About The Position
Every compressor and engine that keeps oil, gas, and power moving across North America depends on parts machined to the tightest tolerances — and for over 190 years, that precision has run through Cooper Machinery Services. As the OEM behind legendary product lines like Cooper-Bessemer™, Ajax™, Superior™, and Enterprise, we're looking for a Machinist III to bring hands-on craftsmanship and CNC expertise to our Pacific Northwest facility. If you take pride in work measured in thousandths of an inch, and you want that precision to matter to a global energy infrastructure, this is your shop floor.

- 5–8 years of CNC machining experience, ideally in oil & gas, power generation, or heavy equipment.
- Advanced skill with precision measuring tools — dial and Vernier calipers, ID mics, depth mics, ball mics, and similar instruments.
- Certified to operate a forklift, pallet jack, and crane.
- Comfortable with a range of metal-cutting machinery and strong mechanical aptitude.
- Able to lift at least 40 pounds and perform physical work involving standing, bending, and kneeling.
- Solid math, computer, and communication skills, with the ability to read and act on product specifications and drawings.
