Job description

Penn Manufacturing Industries is seeking a hands‑on CNC Engineer to support and improve precision CNC machining and programming operations. This role requires strong shop-floor engagement, demonstrated experience working with highly precise machining tolerances, and the ability to independently develop, optimize, and sustain manufacturing processes.

The Process Engineer II acts as a technical resource for production and quality teams, applying GD&T, Lean manufacturing, 5S, and Six Sigma tools to drive measurable process improvements while maintaining Penn Manufacturing Industries’ standards for quality, safety, and operational excellence.

Core Responsibilities (Mid‑Level Scope)

Hands-On CNC Machining & Programming

• Serve as a hands‑on manufacturing engineer, regularly working on the shop floor to support machining operations.
• Independently develop, optimize, and sustain CNC machining processes for tight-tolerance, precision components.
• Create, modify, and validate CNC programs to improve cycle time, quality, and repeatability.
• Troubleshoot complex machining, tooling, and fixturing issues in real time with machinists.
• Support Design for Manufacturability (DFM) reviews with emphasis on process capability and tolerance control.
• Ensure machining processes consistently meet highly precise machining tolerance requirements.

Process Ownership & Continuous Improvement

• Own assigned machining processes from setup through production sustainment.
• Identify and implement process improvements that reduce scrap, rework, and cycle time variation.
• Conduct root cause analysis and lead corrective actions for process-related issues.
• Develop and maintain standardized work instructions, setup sheets, and process documentation.

GD&T & Quality Integration

• Interpret engineering drawings and apply GD&T principles to production machining processes.
• Support first article inspections, capability studies, and ongoing process monitoring.
• Collaborate with Quality to address nonconformances and improve long‑term process stability.
• Ensure process capability aligns with customer and internal quality expectations.

Lean, 5S & Six Sigma Application

• Actively support Lean manufacturing initiatives, including 5S, visual management, and waste reduction.
• Participate in Six Sigma or structured problem‑solving projects focused on reducing variability in precision machining.
• Train and mentor machinists and operators on standard work and best practices.

Cross‑Functional Manufacturing Support

• Design fixturing, implement process improvements supporting continuous improvement activities
• Work daily with Production, Quality, and Engineering teams to support manufacturing execution.
• Assist with tooling selection, fixture improvements, and process planning.
• Support new product introductions by establishing robust and repeatable machining processes.

Required Qualifications (Process Engineer II)

• Bachelor’s degree in Manufacturing Engineering, Mechanical Engineering, or related field, or equivalent hands‑on manufacturing experience.
• 3–7 years of experience in CNC machining process engineering or manufacturing engineering.
• Strong hands‑on experience supporting CNC machining operations in a production environment.
• Demonstrated experience working in high‑precision machining environments with tight tolerances.
• Solid working knowledge of GD&T.
• Experience applying Lean, 5S, and continuous improvement methodologies.
• Tool/Fixture Design knowledge
• Ability to work independently while supporting team‑based manufacturing operations.

Preferred Qualifications

• Experience in precision or high‑mix manufacturing environments.
• Prior hands‑on machining background (operator, setup, tooling, or programming).
• Six Sigma Green Belt or equivalent certification.
• Experience with CAM software and tooling optimization for tight tolerance machining.
