The Role
Complete Metal Design is hiring a CNC Setup Machinist for our mill and lathe departments. This is a setup-first role. Your main job is getting machines dialed in: our programmer hands you a proven job with a setup sheet, tool list, and program notes, and you build the setup, verify the first piece is on print, and get the job running clean.
Most of the time, once a job is proven and stable, an operator takes it from there and you move to the next setup. But this isn't a setup-only seat - when the schedule calls for it, you'll run production too. Short runs, hot jobs, or days when setups are caught up, you're on a machine making parts.
If you take pride in a tight, fast setup and don't mind running the job you just dialed in when the shop needs it, this is your seat.
What You'll Do
Setup (the main job):
Read the setup sheet, tool list, and program notes from the programmer and execute the setup as proven.
Build the workholding - vises, chucks, soft jaws, fixtures - and dial it in accurately.
Load tools, touch off, set tool and work offsets, and stage the program.
Run the first piece, measure it against the print, and confirm dimensions before the job goes into production.
Hand off cleanly to the operator running the job - walk them through anything that isn't in the paperwork.
Flag anything that doesn't match the proveout and pull the programmer back in when the process needs a real fix.
Keep tooling, workholding, and staging areas organized so setups don't waste time.
Running production (the smaller part):
Run short jobs, hot jobs, and production when setups are caught up.
Manage tool wear, swap inserts, and adjust offsets to hold tolerance through the run.
Inspect in-process with calipers, micrometers, indicators, and height gauges.
Across both:
Move between the mill and lathe side as the schedule demands.
Document process notes that help the next person on the job.
Help train operators and newer setup people.
Who Fits
3+ years of hands-on CNC experience with real setup time on both mills and lathes - not just running parts someone else set up.
Strong on workholding fundamentals and confident dialing in a first piece from a setup sheet.
Comfortable at the control: touching off tools, setting offsets, making small edits at the machine.
Solid grasp of speeds, feeds, tool selection, and how aluminum, steel, stainless, and non-ferrous metals behave.
Read prints and interpret GD&T well enough to verify a first piece matches spec.
Fast without being sloppy - this seat is measured on setup quality and turnaround.
Reliable, organized, and communicates cleanly with programmers and operators.
Even Better If You've Got
CNC lathe live tooling setup experience.
Multi-axis (4-axis or 5-axis) setup experience.
Aerospace or other tight-tolerance production background.
Experience training operators or junior setup people.
Bilingual English / Spanish.
What We Offer
Competitive pay based on experience
Health and dental
Paid time off and holidays
401(k) / CalSavers
Stable, growing shop with a mix of prototype, production, and aerospace work
A team that treats setup as a real trade and gives you ownership of your work
