Mechanical and process troubleshooting
Safety and quality discipline
Clear shift-to-shift communication
Teamwork and knowledge sharing

Create, modify, validate, and document machine and robot programs within authorized change-control requirements.
Guide technicians through difficult startups and troubleshooting events while keeping production leadership informed of risk, downtime, and recovery plans.
Mentor and train Process Technician I and II employees; reinforce standard work and help evaluate practical skills and training needs.
Partner with Production, Quality, Maintenance, Tooling, Engineering, and Safety on root-cause analysis and corrective actions.
Identify and implement improvements that increase output, reduce cycle time and scrap, improve changeover performance, and prevent repeat failures.
When assigned, help prioritize technician calls, coordinate shift technical coverage, support handoffs, and provide lead coverage without independently administering discipline or other formal supervisory actions.
Support trials, new mold launches, process validation, documentation updates, and transfer of technical knowledge to production teams.
Monitor injection molding machines and respond promptly to process-related issues to reduce downtime and scrap.
Start up and adjust machines to support safe, efficient production and consistent product quality.
Perform mold changes, insert changes, version changes, and date-code verification according to established procedures.
Set up and operate auxiliary equipment used in the injection molding process.
Set up, reference, and operate robotic material-handling equipment appropriate to the assigned level.
Complete first-piece verification and required production, mold-change, and shift documentation accurately.
Inspect in-process and finished product; identify defects and take or escalate corrective action.
Assist Maintenance with troubleshooting and repairs involving machines, molds, heaters, thermocouples, and auxiliary equipment.
Follow lockout/tagout, crane and sling inspection, machine-guarding, PPE, and all other safety requirements.
Maintain a clean, organized work area and communicate production or quality concerns during shift handoffs.
Perform other duties and provide overtime or shift coverage as assigned based on business needs.
