Description

Job Duties and Responsibilities include:

• Lead LSR/LIM process development, applying scientific molding principles, Design of Experiments (DOE), statistical analysis, and structured troubleshooting to establish robust processing windows.
• Provide technical expertise related to two-component LSR material delivery and metering, mixing, cold-runner systems, mold temperature management, cure behavior, tooling, automation, demolding, and process optimization.
• Lead and support IQ/OQ/PQ validation activities for LSR molding equipment, tooling, automation, and manufacturing processes used for medical components.
• Participate in LSR mold design reviews, equipment specification and selection, capital appropriation requests, and the installation and qualification of new manufacturing systems.
• Lead tooling and process activities for new product introductions from design and mold build through sampling, validation, commercialization, and production launch.
• Partner closely with Quality, R&D, Manufacturing, Tooling, Automation and Project Management to successfully industrialize new programs.
• Use cavity pressure and other process-monitoring technologies such as RJG eDART/CoPilot and Kistler ComoNeo/CoMo systems to establish and maintain process control.
• Troubleshoot complex interactions among material, machine, mold, temperature control, automation, and part design.
• Lead continuous improvement initiatives focused on cycle time, scrap reduction, process capability, uptime, repeatability, and overall manufacturing performance.
• Develop technical standards and training materials and provide mentoring, coaching, and technical leadership to Process Engineers, technicians, setup personnel, and other manufacturing associates.
• Interface directly with customers, suppliers, equipment manufacturers, and tooling partners as the technical processing lead for assigned LSR programs.

Desired Experience

• Ideally 10-15+ years of hands-on process engineering experience, including significant experience with Liquid Silicone Rubber/Liquid Injection Molding (LSR/LIM).
• Demonstrated experience developing, optimizing, troubleshooting, and launching LSR molding processes, including metering/mixing and dosing systems, tooling, cold-runner technology, thermal management, curing behavior, automation, and part handling.
• Demonstrated experience conducting or supporting IQ/OQ/PQ process and equipment qualification.
• Advanced understanding of Scientific Molding, DOE methodology, systematic processing, statistical techniques, root-cause analysis, and structured troubleshooting.
• Experience with conventional thermoplastic injection molding processes, machines, tooling, and materials in addition to LSR.
• Strong project-management, technical documentation, communication, and customer-facing skills.

Preferred Experience:

• Plastics Engineering, Polymer Engineering, Mechanical Engineering, or related technical degree
• RJG Master Molder II certification
• AIM Institute Plastics Technology & Engineering (PTE), Molding 3, or comparable advanced plastic processing education
• Experience with RJG eDART/CoPilot, Kistler ComoNeo/CoMo, or comparable cavity-pressure and process-monitoring technology

Why Technimark:

This is an opportunity for an experienced LSR engineer to have an impact well beyond day-to-day processing. We're looking for someone who can become the person the organization turns to when the question is: "How should we design, validate, launch, and optimize this LSR process?"

You'll influence equipment and tooling decisions, process-development methodology, validation strategy, manufacturing standards, technical training, troubleshooting practices, and future LSR capabilities.

If you've built your career around LSR/LIM processing, enjoy solving difficult molding problems, and want the opportunity to help develop and expand a sophisticated LSR manufacturing capability, we'd like to talk.
