Sr. Process Engineer - Liquid Silicon Rubber (LSR)

Role details

Senior Process Engineer – Liquid Silicone Rubber (LSR)

Technimark is looking for a highly experienced Senior Process Engineer – Liquid Silicone Rubber (LSR) to serve as the Subject Matter Expert for our current and future LSR molding operations within our medical business.

This is a hands-on technical leadership role for an engineer who knows LSR processing at a deep level and can take a program from tool and equipment concept through process development, validation, launch, optimization, and stable production.

The right candidate will bring extensive experience with Liquid Injection Molding (LIM), LSR tooling, dosing and material delivery systems, automation, scientific molding, process validation, and statistical process control, while also understanding conventional thermoplastic injection molding.

Job Description 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.
