Full description
About the role
- The Machinist I is an entry-level CNC operator learning to safely run stable jobs on Master Machine's floor. This role loads programs, performs tool changes, inspects basic features per setup sheets, and builds the machining fundamentals needed to progress to Machinist II.
- This role is evaluated on two equally weighted dimensions: Competency (what you do) and Culture (how you do it).
Big 3 - Competency // What you'll do
- Safe CNC Machine Operation
Operate assigned CNC machines under supervision, following the setup sheet, safety procedures, and standard work so parts run to spec on stable jobs.
Machine Operation & Tool Changes
- Load programs and perform tool changes per the setup sheet and standard work
- Run stable, released jobs on CNC mills, lathes, or grinders under supervision
- Monitor cuts and stop the machine if something looks, sounds, or measures wrong
Safety, LOTO & PPE
- Follow OSHA, LOTO, and Master Machine safety and PPE requirements at all times
- Inspect machines and tooling before use and flag anything unsafe before starting
- Report hazards, near-misses, and unsafe conditions immediately to the supervisor
- Basic Part Inspection & Documentation
Perform basic in-process inspections with calipers, micrometers, and indicators, and record results honestly on the traveler so every part has a defensible history.
Measurement & Print Reading
- Read basic blueprints, notes, and tolerances to know what to check
- Use precision measurement tools (calipers, micrometers, indicators, height gauges) correctly
- Verify basic features per the setup sheet before running the next part
Traceability & Documentation
- Record measurements and production steps on the traveler accurately and completely
- Escalate out-of-tolerance parts or non-conformances per quality procedure
- Keep first-piece and in-process records legible and traceable back to the job
- Fundamentals, Learning & 5S
Build the machining fundamentals — G-code awareness, offsets, workholding, and 5S — needed to grow into Machinist II, and keep the cell clean and organized.
Learning G-code, Offsets & Fundamentals
- Learn basic G-code, tool offsets, and workholding fundamentals from senior machinists
- Ask questions when a print, program, or setup sheet is not clear
