These competencies ensure efficient production, high product quality, and innovation in plastic manufacturing environments.

What are some common challenges faced by Plastic Process Engineers in optimizing manufacturing processes?

Plastic Process Engineers often encounter challenges such as maintaining consistent product quality while scaling up production, troubleshooting equipment malfunctions, and minimizing material waste. They must continuously monitor and adjust processing parameters like temperature, pressure, and cycle time to ensure efficiency and compliance with specifications. Collaboration with design, quality, and maintenance teams is crucial to quickly resolve issues and implement process improvements. Staying updated with new materials and technologies also plays a key role in overcoming these challenges and advancing in the field.

What does a Plastic Process Engineer do?

A Plastic Process Engineer is responsible for designing, developing, and optimizing processes involved in the manufacturing of plastic products. They work with various types of plastic materials and molding technologies, such as injection molding, extrusion, and blow molding. Their duties often include troubleshooting production issues, improving process efficiency, ensuring product quality, and collaborating with design and production teams to implement best practices. They also play a key role in selecting materials, setting process parameters, and maintaining compliance with safety and environmental regulations.

What is the difference between Plastic Process Engineer vs Plastic Technician?

AspectPlastic Process EngineerPlastic Technician
CredentialsBachelor's degree in plastics engineering, chemical engineering, or related fieldTechnical diploma or associate degree in plastics technology or related field

Job description

Process Engineer

Applied Medical is a new-generation medical device company with a proven business model and commitment to innovation fueled by rapid business growth and expansion. Our company has been developing and manufacturing advanced surgical technologies for over 35 years and has earned a strong reputation for excellence in the healthcare field. Our unique business model, combined with our dedication to delivering the highest quality products, enables team members to contribute to a larger capacity than is possible in typical positions.

Position Description

As a Process Engineer at Applied Medical, you'll lead cross-functional improvement initiatives that drive consistency, efficiency, and scalability across a wide range of manufacturing systems. From component assembly to process validations and documentation, this role combines hands-on process ownership with strategic collaboration. You'll bridge the gap between design and production, ensuring our processes are compliant, optimized, and ready to scale.

Key Responsibilities:

  • Cross-Process Improvement: Analyze, document, and improve existing workflows for component-level manufacturing, including assembly, bonding, testing, and sub-processes beyond plastics.
  • Validation & Compliance: Lead and support equipment and process validations (IQ/OQ/PQ), working with quality and documentation teams to ensure regulatory alignment.
  • Tooling & Fixture Coordination: Collaborate with design and tooling engineers to evaluate or improve manufacturing fixtures and workflows.
  • Documentation Mastery: Own and maintain process documentation including SOPs, work instructions, validation protocols, and technical reports.
  • Project Ownership: Manage validation timelines, trials, and change implementation across multiple teams, including operations, tooling, and quality.
  • Technician Support: Train floor technicians on updated processes, documentation, or new procedures as workflows evolve.

Position Requirements

  • Bachelor's degree in Mechanical, Chemical, Bioengineering, or a related field
  • More than one year of industry experience in manufacturing, injection molding, or process engineering
  • Exposure to plastics manufacturing, component-level production, or contract manufacturing environments
  • Interest in process planning, optimization, and cross-team coordination
  • Proficiency with CAD software for basic design collaboration and documentation
  • Ability to communicate across departments and work in technician-facing environments
  • Strong analytical and documentation skills for recipe development, SOPs, and technical reporting
  • Project coordination mindset with a focus on execution and follow-through

Preferred

  • Hands-on experience with injection molding systems or plastics process development
  • Familiarity with validation protocols (IQ/OQ/PQ) and regulated manufacturing environments
  • CAD design ability beyond basics with SolidWorks, CATIA, or equivalent
  • Minitab or Excel-based data analysis for performance metrics or capability studies
  • Experience collaborating with cross-functional engineering and quality teams
  • Interest in developing scalable solutions for scrap reduction, cycle time efficiency, and process sustainability
  • Comfort with root-cause analysis, data collection, and continuous improvement techniques

If you're passionate about bringing order to complex workflows, documenting technical change, and working cross-functionally to refine how products are made, the Process Engineer role offers an exciting opportunity to make scalable impact in medical manufacturing.

Benefits

  • Competitive compensation range: $71,000 - $80,000 / year (California).
  • Comprehensive benefits package.
  • Training and mentorship opportunities.
  • On-campus wellness activities.
  • Education reimbursement program.
  • 401(k) program with discretionary employer match.
  • Generous vacation accrual and paid holiday schedule.

Please note that the compensation range may be adjusted in the future, and bonus and incentive compensation plans may apply.
