CNC Machinist/Programmer

HEICO Corporation

About The Position

The CNC Machinist / Programmer is responsible for creating, managing, and optimizing CNC programs using Mastercam for 3 to 5-axis milling machines. This role requires a strong programming background to analyze engineering data, develop tooling strategies, and produce setup documentation that supports the broader production team. The CNC Machinist / Programmer sets up and operates milling machines to machine aluminum and trim composite parts, interprets blueprints and engineering specifications, and monitors quality to ensure all work meets customer tolerances and company standards. Candidates with additional experience programming and operating a gantry-style CMM for dimensional inspection are strongly preferred, as this is a desired secondary capability for the role.

Requirements

Associate degree in Machining Technology or equivalent relevant work experience (2–3 years)
3–5 years of expert-level Mastercam experience with 3, 4, and 5-axis programming required
Excellent knowledge of G-code required
Ability to lift and/or move up to 25 lbs frequently
Ability to stand for extended periods and work in environments requiring ear and respiratory protection
Self-motivated, self-managed, and capable of working independently or as part of a collaborative team
Team player who actively contributes to continuous improvement initiatives
Expert proficiency in Mastercam CAM software for 3, 4, and 5-axis programming
Strong working knowledge of G-code and CNC machine setup, monitoring, and change-out procedures
Ability to analyze engineering drawings, blueprints, and design data to develop effective machining strategies
Experience creating setup and tooling documentation to support shop floor operations
Proficiency with machine probing for in-process part measurement
Ability to apply mathematical functions related to machining, tooling design, and dimensional computation
Experience in both production and prototyping environments
Strong mechanical aptitude and meticulous attention to detail
Proficient in Microsoft Office (Excel, Word, PowerPoint)
Effective written and verbal communication skills, with the ability to collaborate across functional teams

Nice To Haves

Candidates with additional experience programming and operating a gantry-style CMM for dimensional inspection are strongly preferred
CMM programming and operation experience preferred, ideally with gantry-style or large-format equipment
Familiarity with GD&T and its application to dimensional inspection is a plus
CMM programming and operation experience preferred but not required

Responsibilities

Create, modify, and store original CNC programs using Mastercam for 3, 4, and 5-axis milling machines

Produce setup documentation, tooling documentation, and shop-aided drafting prints to support operators and machinists
Verify and simulate CNC programs against CAD models to ensure accuracy prior to running
Troubleshoot and resolve program and process issues, coordinating with other functional areas as needed
Plan, design, and produce work holding and job-specific fixtures as required
Assist operators and machinists with program processes and provide in-process production support
Ensure parts and tools are loaded correctly and quality is consistently maintained throughout each assignment
Change and adjust cutters as required to meet quality and tolerance requirements; ensure machinery and tools are properly maintained
Ensure accurate documentation is entered on Manufacturing Orders, including correct quantities and specification recording
Focus on continuous improvement through increased throughput and reduced changeover time
Stay current with new versions of Mastercam and related programming software
When required, program and operate the company's gantry CMM to perform dimensional inspections and generate inspection reports
Perform other duties as assigned
