Job Description

Job Description

Day-in-the-Life at Atlas Fibre (Northbrook, IL)

You start your morning on the shop floor, reviewing overnight part runs on our Fanuc and Okuma VMCs. A machinist flags a fixturing challenge on a composite part—together you diagnose the issue, adjust the workholding concept, and update a Mastercam program to stabilize the cycle. By mid-day, you’re running a quick capability study, documenting GD&T-critical features, and finalizing setup sheets for a new NPI job transitioning into production. You wrap up by aligning with Quality and Operations on corrective actions and planning out the next wave of continuous improvements.

Impact You’ll Make

• Provide daily, hands-on engineering support to a fast-paced machining operation
• Troubleshoot machining, quality, tooling, fixturing, and process issues to keep work flowing
• Develop and refine machining processes for composite and high-performance plastic components
• Create and optimize CNC toolpaths/programs in Mastercam
• Design and implement effective workholding and fixtures
• Lead root-cause investigations and implement durable corrective actions
• Collaborate closely with machinists, programmers, quality, and leadership to elevate performance
• Author setup sheets, work instructions, process documentation, and engineering standards
• Support NPI from development through a reliable launch into production
• Assist with equipment validation and process capability studies; drive continuous improvement
• Assess manufacturing risks and implement practical solutions to boost quality and throughput

What You’ll Bring Required

• 5+ years in Manufacturing Engineering, CNC Programming, or related roles
• Deep understanding of CNC machining processes
• Mastercam (or similar CAM) proficiency
• Ability to read engineering drawings and CAD models
• Working knowledge of GD&T and inspection methods
• Hands-on troubleshooting of manufacturing and quality issues
• Strong grounding in tooling and machining fundamentals
• Excellent problem-solving and communication skills
• Comfort operating in a high-mix, fast-paced, on-site manufacturing environment

Preferred

• Experience machining plastics, composites, or engineered materials
• Familiarity with Vericut or comparable simulation tools
• Fixture design and workholding development experience
• Exposure to Renishaw probing and machine calibration
• Lean/continuous improvement background
• Multi-axis machining exposure (4-axis and 5-axis)
• Knowledge of process validation, capability studies, and basic statistics
• NPI and production launch support experience

Location, Schedule, and Workstyle

• On-site in Northbrook, IL
• Full-time, Monday–Friday
• Day shift

Compensation & Benefits

• Salary: $125,000–$150,000 (commensurate with experience and skill)
