Senior Injection Molding Process Engineer information

What are the key skills and qualifications needed to thrive as a senior injection molding process engineer?

To thrive as a Senior Injection Molding Process Engineer, you need a deep understanding of polymer science, mold design, process optimization, and typically a degree in engineering or a related field. Expertise with CAD software, process simulation tools, and familiarity with quality systems like ISO 9001 are commonly required, along with certifications such as RJG or Six Sigma. Strong analytical thinking, problem-solving abilities, and effective communication are essential soft skills for collaborating with cross-functional teams and troubleshooting production issues. These skills ensure efficient production, high-quality output, and continuous improvement in complex manufacturing environments.

What does a senior injection molding process engineer do?

A Senior Injection Molding Process Engineer is responsible for designing, optimizing, and troubleshooting the injection molding process used to manufacture plastic parts. They oversee process improvements, ensure product quality, and collaborate with cross-functional teams to meet production goals. Additionally, they may develop and implement new molding technologies, train staff, and support maintenance of equipment to ensure efficient and reliable operations.

What is the difference between Senior Injection Molding Process Engineer vs Injection Molding Technician?

AspectSenior Injection Molding Process EngineerInjection Molding Technician
CredentialsBachelor's degree in engineering or related field, certifications in process optimizationTechnical diploma or associate degree, on-the-job training
Work EnvironmentDesigning processes, analyzing data, improving production efficiencyOperating machinery, performing setup and maintenance
ResponsibilitiesProcess development, troubleshooting, process validationMachine operation, quality checks, routine maintenance

The Senior Injection Molding Process Engineer focuses on process design, optimization, and troubleshooting, requiring higher-level technical skills and education. In contrast, the Injection Molding Technician handles daily machine operation and maintenance tasks. Both roles are essential in the manufacturing environment but differ in scope and responsibilities.

What are the common challenges faced by senior injection molding process engineers when introducing a new mold into production?

Senior Injection Molding Process Engineers often encounter challenges such as optimizing process parameters for new molds, ensuring part quality meets specifications, and troubleshooting issues like warpage or incomplete filling. Collaboration with design, tooling, and quality teams is essential to address these challenges and implement effective solutions quickly. Additionally, balancing production efficiency with consistent quality requires careful monitoring and adjustment during the initial production runs.

Manufacturing Process Engineer - Extrusion Blow Molding

Flexcraft

Neptune City, NJ • On-site

$90K - $115K/yr

Full-time

Re-posted 19 days ago

Job description

Flexcraft is growing—and we’re hiring a hands-on Process Engineer with extrusion blow molding experience to help improve performance, reduce scrap, and support new product launches.

If you’re currently working in plastics manufacturing and want a role where you can own the process, solve real problems, and drive measurable results, this is worth a look.

Why Engineers Make the Move
  • Competitive salary based on experience (aligned to experienced plastics engineers)
  • Work directly on blow molding processes—not just theoretical work
  • High-visibility role with ownership of scrap, cycle time, and uptime
  • Opportunity to implement improvements, not just recommend them
  • Stable, growing manufacturing environment
What You’ll Be Working On
  • Extrusion blow molding processes
  • Polymer materials and process parameters
  • Cycle time, scrap reduction, and productivity improvements
  • Tooling, molds, and equipment performance
  • New product launches and process validation
What You’ll Do
  • Optimize processes to improve cycle time, quality, and efficiency
  • Troubleshoot production issues directly on the floor
  • Lead root cause analysis and implement permanent solutions
  • Support new product launches, mold trials, and validations
  • Partner with Production, Maintenance, and Quality teams
  • Develop SOPs and standardize best practices
What We’re Looking For
  • 5+ years of process engineering experience in plastics manufacturing
  • Hands-on experience with extrusion blow molding strongly preferred
  • Proven ability to troubleshoot and optimize processes in production
  • Strong understanding of materials, tooling, and molding equipment
  • Experience with SPC, DOE, or Six Sigma tools (preferred)
  • Comfortable working on the production floor—not just at a desk
Work Environment & Schedule

This is an onsite, hands-on role supporting a 24/7 manufacturing operation.

The position requires regular presence on the production floor and alignment with 12-hour production shifts as needed to support troubleshooting, process improvements, and key production activities.

This structure allows you to be closer to the process, respond in real time, and make faster, more effective improvements—not just analyze problems after the fact.

A typical day could include troubleshooting a process issue on the floor, running a trial, and working directly with operators to stabilize and improve performance.
