Machine Shop Maintenance Technician
Precision Manufacturing
This Isn't Your Average Maintenance Job
Most maintenance roles hand you a checklist and tell you to follow it. This one hands you a blank page and asks you to write it.
A well-established precision manufacturing company in the St. Charles, IL area is looking for a Maintenance Technician who wants to build something from the ground up. The preventive maintenance program for their CNC machine shop doesn't fully exist yet. The schedule, the tracking system, the OEM relationships — that's yours to own. If you're the type of person who looks at a disorganized machine floor and sees a problem worth solving, keep reading.
What You'll Actually Be Doing
This is a dedicated machine shop maintenance role — focused entirely on keeping CNC equipment (Haas, Mazak, and more) running at peak performance. You won't be pulling fire alarms or doing building HVAC work. You're here for the machines.
In your first 90 days, you'll:
Get to know every one of 24 CNC machines — their history, their quirks, their needs
Reach out directly to Haas, Mazak, and other OEMs to pull their recommended maintenance schedules
Build a preventive maintenance plan from scratch and put it into action
Set up a maintenance tracking system (CMMS or well-structured Excel — your call to start) so nothing slips through the cracks
Learn from a veteran in-house maintenance lead with decades of institutional knowledge — be a sponge
On an ongoing basis, you'll:
Execute a rolling PM schedule — 2 machines per month taken offline for full inspection, cleaning, lubrication, and servicing
Perform mechanical maintenance on CNC mills, lathes, grinders, and related equipment
Troubleshoot and repair mechanical, pneumatic, hydraulic, and basic electrical systems
Coordinate with OEM technicians (Haas, Mazak) when heavy technical support is needed — you don't have to be the wizard, but you need to know when to call one
Communicate proactively with the production planning team so maintenance windows are scheduled around production commitments — not against them
Maintain accurate maintenance logs and uptime records
Manage spare parts inventory and reordering
Assist with equipment installation, relocation, and setup as needed
Follow all LOTO, OSHA, and safety protocols without exception
What We're Looking For
You're the right person if you:
Have hands-on experience with CNC equipment — any brand, any level — and genuinely enjoy being around machines
Are a self-starter who doesn't wait to be told what needs to be done
Can read technical manuals, OEM documentation, and schematics and turn that information into a workable plan
Are mechanically strong and not intimidated by electrical systems (you don't need to be an electrician — but you can't be afraid of a control panel)
Take pride in keeping good records and running a tight, organized operation
Communicate clearly with production and operations teams
Are comfortable with a little flexibility in schedule when a machine goes down on second shift
Preferred background:
3–5 years of mechanical maintenance experience in a manufacturing environment
CNC machine experience (operation, maintenance, or both)
Familiarity with CMMS platforms or strong organizational systems
Knowledge of precision measuring instruments (calipers, micrometers, etc.)
LOTO certified or willing to obtain
Education: High school diploma or equivalent required; technical/vocational training a plus
Additional Information
Schedule: Monday–Friday, 7 AM–4 PM (some second shift flexibility appreciated)
Employment type: Full-time, direct hire, non-union
Tools: Bring your own if you have them; the company will make sure you have what you need either way
Room to Grow
This company has a defined machinist progression and is building out a parallel career track on the maintenance side. If you want to grow into a higher-level maintenance role, pursue a machinist apprenticeship, or move into another area of the operation over time, this is a place where that path exists.
Why This Role Matters
When the machines aren't running, parts aren't being made — and customers feel it. The person in this role has a direct line to operational efficiency and on-time delivery. Leadership is ready to compensate accordingly for someone who truly owns it.
