Machinist III SR

Every legendary engine and compressor Cooper Machinery Services has built since 1833 started with a machinist who could turn a print into a precision part. As a Machinist III, you'll bring that same skill to the shop floor — machining, repairing, and restoring the one-off parts and tooling that keep our customers' operations running around the world.

This is hands-on work for someone who takes pride in tight tolerances and a clean finish. If you know your way around a manual lathe and a mill, and you want your craftsmanship backed by a company with 190+ years of engineering heritage, we want to hear from you.

WHAT YOU WILL DO

• Machine parts to spec on manual lathes, mills, and drills, and support repair/restoration of parts for our turbocharger service business.

• Read and interpret blueprints, drawings, and job cards to determine dimensions, tolerances, and machining requirements.

• Perform dimensional layout and inspection on finished parts, completing documentation to confirm conformity to print.

• Set up and secure holding fixtures, cutting tools, and workholding, then monitor feed and speed throughout the machining process.

• Adjust machine offsets (wear, geometry, cutter compensation) and execute the surface finishes each job calls for.

• Independently operate and set up multiple machine types, applying advanced trade math to complex prints and specifications.

• Deburr, stamp, and finish parts to specification, and keep your work area clean and safe — chips swept, oil disposed of, PPE on.

• Follow all safety protocols, including machine guarding, proper lifting technique, and slip/fall prevention.

WHO YOU ARE

• High school diploma or GED from an accredited school or institution.

• 5–8 years of manual machining experience, ideally in oil & gas, power generation, heavy equipment, or automation & controls.

• Advanced, hands-on knowledge of precision measuring tools — dial and Vernier calipers, ID mics, depth mics, ball mics, and similar.

• Mechanical aptitude allowing you to be versatile and help on the mechanical side as well when needed.

• Comfortable with a variety of metal-cutting machinery and confident reading and responding to product specifications and drawings.

• Able to lift at least 40 lbs. and handle the physical demands of the shop floor — standing, bending, kneeling.

• A dependable, safety-focused self-starter who communicates well, works effectively in a team, and adapts as priorities shift.

PREFERRED

• Vo-Tech certificate in machining or a related trade.
