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.

• 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

• 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.

At Mace Machine, experienced machinists are trusted to think, solve problems, and take ownership of their work. Employee ideas are valued because the people closest to the process often know best how to improve it.

We offer:

• Competitive compensation based on experience and ability
• Health insurance contribution
• Paid time off
• 401(k) with company match
• Opportunities for overtime
• Challenging, varied work—not repetitive button pushing
• Modern Swiss machining equipment
• A cooperative, team-oriented work environment
• Meaningful involvement in process improvement and company growth
• Opportunities to expand your technical and leadership responsibilities

You should be proficient in:

• GD&T
• Equipment Troubleshooting
• Troubleshooting Skills
• CNC Programming
• G-Code
• M-Code
• CNC Machine Setup & Changeover
• Precision Measurement & Hand Metrology
