Job Description

About the Role

We are looking for an experienced Plastic Tooling & Injection Moulding Process Engineer to support new product development, tooling industrialization, process validation, and production launch activities.

In this role, you will collaborate closely with PDLM, NPI, Engineering, R&D, tooling suppliers, and manufacturing teams across locations to ensure robust product designs, optimized moulding processes, and successful transfer of validated processes into mass production.

The ideal candidate will have strong hands-on expertise in plastic injection moulding, tooling, scientific moulding, process optimization, and NPI/industrialization, along with strong problem-solving and supplier-management capabilities.

Key Responsibilities

• Lead and collaborate effectively within PDLM project teams, working closely with cross-site teams, vendors, suppliers, and production colleagues.
• Partner with NPI, Engineering, R&D, and tooling suppliers to conduct Early Supplier Involvement (ESI), Design for Manufacturing (DFM), and Design for Manufacturability/Assembly/Testing (DfMAT) evaluations.
• Evaluate new product designs for technical feasibility, manufacturability, tooling requirements, and injection moulding process capability.
• Support the qualification of new tooling suppliers and provide technical guidance during mould trials and process development.
• Establish and optimize machine and process parameters using Scientific Moulding principles.
• Plan and execute Design of Experiments (DOE) to optimize processes and identify critical parameters.
• Support process and tooling validation activities, including IQ, OQ, and PQ, and prepare process documentation, setup sheets, work instructions, and manufacturing standards.
• Troubleshoot tooling and process-related issues from First-Off Trial (FOT) through Start of Production (SOP).
• Conduct process capability studies, SPC, root cause analysis, and corrective actions to achieve quality and process targets.
• Ensure smooth and successful transfer of validated moulding processes into mass production.
• Manage the lifecycle of moulds and tooling, including preventive maintenance, service records, and performance tracking for both in-house and supplier-managed tooling.
• Identify and evaluate new moulding technologies, equipment, and process solutions, and conduct technical feasibility studies.
• Drive project deliverables in line with agreed timelines, quality, cost, and technical requirements.

Required Qualifications & Experience

• Degree or Diploma in Engineering, Manufacturing, Mechanical, Electronics, Polymer, Plastics Technology, or a related discipline.
• Minimum 8 years of relevant experience in plastic tooling and injection moulding process engineering.
• Strong experience in injection moulding process development, optimization, and troubleshooting.
• Hands-on experience in plastic mould design, tooling manufacture, mould trials, and tooling validation.
• Experience supporting NPI, industrialization, product transfer, or production launch projects.
• Strong understanding of Scientific Moulding, DOE, SPC, process capability, and root cause analysis.
• Experience working with and managing external tooling and mould suppliers.
• Knowledge of mould qualification, process validation, and production launch activities.
• Strong understanding of plastic material characteristics and their impact on tooling and moulding processes.
• Experience with CAD and/or mould flow analysis software, such as Moldflow, SolidWorks, NX, or Creo.
• Experience in medical devices, Personal Health, electronics, or other high-precision manufacturing environments is highly preferred.
• Scientific Moulding certification is an added advantage.

Key Competencies

• Strong technical and analytical problem-solving skills.
• Ability to apply statistical and engineering methods to solve complex manufacturing problems.
• Strong understanding of the relationship between part design, tooling design, materials, process parameters, and final product quality.
• Ability to translate product and part requirements into clear technical requirements for relevant subject matter experts.
• Strong project management and execution skills, with the ability to deliver within time, quality, and budget constraints.
• Strong stakeholder management and communication skills.
• Ability to work effectively across global and cross-functional teams.
• Proactive approach to identifying opportunities for process improvement, technology adoption, and manufacturing optimization.

Language Requirements

• English – Fluent
• Mandarin – Fluent; mandatory

Preferred Industry Experience

Experience in one or more of the following environments will be highly valued:

• Medical Devices
• Personal Health / Healthcare
• Consumer Electronics
• High-precision Manufacturing
• Plastic Components Manufacturing
• Injection Moulding / Tooling Industry

How we work together
We believe that we are better together than apart. For our office-based teams, this means working in-person at least 3 days per week. Onsite roles require full-time presence in the company’s facilities. Field roles are most effectively done outside of the company’s main facilities, generally at the customers’ or suppliers’ locations.
