Prototype Machinist (7:00am to 3:30pm)

The role

You will take ownership of precision machined parts from start to finish in a prototype and R&D environment. This includes material selection, CAM programming, CNC setup, and inspection to turn complex designs into hardware.

What you will do

• Read and interpret engineering drawings, CAD models, GD&T callouts, and work instructions.
• Own machined parts from planning and programming through machining and delivery.
• Program, set up, troubleshoot, and operate 3-axis and 5-axis CNC mills and lathes.
• Develop CAM programs using Fusion 360 or similar platforms.
• Design setups, fixtures, soft jaws, and vacuum fixtures for prototype parts.
• Select tools, create tool lists, and order tooling and materials.
• Machine precision parts from aluminum, titanium, stainless steel, ceramics, and engineering polymers.
• Inspect parts using CMM data, calipers, micrometers, height gauges, and indicators.
• Collaborate with engineering to identify manufacturability risks and improve designs.
• Manage multiple jobs based on priority, due dates, and machine capacity.

Required qualifications

• High school diploma, GED, or equivalent practical experience.
• 2+ years of hands-on CNC machining experience in aerospace, medical device, semiconductor, robotics, automotive, or another high precision industry.
• Strong experience programming, setting up, proving out, and operating CNC mills and lathes, including 3-axis and 5-axis machining.
• Experience with toolpath strategy, tool selection, work offsets, probing, setup verification, and process troubleshooting.
• Demonstrated proficiency with at least one modern CAM platform.
• Strong understanding of machining fundamentals, including feeds and speeds, tool wear, surface finish, workholding, rigidity, and tolerance stackup.
• Ability to read complex prints, interpret GD&T, and hold tight tolerances.
• Strong inspection and metrology skills.
• Ability to design practical fixtures, soft jaws, and custom tooling for prototype parts with limited direction.
• Experience working in a fast-paced prototype, R&D, or low-volume production environment.
• Ability to manage multiple projects at once and reprioritize quickly.
• Clear and proactive communication style.

Nice to have

• Fusion 360 experience is strongly preferred.
