Advanced CNC Programmer III - Multi-Tasking Machines (CNCPR006296)

RBC•Tucson, AZ

29d•Onsite

About The Position

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.

Requirements

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.
This role is subject to compliance with the International Traffic in Arms Regulations (ITAR) and the Export Administration Regulations (EAR), which requires the incumbent to be either a U.S. citizen, lawful permanent resident [“green card” holders] or have refugee or asylee status. Non-US Citizens may be restricted from certain programs.

Nice To Haves

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.

Responsibilities

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.
