Your Job
Molex is seeking a hands-on Mechanical Design Engineer to design, develop, build, and improve custom manufacturing equipment, tooling, and automation systems. This role will lead projects from concept through commissioning, including mechanical design, fabrication oversight, assembly support, troubleshooting, validation, and continuous improvement of existing equipment.
The ideal candidate has strong machine-building experience and is comfortable working in a manufacturing environment where practical problem-solving, equipment reliability, safety, and innovation are critical. This engineer will collaborate closely with Controls Engineers, Process Engineers, Maintenance, Production, Quality, and external vendors to deliver reliable and cost-effective equipment solutions.
What you will do
- Design custom manufacturing equipment, fixtures, tooling, guarding, and automation systems using 3D CAD software.
- Develop machine concepts, layouts, assemblies, detailed drawings, and bills of materials.
- Perform engineering calculations related to machine structures, mechanisms, motion systems, pneumatics, and power transmission.
- Evaluate design alternatives based on safety, performance, reliability, manufacturability, maintainability, cost, and schedule.
- Lead equipment projects from concept through fabrication, assembly, debugging, qualification, and production release.
- Work directly with internal resources, fabrication shops, machine builders, and suppliers to ensure equipment is built according to design requirements.
- Provide hands-on support during machine assembly, installation, setup, troubleshooting, and startup.
- Create and maintain equipment documentation, including drawings, bills of materials, spare-parts lists, risk assessments, and recommended maintenance information.
- Partner with Controls Engineers to integrate PLCs, HMIs, sensors, safety circuits, servos, robotics, and vision systems into new and existing equipment.
- Ensure mechanical designs support controls architecture, electrical requirements, machine safety, accessibility, and future scalability.
- Participate in commissioning and debugging to resolve mechanical, controls-interface, and process-performance issues.
- Support continuous-improvement , cost-reduction, and obsolescence-mitigation initiatives.
- Manage multiple engineering projects while maintaining scope, schedule, budget, technical documentation, and stakeholder communication.
- Coordinate design reviews, build activities, acceptance testing, training, and handoff to Operations and Maintenance.
- Communicate project risks, progress, decisions, and resource needs clearly to cross-functional teams and leadership.
