CNC Programmer / Machinist

Job Description

Job Description

Role Overview

We are seeking a Principal CNC Programmer / Machinist to lead machining strategy, CNC programming, and complex process execution for aerospace and medical device components. This role is designed for a highly experienced professional who operates at the intersection of programming excellence, hands-on machining mastery, and shop-floor technical leadership.

This position is not a support role—it is a process owner role. The successful candidate will define how parts are machined, validate processes, resolve the most difficult manufacturing challenges, and serve as the highest level of machining and programming authority within the organization.

Core Responsibilities

CNC Programming & Process Ownership

• Own CNC programming strategy for complex aerospace/medical device components from print review through production release

• Develop, validate, and optimize CNC programs using CAM software and G-code

• Define machining methodologies including sequencing, toolpaths, cutting strategies, and risk mitigation

• Lead prove-outs, first-article runs, and process qualifications

• Optimize cycle time, tool life, surface finish, and process capability

Machining & Setup Execution

• Independently set up and run complex jobs on CNC mills and lathes, including:

  • Mills: Kitamura, Methods, Chevalier, Viper

  • Lathes: Takisawa, Hardinge, Yama Seiki

• Design and implement advanced fixturing, workholding, and tooling solutions

• Machine tight-tolerance, flight-critical components across a range of aerospace materials

• Troubleshoot and resolve complex machining, tooling, and process issues

Technical Leadership & Standards

• Serve as the primary subject matter expert for CNC programming and machining processes

• Establish and maintain machining standards, setup documentation, and best practices

• Provide technical guidance and mentorship to machinists and programmers

• Support engineering, quality, and production teams with manufacturability input (DFM)

• Participate in root cause analysis, corrective actions, and continuous improvement initiatives

Quality & Compliance

• Ensure all machining processes meet AS9100, FAA, and customer requirements

• Support first-article inspections, source inspections, and audit readiness

• Apply advanced GD&T interpretation to real-world machining decisions

Required Qualifications

• 10+ years of experience in aerospace or similarly regulated, high-precision manufacturing

• Expert-level CNC programming capability combined with hands-on machining experience

• Extensive experience with both CNC milling and CNC turning

• Advanced knowledge of GD&T and aerospace drawing interpretation

• Proven track record machining and programming tight-tolerance, high-complexity components

• Deep understanding of aerospace materials including aluminum, stainless steel, titanium, and nickel-based alloys

• Strong mechanical intuition and structured problem-solving skills

• Ability to operate with full autonomy and technical accountability

Preferred Qualifications

• Advanced 5-axis milling and/or multi-axis turning experience

• High proficiency with CAM software (Mastercam, Fusion 360, NX, or similar)

• Experience supporting prototype, first-article, and low-volume/high-mix aerospace work

• Prior involvement in PFMEA, process qualification, or manufacturing risk assessments

• Experience supporting AS9100 audits or customer source inspections

What This Role Offers

• Authority over CNC programming and machining strategy

• Ownership of the most complex and critical aerospace/medical device work

• Direct influence on process standards, tooling strategy, and shop capability

• A quality-driven, engineering-aligned manufacturing environment

• Compensation aligned with principal-level technical expertise

Education

• High school diploma or GED required

• Technical degree, formal apprenticeship, or equivalent advanced training strongly preferred

Work Environment

• Precision aerospace/medical device manufacturing facility

• Hands-on role requiring regular machine interaction

• Ability to lift up to 50 lbs

• Exposure to industrial machinery, cutting fluids, and metal chips
