About the role

Own the Equipment. Shape the Process. Build What’s Next.

Are you a hands-on plastics process engineer with deep thermoforming expertise who thrives on solving complex manufacturing challenges?

Do you know your way around equipment, tooling, materials, and process optimization—and enjoy being the person who steps in, troubleshoots issues, and makes the process better? If you’re energized by owning the process from concept through production and turning ideas into stable, repeatable, high-performing manufacturing systems, this is the kind of role where your expertise directly drives results.

We’re looking for a Process Engineer or Senior Process Engineer to lead large-scale, complex, and highly visible thermoforming initiatives. In this role, you’ll serve as the technical owner of process capability and equipment performance, leading projects across the full product lifecycle—from material selection and tooling development to prototyping, validation, scale-up, and full production launch.

This is a high-impact opportunity for an engineer who wants to improve equipment performance, increase process reliability, reduce variation, and drive continuous improvement on the plant floor.

What You’ll Own

  • Lead thermoforming process development and optimization
  • Own equipment performance, process capability, and troubleshooting
  • Partner with tooling, operations, and quality teams to improve manufacturability
  • Drive prototype-to-production scale-up
  • Improve cycle times, scrap reduction, yield, and repeatability
  • Support new product launches and process validation
  • Lead continuous improvement and manufacturing excellence initiatives

What Makes This Role Exciting

  • High visibility across engineering and operations
  • Direct ownership of equipment and process outcomes
  • Opportunity to influence how products are built at scale
  • Hands-on work where your technical decisions matter immediately
  • Strong focus on innovation and process improvement
