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.

• 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.

• 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, , 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.

• 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.

• Most benefits are effective on your first day — no waiting period.
• Comprehensive medical, dental, and vision insurance.
• Company-paid life, AD&D, short-term, and long-term disability coverage (6-month short-term disability waiting period).
• Voluntary life, AD&D, and long-term disability buy-up plans.
• Voluntary accident, critical illness, and hospital indemnity insurance plans.
• 401(k) with up to 5% company match — employees are 100% vested on day one.
• Maternity and parental leave, Arc Fertility Benefits, and an Employee Assistance Program (EAP) for mental health support.
