Precision Mold & Fixture Engineer

Amphenol CMT - Critical Medical Technologies; Tijuana; On-site; MXN 420,000 - 660,000; Full time

Job summary

The Mold & Fixture Designer at Amphenol CMT - Critical Medical Technologies will design precision tooling, including plastic injection molds and LSR molds, plus production fixtures. You will ensure designs meet quality, manufacturability, and efficiency standards to support new products and ramp-ups.

The role requires 4–6 years of mold design experience, strong CAD skills (SolidWorks, NX, CATIA or Creo), and familiarity with GD&T and mold machining.

Qualifications

• Associate or bachelor’s degree in mechanical engineering, Tool Design, or related discipline.
• 4–6 years of experience in plastic injection and/or silicone mold design.
• Strong understanding of mold construction, venting, and gating design.
• Familiarity with LSR tooling, including cold runner systems and temperature control design.
• Experience designing production fixtures (for assembly, measurement, and testing).
• Skilled in 3D CAD modeling and detailing (SolidWorks, NX, CATIA, Creo, or equivalent).
• Knowledge of GD&T, tolerancing, and mold machining processes.
• Ability to read, write, speak, and understand English.

Responsibilities

• Design plastic injection molds, LSR (silicone) injection molds, and precision assembly/test fixtures using advanced 3D CAD tools (e.g., SolidWorks, Siemens NX, CATIA, or similar).
• Develop detailed 2D drawings and 3D models, including parting lines, shut-offs, cooling channels, venting, ejector systems, gating, and runner layouts.
• Incorporate Design for Manufacturability (DFM) and Design for Assembly (DFA) principles into all designs.
• Perform or review mold flow analyses (e.g., Moldflow, Moldex3D) to predict part filling, cooling, and warpage, and implement design improvements accordingly.
• Design fixtures for assembly, inspection, and testing, ensuring ergonomic, repeatable, and accurate operation.
• Create and maintain Bills of Materials (BOMs), drawings, and revision-controlled design files.
• Collaborate with mold makers, tool shops, and suppliers during tool fabrication and trials.
• Support tooling trials, validation builds, and production ramp-ups, providing design insights and troubleshooting assistance.
• Participate in FMEA reviews, lead design reviews, and lessons-learned sessions to drive continuous improvement.
• Maintain compliance with company, safety, and quality standards (e.g., ISO 9001, IATF 16949, ISO 13485 if applicable).
• Stay current with tooling technologies, materials, and manufacturing methods, including hot runners, cold runners, and LSR injection systems.
• Directly support product management in customer discussions. Model proposed tool split geometry and customize models for preferred embodiment.
