Machinist III MF

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.

WHAT YOU WILL DO

Machine parts to precise specifications using a CNC Mazak Mill with Mazatrol controls. Interpret blueprints, drawings, and specifications to determine dimensions and tolerances of finished work. Perform repair and restoration of parts to keep customer equipment running. Conduct dimensional layout on machined parts to verify conformity to prints and routing instructions, completing all required documentation. Set up and secure holding fixtures, cutting tools, jaw attachments, and materials on machines. Monitor machine feed and speed throughout the process, adjusting offsets for wear, geometry, and cutter compensation. Identify and execute the right surface finish for each job, then deburr and stamp parts to spec. Read job cards to determine product details, machining time, and quantities. Maintain a clean, safe work area and follow all PPE and safety protocols.

WHO YOU ARE

High School Diploma or GED from an accredited school or institution. 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. Flexible and dependable — willing to work overtime, weekends, and holidays as the business requires.

PREFERRED

Hands-on experience specifically with Mazak equipment and Mazatrol programming. Background machining large, complex reciprocating engine or compressor components. Track record of mentoring less experienced machinists on the floor. Familiarity with quality systems and formal inspection documentation in a manufacturing environment.
