CNC Engineer

Job Summary

The CNC Engineer plays a critical role in developing, improving and sustaining high-precision machining operations. Using advanced CAM software, the CNC engineer develops and refines CNC programs, enhances tooling strategies, and ensures process reliability. This position is ideal for a master CNC Machinist with deep technical knowledge, a passion for continuous improvement, and strategic problem-solving abilities within an aerospace manufacturing environment.

Essential Duties and Responsibilities 

The duties and responsibilities described are not a comprehensive list and additional tasks may be assigned. To perform this job successfully an individual must be able to perform each essential duty satisfactorily.

Machining & Setup

• Set up, operate, and optimize CNC machine tools (multi-axis milling and turning).
• Perform CNC program proofing, validate first-article setups, and ensure reliable, efficient, and safe production.
• Evaluate and improve workholding, feeds/speeds, and toolpaths for performance and repeatability.

Tooling & Process Development

• Develop and maintain tooling standards; verify adherence across production processes.
• Design tooling sketches and test protocols for evaluating new machining techniques.

Automation & Continuous Improvement

• Collaborate with Programming and Manufacturing Engineers to develop and optimize machining processes suitable for automation (robotic loading, in-process inspection & probing) to support lights-out manufacturing.
• Lead continuous improvement projects targeting quality, cost, and throughput optimization.
• Apply Lean Manufacturing principles (e.g., 5S, waste reduction, standard work) to machining processes to improve efficiency, reduce lead times, and eliminate non-value-added activities.

Root Cause & Process Analysis

• Use analysis tools (5-Why, Fishbone, FMEA) and trend data to conduct root cause analysis for machining failures and implement sustainable corrective actions.

Documentation & Standards

• Manage machining documentation, including setup sheets, tooling files, and manufacturing inspection plans.

Training & Leadership

• Train machinists and setup personnel; act as technical mentor and process expert.

Qualifications, Experience and Education Requirements

Education & Experience

• High School Diploma or Equivalent (Required)
• 5+ Years of experience in Precision CNC Machining (Multi-axis milling and/or turning)
• Technical Certificate or Associate’s degree in a related field (preferred)

Technical Knowledge & Experience

• Hands-on experience as a machinist for precision (Multi-axis) CNC manufacturing in aerospace, defense, or medical.
• Experience with CAM & CNC Simulation software (e.g., Mastercam, Vericut, Fusion 360).
• Deep understanding of G-code, canned cycles, and probing routines for automation.
• Demonstrated ability to machine tight-tolerance parts using aluminum, steel, and aerospace-grade alloys.
• Understanding metal behavior & mechanics in a machining environment (chip formation, vibration, distortion, heat transfer, etc.)
• Expertise in cutting tool geometry, fixture design, and tool life management.

Inspection & Quality

• Proficient with inspection tools (micrometers, calipers, height gauges).
• Ability to interpret GD&T, blueprints, manufacturing drawings & 3D part models.
• Familiarity with inspection processes, run charts, and SPC data.

Problem Solving & Leadership

• Proven experience solving machining issues and driving root cause resolution with speed and confidence
• Experience leading or managing Continuous Improvement initiatives such as scrap reduction or cycle time improvements.
• Strong communication skills to interface across production, programming, and quality teams.

Software & Documentation

• Experience with standard MS Office tools (Excel, Outlook), ERP/MES and project tracking software.
• Proficient in documentation management and maintaining up-to-date process records.
