Build a Legacy. Keep Legendary Machines Running.


Since 1833, Cooper Machinery Services has built the engines and compressors that power the world's energy. Today, more than 22,000 units in our installed base depend on skilled hands to keep them running. As a Downstream Mechanic III, you'll be the expert those machines and our customers count on. You'll diagnose the toughest failures, lead overhauls on legendary Cooper-Bessemer™, Ajax™, and Superior™ platforms (and non-OEM equipment too), and help set the standard for craftsmanship in our Deer Park shop. You'll work with minimal supervision, mentor the people around you, and own your work from teardown to final inspection.


If you take pride in solving problems others can't, this is where your skills count.

  • Provide informal leadership and coaching to teammates, and oversee specialty contractors (QA/QC) as needed
  • Work within our Safety tenets and Stop Work Authority, and keep the shop clean, safe, and organized
  • Participate in training programs, risk management reviews, and safety meetings

Who You Are

  • High School Diploma or GED (or equivalent related work experience)
  • 5–8 years of progressive experience in mechanical maintenance and repair of compressors and pumps
  • Strong troubleshooting and root cause analysis skills, with the ability to execute overhaul, diagnostic, and upgrade-support work independently

  • A sense of ownership and accountability for the quality of your work
  • Able to read and understand technical procedures and governmental regulations
  • Able to work safely around rotating or moving equipment and wear required PPE

  • Valid driver's license
