Advanced CNC Programmer III - Multi-Tasking Machines; CNCPR

Position Summary

RBC Bearings’ Sargent Facility in Tucson, Arizona is seeking an Advanced CNC Programmer III with deep expertise in programming multi‑tasking CNC machines (mill/turn, multi‑axis, live tooling) using Mastercam
.

This role is critical to driving production efficiency, machining excellence, and process capability for complex, tight‑tolerance aerospace and industrial bearing components. The ideal candidate is a technically elite CAM professional who takes ownership of their work, proves out processes on the shop floor, mentors others, and continuously raises performance standards through innovation and collaboration.

• Program, optimize, standardize and maintain CNC programs for complex multi‑tasking machines (multi‑axis mills, lathes, mill/turn platforms) using Mastercam.
• Analyze engineering drawings, GD&T, and model‑based definitions to determine optimal machining strategies and metal removal techniques.
• Develop efficient, repeatable machining processes that meet quality, cost, and delivery objectives with focus on spindle‑up time and some aspects of lights‑out machining during off‑shifts.
• Create and maintain CNC programs, setup sheets, tooling lists, work instructions, and program standards.
• Design and optimize tooling and work‑holding solutions in collaboration with Manufacturing Engineering and other stakeholders.
• Prove out new programs on the shop floor; troubleshoot machining, tooling, and process issues as they arise.
• Validate first‑piece inspections using inspection equipment to ensure conformance to print.
• Optimize post processors to minimize and eliminate manual code edits and improve programming efficiency.
• Drive cycle time reduction, tool life improvements, scrap reduction, and overall throughput improvements.
• Support new product introductions (NPI), process validation activities, and engineering changes.
• Create and maintain tooling documentation, tooling libraries, and tool life management systems.
• Champion Lean and continuous improvement initiatives (setup reduction, waste elimination, variation reduction).
• Develop programming and setup standards; train Manufacturing Engineers and Machinists in best practices.
• Mentor less experienced programmers and machinists and provide technical leadership on the shop floor.
• Ensure all work complies with RBC Bearings’ quality, safety, and manufacturing standards.

• Minimum High School Diploma or GED required, Engineering degree preferred.
• 5–10+ years of directly related CNC programming experience in a precision manufacturing environment.
• Proven expertise programming multi‑tasking CNC machines (mill/turn, multi‑axis platforms).
• Advanced proficiency with Mastercam (mill, lathe, multi‑axis, mill/turn modules).
• Strong practical knowledge of G‑code programming.
• Solid understanding of GD&T and ability to interpret complex engineering drawings.
• Experience in machining tight‑tolerance components in aerospace, defense, or high‑precision industrial applications.
• Strong knowledge of cutting tools, fixturing, materials, and machining best practices.
• Competency in metrology; ability to validate first‑piece runs and support gage studies.
• Excellent problem‑solving skills with a continuous improvement mindset.
• Strong communication and documentation skills (Word, Excel, Outlook).
• Motivation, reliability, attendance, and punctuality are essential.

• Experience working within regulated quality systems (AS9100, ISO, or similar).
• Familiarity with bearing manufacturing or precision rotating components is a plus.
• Experience supporting automation‑enabled or lights‑out machining environments.
• Ability to customize and maintain Mastercam post processors for specific machine controls.
• Experience with Fanuc, Siemens, Okuma, and Mazatrol controllers is a plus.
• 2‑or 4‑year technical degree (Associate’s or Bachelor’s) from an accredited institution.

• Results‑driven with a strong sense of ownership and accountability
• Highly organized with exceptional attention to detail
• Self‑motivated, dependable, and committed to world‑class manufacturing execution
• Strong collaborator who works effectively across engineering,…
