Flexcraft • Full-time • Neptune City, New Jersey, United States • $90k - $115k / year • 1w ago

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.
