CNC Mill Process Engineer

job summary:

Our client is seeking an experienced CNC Milling Process Engineer to optimize precision machining processes, design efficient manufacturing operations, and bridge the gap between engineering concepts and shop-floor execution. In this role, you will lead CNC milling process design, tool selection, fixture design, programming support, and cycle-time reduction across short-run prototyping and high-volume production lines. You will work closely with machinist teams, quality control, and management to maintain strict ISO 9001:2015 and ITAR compliance standards

location: Broadview, Illinois job type: Permanent salary: $115,000 - 125,000 per year work hours: 6am to 4pm education: No Degree Required

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], 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.

What You Bring

• Experience: 3+ years in manufacturing engineering or senior CNC programming within a high-precision, multi-axis machining environment.
• Software Fluency: Deep expertise in CAD modeling (SolidWorks, Inventor, or similar) and CAM systems (Mastercam, GibbsCAM, or hyperMILL).
• Technical Depth: Strong understanding of GD&T (ASME Y14.5), cutting tool geometry, speeds/feeds optimization, and multi-axis kinematics.
• Quality & Standards: Working knowledge of First Article Inspection (FAI), root-cause analysis (5-Why, 8D), and operating under ISO 9001 / AS9100 / ITAR environments.
• Education: B.S. in Mechanical/Manufacturing Engineering or equivalent hands-on machining/engineering background.

Why Join Us?

• Comprehensive medical, dental, and vision insurance
• 401(k) matching program
• Competitive PTO and paid holidays
• Direct investment in training, modern machine tool tech, and software upgrades

qualifications:

Experience: 5+ years of experience in CNC milling engineering, process design, or high-precision contract machining environment.

Technical Software: Proficient in CAD (SolidWorks or AutoCAD) and CAM software (Mastercam, Esprit, or equivalent).

Machining Knowledge: Deep understanding of cutting tool geometry, speeds/feeds for complex metals (stainless steel, titanium, aluminum, alloys, plastics), and geometric dimensioning & tolerancing (GD&T?).

Equipment Experience: Hands-on familiarity with vertical/horizontal CNC milling centers, pallet changers, and automated part handlers.

Certifications & Standards: Knowledge of ISO 9001:2015? and ITAR? requirements.

Education: Bachelor's degree in Mechanical Engineering, Manufacturing Engineering, or equivalent combination of technical education and hands-on machinist experience.

Equal Opportunity Employer: Race, Color, Religion, Sex, Sexual Orientation, Gender Identity, National Origin, Age, Genetic Information, Disability, Protected Veteran Status, or any other legally protected group status.
