Full Job Description
Sr. Tooling Engineer
IRP MED is seeking a highly motivated Senior Tooling 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.
Key Responsibilities
Optimize mold designs for manufacturability, cycle time reduction, part quality, venting, gating, and automation compatibility.
Collaborate with product engineering, manufacturing, quality, and process engineering teams to ensure tooling meets functional and production requirements.
Develop and maintain tooling documentation, revision control, BOMs, maintenance standards, and engineering change records.
Generate mold design concepts (Solidworks) to support new products, or re-design tooling for existing products to improve efficiency.
Lead tooling troubleshooting activities related to flash, short shots, air entrapment, knit lines, dimensional variation, and cosmetic defects.
Coordinate with external tool shops, suppliers, and internal machining teams during tool fabrication and qualification.
Recommend improvements for tooling reliability, preventive maintenance, and process capability.
Support continuous improvement initiatives related to tooling performance, scrap reduction, and manufacturing efficiency.
Create detailed 3D CAD models, mold layouts, and manufacturing drawings.
Support mold flow analysis, tolerance stack-ups, shrinkage calculations, and DFM reviews.
Participate in mold trials, process validations, FAI activities, and production launches.
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%
Required Qualifications
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.

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.
Preferred Qualifications
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.
