Job description

If you are unable to complete this application due to a disability, contact this employer to ask for an accommodation or an alternative application process.

We are seeking a skilled CNC Programmer to develop, optimize, and maintain machining programs that support high-quality, efficient manufacturing operations. This role is responsible for translating engineering intent into effective machining strategies, ensuring parts are produced accurately, efficiently, and cost-effectively.

This is not a repetitive production programming role. We operate in a job shop environment where every project presents a new challenge. Success in this role requires a strong machining background, sound manufacturing judgment, and the ability to develop creative, efficient solutions for unique parts and applications.

What You'll Do

• Create, modify, and optimize CNC programs using Mastercam and other CAM software.
• Interpret engineering drawings, CAD models, and GD&T requirements to develop machining strategies.
• Select tooling, cutting parameters, and fixturing solutions to maximize performance.
• Simulate and verify toolpaths to ensure accuracy and prevent collisions.
• Support CNC machinists and operators with setup instructions and technical guidance.
• Troubleshoot programming, tooling, and machining issues on the production floor.
• Drive continuous improvement initiatives focused on reducing cycle times and increasing efficiency.
• Collaborate with Engineering, Production, and Quality teams to improve manufacturability and process performance.
• Maintain program documentation, revision control, and backups.
• Ensure all machining processes meet quality, safety, and customer requirements.

What We're Looking For

Required Qualifications

• 3+ years of CNC programming experience in a manufacturing environment.
• Strong machining background with a thorough understanding of machining processes, tooling, fixturing, and setup practices.
• Proficiency with CAM software, preferably Mastercam.
• Ability to read and interpret engineering drawings, specifications, and GD&T.
• Knowledge of G-code and CNC controls such as Fanuc, Mazak, or similar.
• Strong understanding of feeds, speeds, tooling selection, and process optimization.
• Strong problem-solving skills and attention to detail.

Preferred Qualifications

• Associate's or Bachelor's degree in Manufacturing Engineering, Mechanical Engineering, or a related field.
• Experience programming 4-axis or 5-axis machining centers.
• Familiarity with CAD software such as Inventor or AutoCAD.
• Lean Manufacturing or Six Sigma experience.
• Experience in a high-mix, low-volume job shop environment.
