Machinist IV SR

Some of the most legendary engines in the world run on parts only a skilled machinist can make.

Since 1833, Cooper Machinery Services has built and serviced equipment that keeps power, pipelines, and ships moving. As a Machinist IV in our Deer Park Service Shop, you'll work from blueprints to produce precision one-off parts and restore turbocharger components, using both CNC and manual machines. No two jobs look the same, and every part you finish goes back into the field. If you're a seasoned machinist who wants to put your craft to work on iconic equipment, we want to meet you.
