Job Description

Mace Machine LLC – Exeter, New Hampshire

Mace Machine is seeking an experienced Swiss CNC Programmer/Machinist with strong ESPRIT CAM experience who can take complex precision parts from print to successful production. This is an advanced, hands-on position for someone confident in programming, setup, troubleshooting, and optimization of Swiss-style CNC machines.

We are a growing precision machine shop specializing in small-diameter components for the aerospace, defense, RF/microwave, electronics, and other demanding industries. Our work is high-mix and technically challenging, with a strong emphasis on quality, process ownership, and continuous improvement.

What You’ll Do

• Create, edit, and optimize Swiss CNC programs using ESPRIT CAM
• Program, set up, and operate Citizen Swiss-style CNC machines
• Develop complete machining processes from customer drawings and specifications
• Select tooling, workholding, cutting strategies, and machining parameters
• Program live-tooling, milling, cross-working, and back-working operations
• Produce complex components complete in a single cycle whenever practical
• Troubleshoot programming, tooling, dimensional, and production issues
• Optimize cycle times while maintaining quality and process stability
• Perform first-piece and in-process inspections using precision measuring equipment
• Make offsets and process adjustments based on inspection results
• Document programs, setups, tooling, and proven manufacturing methods
• Support and mentor less-experienced machinists
• Participate in process improvement, setup reduction, and manufacturability reviews

What We’re Looking For

• Advanced experience programming and setting up Swiss-style CNC machines
• Demonstrated proficiency with ESPRIT CAM
• Experience with Citizen machines and FANUC or Mitsubishi controls
• Strong knowledge of Swiss turning, live tooling, milling, cross-working, and back-working
• Ability to independently interpret complex blueprints, GD&T, and customer specifications
• Experience selecting tooling and developing efficient machining processes
• Strong troubleshooting and problem-solving skills
• Proficiency with micrometers, indicators, gage pins, optical inspection equipment, and other precision instruments
• Thorough understanding of speeds, feeds, tool geometry, material behavior, and process control
• Experience machining tight-tolerance parts from stainless steel, aluminum, brass, copper alloys, and engineering plastics
• Ability to produce accurate, repeatable work with limited supervision
• Strong attention to detail and commitment to quality

Experience in aerospace, defense, or an AS9100 manufacturing environment is beneficial but not required.
