Mechanical Design Engineer, Injection Molding

What to Expect

The ideal candidate takes pride in their hands-on work, analytical ability, organizational skills and attention to detail.  They appreciate an environment where superior work is encouraged, noticed and rewarded and where individuals carry tremendous responsibility.  They look forward to learning an incredible amount on the job. This position requires up to 15% travel.

What You’ll Do

• Own plastic injection mold and thermal simulation from initial design concept through tool release
• Optimize injection mold process parameters; fill (time, flow front, weld lines, air traps, shear) and pack/hold (switchover, gate freeze, pack profile, sink, shrinkage)
• Run the loop from gate and runner design through vents, waterlines, hot-spot closure, thermal cycling, mold deflection, and warpage
• Size cooling circuits, model melt behavior, and check the tool for deflection, thermal stress, and fatigue under clamp and injection loads
• Own simulations/analysis of adjacent forming processes; vacuum film thermoforming of viscoelastic polymers, radiant heating (IR emitter layout, zone control, view factors, radiative exchange, optical ray tracing)
• Give product design early DFM input, process-engineering feedback into new and replacement tools, and improve cycle time, yield, and uptime
• Provide supporting design validation analysis (FMEA, FEA, CFD, etc.)
• Participate in on-site construction and commissioning activities, serving as the point of contact for technical inquiries and real-time issue resolution
• Provide technical oversight of tooling suppliers and coordinate project activities and resolve project issues with customers, suppliers, and functional owners
• Provide comprehensive equipment validation documentation, ensuring all specifications met

What You’ll Bring

• Degree in Mechanical Engineering, Materials Science, Polymer/Plastics Engineering, or a related field, or equivalent experience
• Minimum 3 years related experience in a technology-based industry, where automated assembly techniques are utilized (high-volume process experience preferred)
• Trial hands-on and injection molding simulation (Moldflow, SIGMASOFT, or equivalent) across fill, pack, cool, and warp analyses for injection molding
• CFD and heat transfer proficiency (STAR-CCM+, Ansys Fluent, or similar), including conjugate heat transfer; working knowledge of structural and thermo-mechanical CAE (ANSYS or similar) for mold tools
• Strong fundamentals in materials science and polymer rheology, including non-Newtonian flow and viscoelasticity
• Experience with viscoelastic flow solvers (Ansys Polyflow, or equivalent) and constitutive models for polymer melts (K-BKZ, Ogden) is a plus, for thermoforming, blow molding, and related forming processes
• Injection mold tool design using 3D CAD (CATIA preferred)
• Knowledge of materials science and understanding of the chemical properties and behavior of materials, such as PUR/PUA and other thermoplastic polymers
• Excellent organizational skills and meticulous attention to detail; mastery of MS Office suite, Confluence, Jira, Word, Excel, PowerPoint, etc.
• Ability to travel up to 15%
