Computer Numerical Control Machinist

REIOS Recruitment; Boston (MA); On-site; USD 80,000 - 110,000; Full time

Job summary

REIOS Recruitment in Massachusetts seeks an experienced CNC machinist to own machining and post-processing for 3D printed production parts across aerospace, automotive, medical, and industrial sectors. You’ll program, set up, prove out, and determine how parts are held, cut, and finished.

You will write CAM programs, edit G-code, and run 3-, 4-, and 5-axis mills and a CNC lathe, with fixtures, CMM inspection, and continuous improvement shaping the process as production grows.

Qualifications

• Hands-on CNC programming and setup from drawings or models.
• 3-axis milling at minimum; 5-axis experience is a plus.
• Proficiency in SolidWorks or equivalent CAD with GD&T.
• US citizen or green card holder; export controlled work.

Responsibilities

• Write CAM programs and edit G-code; set up and prove out parts on 3-, 4-, and 5-axis mills and a CNC lathe, primarily Fanuc controls.
• Design fixtures and workholding for near-net-shape printed parts that behave differently from billet.
• Machining parts on and off the build plate; wire EDM cut-off, grinding and secondary ops.
• Determine post-processing sequence and write clear work instructions for repeatability.
• Set up CMM inspection and perform first article inspections against drawings.
• Perform root cause analysis when parts are out of tolerance and communicate design changes to print team.

Job description

This is a role with a metal additive manufacturing business in Massachusetts that makes 3D printed production parts for customers in aerospace, automotive, medical and industrial, and they need someone to own the machining and post processing side of getting a printed part off the build plate and into the customer’s hands.

You’d be doing the CNC programming, setting the parts up, proving them out and running them yourself, and deciding how every printed part gets held, cut and finished. It suits an experienced CNC programmer or machinist who wants to stay close to the machines and also wants an engineering title and a real say in how the process gets built.

It’s a small engineering team and you’d be coming in early, so you get to set how machining is done as production grows and they bring technicians in.

Responsibilities

• Writing programs in CAM and editing G code at the machine, then setting up and proving out parts yourself on 3 axis, 4+1 and 5 axis mills and a CNC lathe, mostly on Fanuc controls
• Fixture design and work holding for near net shape printed parts, which behave differently to billet
• Machining parts on and off the build plate, plus wire EDM cut off, grinding and other secondary ops
• Working out what order the post processing steps happen in and writing the work instructions so anyone can repeat it
• Setting up CMM inspection and first article against customer drawings
• Root cause analysis when a part comes out of tolerance, and feeding design changes back to the print team so the next one is easier to hold and machine

Requirements

• Hands on CNC programming and setup, writing your own programs from a drawing or model
• 3 axis milling as a minimum, with 5 axis machining experience or a real wish to get into it
• Comfortable in SolidWorks or similar CAD and working to tight tolerances with GD&T
• US citizen or green card holder, as the work is export controlled
