Why this job is worth considering

Primetals Technologies USA is part of a global metals-technology leader with more than 1,000 people across 12 locations in 10 states, backed by decades of engineering heritage in the steel and metals industry. This Level 3 Grinding Machinist role is a senior, largely independent position: you'll set up, program, and run CNC OD/ID cylindrical grinders producing high-precision components for real production equipment, not routine flat work. Multiple shifts are open, and the role comes with a clear path toward Manufacturing Team Lead or Manufacturing Engineer along with company-supported development. With pay up to $40.65 an hour and full benefits, it's a strong fit for an experienced grinding machinist ready to lead as well as machine.

What you'll be doing

• Independently set up, load and verify programs, set part zeros, and run multi-diameter CNC cylindrical grinding machines
• Perform complex grinding operations including finishing and polishing
• Set up and use appropriate workholding — centers, chucks, and steady rests — for complex geometries
• Monitor and verify micro-inch surface finishes (Ra) using profilometers
• Select, mount, and balance grinding wheels (aluminum oxide, silicon carbide, or CBN) based on material specifications, and perform wheel dressing and truing
• Develop, modify, and optimize CNC programs, and make geometry/thermal offset adjustments to correct for wheel wear and material changes
• Interpret complex blueprints and GD&T with multiple datums, and perform in-process and final inspections
• Train and mentor other operators, and drive process improvements using lean principles (SMED, 5S, value stream mapping)

Machines, controls and software

This role runs on Studer, Danobat, and Campbell CNC OD/ID cylindrical grinders, programmed on Fanuc or OEM programming software, plus manual grinders as needed.

What we're looking for

Required

• 5+ years of grinding machining experience, including CNC OD/ID cylindrical grinding
• Advanced understanding of grinding principles, materials, and process dynamics
• Ability to interpret complex blueprints and GD&T with multiple datums
• High competency with precision measurement instruments
• Demonstrated initiative, problem-solving ability, and technical leadership
• Experience training or mentoring other machinists/operators

Pay, benefits and schedule

This role pays $27.10–$40.65 per hour, full time, with multiple shifts open. Primetals Technologies USA offers a full benefits package companywide, including 401(k) match, health, dental, and vision insurance, life and disability insurance, an employee assistance program, paid time off, and tuition reimbursement.
