Senior CNC Programming Toolmaker — Injection Mold Lead

Ingersoll Rand•St. Francis, WI

About The Position

At 6:00 a.m., you step into our St. Francis facility, review the day’s build plan, and load up your first program. By mid-morning, you’ve translated a complex mold design into precise toolpaths, set up a 3–4 axis VMC, and verified offsets. After lunch, you’re collaborating with an engineer on a tight-tolerance insert, moving from CAD/CAM to G-code/M-code edits, and finishing on a wire EDM. Before clocking out, you’ve validated critical dimensions with micrometers and calipers, documented results, and left the cell spotless and safe for the next day. For over 160 years, Ingersoll Rand has advanced mission-critical flow creation and life science technologies—think compressors and precision handling of liquids and gases—that boost productivity, efficiency, and sustainability. Backed by 80+ brands and serving life sciences, food and beverage, clean energy, manufacturing, and infrastructure, we operate with an entrepreneurial spirit and ownership mindset.
