Full Job Description

Senior Precision Machinist (CNC Mills/Lathes & Toolroom)

A Day in the Shop

Your shift begins at a tidy setup station. You review advanced blueprints, note critical GD&T callouts, verify tooling offsets, and prep a horizontal mill for the first run. You load and run a CNC program, watch the first-off part closely, and make smart adjustments to hold tolerance and improve machine efficiency. Before the next job, you switch seamlessly to a manual lathe for a rework cut—then rig and flip a heavy component using the overhead crane with practiced, safe motions. Throughout the day, you inspect parts with micrometers, indicators, calipers, scales, and a profilometer, documenting results and keeping the shop tooling in top shape.

What You’ll Handle

Operate safely and efficiently across turning, milling, drilling, reaming, boring, slotting, grinding, and tapping.
Set up and run CNC vertical and horizontal mills and lathes; load programs and verify accuracy and throughput.
Troubleshoot machining challenges and fine-tune processes to maintain quality and productivity.
Maintain precise documentation for work performed and inspection outcomes.
Rig, move, and flip heavy parts using overhead cranes while following all safety procedures and PPE requirements.
Monitor, maintain, and care for shop tooling to ensure readiness and capability.
Read and interpret complex blueprints; apply advanced GD&T and process knowledge.
Measure and report dimensional features using scales, calipers, micrometers, profilometers, indicators, and related inspection equipment.

What You Bring

At least 10 years of combined CNC and manual machining experience.
Advanced understanding of blueprints, manufacturing processes, and GD&T.
Advanced metrology skills and confidence with precision inspection tools.
Knowledge of rigging and safe overhead crane use.
Positive attitude, reliable attendance, and a commitment to a safety‑focused, efficient culture.
Ability to work weekends and overtime as needed and to stand for extended periods.
