  • Support compliance of manufacturing processes, documentation, and supplier controls with internal quality systems and regulatory requirements (FDA, ISO).
  • Utilize engineering tools (e.g., SolidWorks, Minitab, DOE) to support product and process development and troubleshooting.
  • Support development of standardized work and process documentation to enable knowledge transfer and long-term continuity.
  • Learn and apply elements of the NBS Next business model at the production floor level to support operational excellence initiatives.

Education and Experience Requirements
  • Bachelor's Degree in Mechanical, Manufacturing, Plastics/Polymer, Industrial, Biomedical Engineering, or related field required.
  • 1-3 years of engineering experience in a manufacturing or regulated environment (medical device, pharmaceutical, or similar) preferred.
  • Internship or co-op experience in medical device, plastics/injection molding, supplier quality, or cleanroom manufacturing is a plus.
  • Exposure to manufacturing processes such as injection molding, silicone molding, or assembly technologies (e.g., ultrasonic welding, bonding) is preferred.

Required Skills and Abilities
  • Strong organizational and time management skills with the ability to independently complete assigned tasks in a fast-paced manufacturing environment.
  • Proficient in Microsoft Office and SolidWorks; exposure to statistical tools (e.g., Excel, Minitab) and data analysis techniques preferred.
  • Working knowledge of problem-solving and root cause analysis tools such as 5 Whys, Fishbone diagrams, and basic CAPA methodologies.
  • Familiarity with engineering documentation, validation principles (IQ/OQ/PQ), and production support processes in a regulated environment.
  • Effective verbal and written communication skills, with the ability to collaborate cross-functionally and engage with external suppliers in a professional manner.
  • Demonstrated ability and willingness to learn new manufacturing processes, including injection molding, silicone processing, and assembly techniques.
