CNC Machinist

Overview

We're hiring CNC Machinists for our aerospace and defense machine shop outside of Walnut, CA

We machine frames and structural components for defense platforms–true large-format work, on parts most machinists never get their hands on.

If your fundamentals are strong, we'll train you on large-format gantry mills, 5-axis machining centers, and supporting CNC mills and lathes.

Why Join Us

• Hone your craft: Get trained up on unique large-format gantry mills
• High-impact work: Frames and structural components for high-stakes defense platforms
• Financial impact: 45-hour weeks, additional overtime, night shift differential

Responsibilities

• Setups: Load and verify programs, tools, offsets, and fixtures from setup sheets
• Machining: Set up and operate CNC milling and turning centers, including large-format work
• Dimensional Accuracy: Adjust machine parameters, offsets, and tooling to hold tight tolerances
• Blueprints & GD&T: Work from complex aerospace prints and customer specifications
• Inspection: Precise measurement with calipers, micrometers, and other precision instruments

What You'll Run

Equipment: Large-format gantry mills, 5-axis machining centers, and supporting CNC mills and lathes

Parts: Frames and structural components for defense platforms

You don't need large-format or gantry experience. If you're a 3, 4, or 5-axis machinist with strong fundamentals and solid setup skills, we'll train you on the big machines.
