Senior Tool Design Engineer
About The Position
IRP MED is seeking a highly motivated Senior Tool Design Engineer to support the design, development, and optimization of tooling for Liquid Silicone Rubber (LSR) molded components. This role is responsible for creating precision mold designs, supporting manufacturing and validation activities, and collaborating cross-functionally to ensure high-quality, cost-effective production solutions for medical applications. The ideal candidate has strong experience in injection mold design, understands LSR processing requirements, and thrives in a fast-paced manufacturing environment focused on innovation, precision, and continuous improvement.
Requirements
- Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering, Tool Engineering, or related field.
- 8+ years of experience in injection mold design, preferably with Liquid Silicone Rubber (LSR) or elastomeric materials.
- Proficiency with CAD software such as SolidWorks, or AutoCAD.
- Strong understanding of injection molding principles, mold construction, hot runner systems, venting, cooling, and automation.
- Experience interpreting GD&T and engineering drawings.
- Knowledge of mold manufacturing processes including CNC machining, EDM, polishing, and tool assembly.
- Strong analytical and problem-solving skills.
- Excellent communication and project coordination abilities.
Nice To Haves
- Proficient at mold design using Solid-Works (3D Design, tooling for molding).
- Experience with medical-grade or high-precision LSR components.
- Experience with multi-cavity, cold deck, or valve gate LSR tooling systems.
- Understanding of validation protocols (IQ/OQ/PQ).
- Knowledge of cleanroom manufacturing environments.
- Lean manufacturing or Six Sigma experience.
Responsibilities
- Generate mold design concepts (Solidworks) to support new products, or re-design tooling for existing products to improve efficiency.
- Create detailed 3D CAD models, mold layouts, and manufacturing drawings.
- Collaborate with product engineering, manufacturing, quality, and process engineering teams to ensure tooling meets functional and production requirements.
- Optimize mold designs for manufacturability, cycle time reduction, part quality, venting, gating, and automation compatibility.
- Support mold flow analysis, tolerance stack-ups, shrinkage calculations, and DFM reviews.
- Coordinate with external tool shops, suppliers, and internal machining teams during tool fabrication and qualification.
- Lead tooling troubleshooting activities related to flash, short shots, air entrapment, knit lines, dimensional variation, and cosmetic defects.
- Participate in mold trials, process validations, FAI activities, and production launches.
- Develop and maintain tooling documentation, revision control, BOMs, maintenance standards, and engineering change records.
- Recommend improvements for tooling reliability, preventive maintenance, and process capability.
- Support continuous improvement initiatives related to tooling performance, scrap reduction, and manufacturing efficiency.
- Ensure compliance with customer specifications, ISO standards, safety requirements, and industry regulations.
- Ability to travel to Tooling vendors as needed, travel time up to 10%
