About The Position

We are seeking a Prototype Programmer and Machinist to contribute to the success of a growing machine shop. In this role, you’ll be primarily focused on programming one-off, highly complex parts (80% programming), while also handling setup and operation of 3-5 axis mills and CNC lathes. If you’re a hands-on individual who enjoys seeing parts through from concept to completion, this is your chance to work on truly unique projects in a fast-moving, tech-forward environment.

Requirements

• 3+ years of experience as a CNC Programmer and/or Machinist, ideally in a prototype or R&D environment
• Proficiency with CAM software such as MasterCAM, HSMWorks, or similar
• Strong knowledge of 3-axis and 5-axis CNC milling, and/or lathe programming
• Hands-on experience with machine setup, tooling selection, and operation
• Ability to read and interpret engineering drawings, GD&T, and technical documentation
• Familiarity with precision measurement tools (micrometers, calipers, indicators, etc.)
• Comfortable taking parts from concept to finished product independently
• Strong attention to detail and commitment to producing high-quality work

Responsibilities

• Program CNC machines (3-axis, 5-axis mills, and lathes) for one-off and short-run prototype parts using MasterCAM or HSMWorks
• Collaborate with engineering and design teams to review technical drawings, provide manufacturability feedback, and ensure design intent is achieved
• Set up and operate CNC machines, selecting appropriate tools, fixtures, and materials for each job
• Perform in-process inspections using precision measuring tools to ensure quality and tight tolerances
• Troubleshoot and optimize programs and setups for improved efficiency and part quality
• Maintain accurate documentation, including setup sheets, tooling lists, and job traveler updates
• Support continuous improvement efforts by contributing ideas to enhance machining strategies, tooling, and workflow
• Take ownership of your projects from cradle to grave — from programming to final inspection

Benefits

• PTO
• Medical & Dental Insurance, with plans offering up to 100% employer coverage
• 401(k) with company contributions
• State-of-the-art facility with the latest equipment and technology
• Catered lunches and snacks
• Quarterly celebrations and company events
• Equity ownership opportunities as the company grows
