Rolls‑Royce, a leader in manufacturing solutions, offers a culture that values inclusion, creativity, and professional development. It is recognized as the top employer in the Engineering & Manufacturing category on the Forbes Top Employers for Engineers list for 2025. Power Systems, one of three core businesses, delivers world‑class solutions across energy, industrial, marine, and defense sectors. North America is a key growth market supporting resilient and sustainable power solutions.

The CNC Operator runs the machining centers in crankcase manufacturing, machining crankcases to exact specifications with in‑process quality assurance. The role offers a clear development path: entry with line boring (no prior CNC experience) progressing to CNC machining on Burkhardt & Weber machines.

• Set up and machine crankcases according to specifications, routings, control plans, and drawings, on the line boring machine and, at the advanced level, on the Burkhardt & Weber (B&W) machining centers with Sinumerik One control system
• Bore and align the bearing alleys of the crankcase, including the camshaft and crankshaft bores, re-boring as required to achieve precise alignment
• Clamp, reclamp, and unclamp crankcases, monitor the process, and correct as necessary
• Monitor, change, correct, and adjust tools as required
• Study machining instructions, routings, control plans, job orders, and blueprints to determine dimensional and finish specifications, sequences of operations, machine setups, and tooling requirements
• Select the appropriate tools and materials for the preparation of crankcase components
• Set up, adjust, and operate the basic machine tools and many specialized or advanced variation tools to perform precision machining operations
• Perform fine‑tuning through sample cuts and optimize the CNC program with regard to tool durability, collision prevention, and program sequencing
• Observe machine operation to detect conditions such as dull cutting tools or excessive vibration and adjust to compensate

• Entry level, line boring:
  Completed vocational training as a machine and plant operator or a comparable qualification, or a U.S. equivalent such as a mechanical or machining trade school certificate, an Associate's Degree, or relevant hands‑on experience in a machining environment
• Direct work as CNC Operator on the B&W machines:
  Completed vocational training as an industrial mechanic specializing in production technology, or a comparable 3.5-year apprenticeship in a metalworking profession, or 2 years of trade school or an equivalent Associate's Degree, or 3 years of experience in a heavy‑duty machining environment; several years of experience operating NC-controlled machining centers; and knowledge of Sinumerik One control system
• Shift: Off-Shift hours are 7:30pm to 6:00am, Monday night through Thursday night.
• All levels:
  Strong quality awareness and a high sense of responsibility; physically resilient, reliable, and committed; willingness to work shifts and occasional weekends; and the ability to work overtime as needed
• Applicants must be authorized to work for any employer in the U.S. without sponsorship. We are unable to sponsor or take over sponsorship of an employment Visa at this time

• Experience operating Burkhardt & Weber (B&W) machining centers
• Knowledge of Sinumerik One control system would be particularly advantageous
• Several years of experience on a conventional boring mill (e.g., Collet) would be an advantage
• Experience machining crankcases or large cast components
• Intermediate knowledge of CNC controls, machines, and tools, including their designs, uses, repair, and maintenance
• Intermediate knowledge of arithmetic, algebra, geometry, calculus, statistics, and their applications
• Basic ability to interpret Statistical Process Control (SPC) and operate scanning…
