Job description

We are partnering with an established precision manufacturing organization in Irvine, CA, seeking an experienced CNC Programmer/Machinist to join its team.

This opportunity is ideal for a highly skilled, hands-on CNC professional who enjoys both programming and machining complex, precision components. The successful candidate will take ownership of CNC programming, machine setups, first-article production, and process optimization while collaborating closely with engineering and manufacturing teams.

This is a hands-on programming position, not solely a CNC machine operator role. We are specifically seeking individuals with advanced Mastercam experience and a strong background in multi-axis CNC machining.

Key Responsibilities

• Develop, modify, and optimize CNC programs using Mastercam, primarily for 4- and 5-axis CNC milling machines and CNC mill-turn lathes.
• Independently perform CNC machine setups, tooling selection, and first-article production.
• Interpret complex engineering drawings, 3D models, technical specifications, and machining requirements.
• Troubleshoot machining and programming challenges to improve quality, efficiency, and cycle times.
• Operate CNC machines as needed to support production schedules.
• Collaborate with engineering, quality inspection, and assembly teams to ensure components meet specifications.
• Support root cause analysis, corrective actions, and continuous process improvements.
• Provide technical guidance and training to other machining team members.

Required Qualifications

• 5+ years of professional CNC programming and machining experience.
• Strong hands-on experience programming with Mastercam.
• Experience programming 4-axis and 5-axis CNC milling machines.
• Proven ability to independently program, set up, and troubleshoot CNC machining operations.
• Strong understanding of machining processes, tooling, tolerances, and technical drawings.
• Ability to interpret 3D models using SolidWorks and 2D drawings using AutoCAD.
• Strong problem-solving skills and ability to work independently in a precision manufacturing environment.

Preferred Qualifications

• Experience working with complex, tight-tolerance machined components.
• Familiarity with Epicor ERP.
• Experience mentoring or training other machinists.
• Demonstrated success improving machining processes, reducing cycle times, and resolving production challenges.

Who We're Looking For

We're particularly interested in experienced CNC Programmers who have progressed beyond machine operation and can independently take a part from an engineering drawing through programming, setup, and successful first-article production.

If you have a strong background in Mastercam, multi-axis CNC milling, and hands-on precision machining, we'd love to connect!
