Job summary

Randstad is seeking an experienced CNC Milling Process Engineer in Broadview, IL to optimize precision machining, design efficient operations, and bridge engineering concepts with shop-floor execution. You will lead CNC milling process design, tool selection, fixture design, and cycle-time reduction across prototyping to high-volume production, while ensuring ISO 9001:2015 and ITAR compliance.

Collaborate with machinists, quality, and management to drive continuous improvement and standard work.

Qualifications

• 5+ years of experience in CNC milling engineering, process design, or high-precision contract machining environment.
• Proficient in CAD (SolidWorks or AutoCAD) and CAM software (Mastercam, GibbsCAM, or Esprit, or equivalent).
• Deep understanding of GD&T (ASME Y14.5) and cutting tool geometry.
• Hands-on familiarity with vertical/horizontal CNC milling centers, pallet changers, and automated part handlers.
• Knowledge of ISO 9001:2015 and ITAR requirements.
• Bachelor's degree in Mechanical Engineering, Manufacturing Engineering, or equivalent hands-on machining/engineering background.

Responsibilities

• Own the Process: Develop manufacturing sequences, cutting parameters, and standard work instructions for complex 3-, 4-, and 5-axis milling operations.
• CAM Programming & Simulation: Program, verify, and post-process high-efficiency G-code/M-code programs using Mastercam, GibbsCAM, or hyperMILL, relying heavily on digital simulation to guarantee zero-crash execution.
• Tooling & Fixture Design: Design custom, rigid workholding, modular fixtures, and specialized cutting tool assemblies in CAD to slash setup times and guarantee repeatable tolerances.
• Floor Collaboration: Serve as the go-to technical partner for setup technicians and machinists to troubleshoot chatter, optimize chip load, and eliminate cycle bottlenecks.
• Launch New Products (NPI): Shepherd parts from CAD/STEP files and customer blueprints through prototype development, FAI, and handoff to full-scale production.
• Drive Continuous Improvement: Apply Lean and SMED principles to systematically eliminate scrap, standardize setups, and keep spindle uptime high.
