CNC Programmer III – Milling

PacAero•Agawam, MA

3h•$40 - $53•Onsite

About The Position

At PacAero Agawam, we manufacture high-precision components for the aerospace, defense, and medical industries. Our work involves complex geometries, tight tolerances, and challenging machining applications where technical expertise and attention to detail make all the difference. We're looking for an experienced CNC Programmer III with strong Mastercam expertise and hands-on experience programming 3, 4, and 5-axis CNC milling machines. This isn't a behind-the-desk programming position. We need someone who enjoys being on the manufacturing floor, proving out programs, troubleshooting machining challenges, and working directly with machinists to get parts running efficiently and accurately. If you're someone who takes pride in seeing a complex part go from programming to a successful production run, we'd like to meet you.

Requirements

3-5+ years of progressive CNC programming experience in a precision manufacturing environment.
Advanced Mastercam programming experience required.
Demonstrated experience programming 3, 4, and 5-axis CNC milling machines required.
Strong hands-on machining background, including machine setup, program prove-outs, and troubleshooting.
Advanced understanding of multi-axis machining strategies, toolpath development, cutting tools, feeds and speeds, and workholding.
Ability to independently develop and troubleshoot complex machining programs.
Strong ability to interpret engineering drawings, CAD models, GD&T, and tight-tolerance specifications.
Experience optimizing machining processes for quality, efficiency, and repeatability.
Strong communication, problem-solving, and collaboration skills.

Nice To Haves

Experience with Haas and/or Okuma CNC equipment preferred.
Experience machining aluminum, stainless steel, and other precision materials preferred.
Background in aerospace, defense, medical, or similarly regulated manufacturing environments preferred.

Responsibilities

Develop, create, and optimize complex 3, 4, and 5-axis CNC milling programs using Mastercam.
Program precision components from CAD models, engineering drawings, and customer specifications.
Work hands-on with CNC equipment to support machine setups, first-piece runs, program prove-outs, and production readiness.
Develop machining strategies, including toolpath optimization, cutting parameters, tooling selection, and workholding approaches.
Troubleshoot programming, tooling, setup, and machining issues directly on the manufacturing floor.
Partner with machinists to improve cycle times, reduce scrap, enhance tool life, and maintain consistent part quality.
Support complex multi-axis machining applications involving tight tolerances and intricate geometries.
Review and interpret engineering drawings, GD&T, and technical specifications to ensure machining accuracy.
Create and maintain CNC programs, setup documentation, tooling lists, and process instructions.
Collaborate with Manufacturing Engineering, Quality, and Production to resolve manufacturing challenges and improve processes.
Support new product introductions, prototypes, and the transition of new programs into repeatable production processes.
Provide technical guidance and programming support to machinists and less-experienced programmers.
Identify and implement continuous improvement opportunities that increase machining efficiency, quality, and overall equipment performance.
Develop and maintain accurate CNC programs, ensure machining processes meet engineering specifications and quality requirements, identify and communicate quality concerns, support proper documentation and traceability, and work with Manufacturing Engineering, Quality, and Production to resolve issues and improve machining processes.
