Job description

Senior Manufacturing Engineer
Plastic Injection Molding | Medical Device Manufacturing
Location: Charlottesville, VA 22911
Relocation assistance is available for qualified candidates.
 
This is NOT a general manufacturing engineering position.
 
We're seeking a Senior Manufacturing Engineer with hands-on expertise in plastic injection molding within a regulated manufacturing environment (medical device strongly preferred).
 
If your background is primarily automotive, aerospace, machining, assembly, or general manufacturing without injection molding ownership, this role is likely not the right fit.
 
YOU'LL BE RESPONSIBLE FOR:

  • Leading plastic injection molding process development and optimization
  • Driving automation, robotics, and manufacturing process improvements
  • Supporting new product introductions (NPI), tooling validation, and process validation
  • Troubleshooting molding defects and implementing corrective actions
  • Leading Lean Manufacturing and continuous improvement initiatives
  • Partnering with Engineering, Quality, Operations, and suppliers to improve manufacturing performance
  • Ensuring manufacturing processes comply with quality and regulatory requirements

 
REQUIRED QUALIFICATIONS:

  • At least 5+ years of Manufacturing Engineering experience supporting plastic injection molding
  • Hands-on experience with: Scientific Molding | Mold Tooling and Qualification | Injection Molding Process Development | Process Optimization | Automation and Manufacturing Improvements
  • Experience working in a regulated manufacturing environment, preferably medical device manufacturing
  • Bachelor's degree in Mechanical Engineering, Manufacturing Engineering, Plastics Engineering, Industrial Engineering, or a related technical discipline

Preferred Experience:

  • Medical device manufacturing
  • FDA and/or ISO 13485 regulated environments
  • IQ/OQ/PQ process validation
  • PFMEA, Control Plans, DOE, and SPC
  • Robotics, vision systems, and automated manufacturing equipment

 
ADDITIONAL INFORMATION:

  • Work Authorization: Applicants must be legally authorized to work in the United States at the time of application. This employer is unable to sponsor or transfer employment visas at this time
  • If you've built your career improving plastic injection molding processes in a regulated manufacturing environment and enjoy solving complex manufacturing challenges through automation, regulatory compliance, and continuous improvement, we'd love to hear from you

 
Equal Opportunity Employer: We are an Equal Opportunity Employer and are committed to creating an inclusive workplace. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, national origin, age, disability, protected veteran status, or any other status protected by applicable law.
